Belkin F9K1015 Stack-Based Buffer Overflow Vulnerability Allowing Remote Code Execution

A stack-based buffer overflow vulnerability has been identified in the Belkin F9K1015 router, specifically in version 1.00.10. The issue arises in the 'formSetFirewall' function within the '/goform/formSetFirewall' file, where the 'webpage' argument is manipulated, leading to a buffer overflow on the stack. This vulnerability can be exploited remotely, and the existence of a public exploit has been confirmed.

Impact

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

Reproduction

The vulnerability can be reproduced by sending a POST request to '/goform/formSetFirewall' with a 'webpage' parameter that contains a payload designed to overflow the stack buffer. This can be done using a tool like Burp Suite or through a custom script that automates the process.
