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 'formSetSystemSettings' function within the '/goform/formSetSystemSettings' file, part of the Setting Handler component. The vulnerability is triggered by manipulating the 'webpage' argument, which is passed to the 'strcpy' function without proper length validation, leading to a stack overflow. This vulnerability can be exploited remotely, and there is a public proof-of-concept available.

Impact

Exploitation of this vulnerability allows for stack-based buffer overflow, which could 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/formSetSystemSettings' with a 'webpage' parameter containing a payload that exceeds the buffer size, effectively overwriting the stack.
