Tenda FH1202 Stack-Based Buffer Overflow Vulnerability

A stack-based buffer overflow vulnerability has been identified in the Tenda FH1202 router, specifically in version 1.2.0.14. The issue arises in the httpd component, within the function 'fromWrlclientSet' of the file '/goform/WrlclientSet'. The vulnerability can be exploited remotely by manipulating the 'GO' parameter, leading to potential denial-of-service conditions or arbitrary code execution.

Impact

Exploitation of this vulnerability allows for stack-based buffer overflow, which can lead to arbitrary code execution or a denial-of-service condition.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/goform/WrlclientSet' with a 'GO' parameter that contains a payload designed to overflow the stack buffer. This can be done using a web browser or a tool like curl, by specifying the appropriate headers and cookie information.
