Belkin F9K1015 Buffer Overflow Vulnerability in WPS Start Function

A buffer overflow vulnerability has been identified in the Belkin F9K1015 router, specifically in version 1.00.10. The issue arises in the '/goform/formWpsStart' function, where the 'pinCode' parameter is processed without proper length validation. This oversight allows for a stack-based buffer overflow, which can be exploited remotely.

Impact

Exploitation of this vulnerability leads to a stack-based buffer overflow, which can commonly result in arbitrary code execution or causing a denial-of-service condition.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/goform/formWpsStart' with a 'pinCode' parameter that exceeds the buffer's capacity. The lack of length checking allows the oversized input to overflow the stack-based buffer, creating the potential for exploitation.
