| Title | Tenda F451_kfw_V1.0.0.7_cn_svn7958 V1.0.0.7 Buffer Overflow |
|---|
| Description | We found an overflow vulnerability in httpd :
In fromAdvSetWan function,it reads in a user-provided parameter wanmode and PPPOEPassword.
If the value of wanmode is 2, the variable v17 is passed to the sub_3C6C0 function without any length check, which may overflow the stack-based buffer s.
As a result, by requesting the page, an attacker can easily execute a denial of service attack or remote code execution. |
