Belkin F9K1122 Stack-Based Buffer Overflow Vulnerability in Web Language Setting Function

A critical stack-based buffer overflow vulnerability has been identified in the Belkin F9K1122 router running firmware version 1.00.33. The issue arises in the 'formSetLanguage' function within the '/goform/formSetLanguage' file, where the 'webpage' argument is manipulated, leading to the overflow. This vulnerability can be exploited remotely, with a public proof-of-concept exploit available.

Impact

Exploitation of this vulnerability causes a stack-based buffer overflow, allowing for potential arbitrary code execution.

Reproduction

To reproduce this vulnerability, send a request to the '/goform/formSetLanguage' endpoint with a 'webpage' argument that exceeds the buffer limit. This will trigger the stack-based buffer overflow condition.
