Tenda AC18 router v15.03.05.19 and v15.03.05.05 was discovered to contain a stack overflow via the list parameter at /goform/SetVirtualServerCfg.

**Tenda AC18 Unauthorized stack overflow vulnerability******1\. Affected version:****

V15.03.05.05\_multi and V15.03.05.19\_multi

****2\. Firmware download address****

https://www.tenda.com.cn/download/detail-2683.html

****3\. Vulnerability details****

In function formSetVirtualSer, the content obtained by the program from the list parameter is passed to v5, and then calls sub\_76510 function, let's follow up and check.

At this time, the position of a2 parameter in the corresponding function.

After that, a2 is assigned to v5, and then the matched content in v5 is directly formatted into the stack of v10, v11, v12 and v9 through the function sscanf through regular expression. There is a stack overflow vulnerability. The attacker can easily perform a Deny of Service Attack or Remote Code Execution with carefully crafted overflow data.

****4\. Recurring vulnerabilities and POC****

In order to reproduce the vulnerability, the following steps can be followed:

1.Use the fat simulation firmware V15.03.05.19\_multi

2.Attack with the following overflow POC attacks
