| 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 fromPptpUserAdd of the file /goform/PPTPDClient of the component httpd. The manipulation of the argument username and opttype with an unknown input leads to a buffer overflow vulnerability.In fromPptpUserAdd function,it reads in a user-provided parameter username and opttype.If the value of opttype is 1, the variable v21 will be passed to the sprintf function without any length check, which may overflow the stack-based buffer s__3.As a result, by requesting the page, an attacker can easily execute a denial of service attack or remote code execution. |
