| Title | Tenda F453 v1.0.0.3 Stack-based Buffer Overflow |
|---|
| Description | A vulnerability was found in Tenda F453 v1.0.0.3. Affected by this vulnerability is the function fromPPTPUserSetting of the file /goform/PPTPUserSetting of the component httpd. The manipulation of the argument delno with an unknown input leads to a buffer overflow vulnerability.In fromPPTPUserSetting function,it reads in a user-provided parameter delno.If the value of delno is not empty, the variable s_1 will be passed to s_3.Finally, the variable s_3 is passed to the sprintf function without any length check, which may overflow the stack-based buffer s__1.As a result, by requesting the page, an attacker can easily execute a denial of service attack or remote code execution. |
