Belkin F9K1015 Buffer Overflow Vulnerability in formSetLanguage

Vulnerability

A buffer overflow vulnerability has been identified in the Belkin F9K1015 router, specifically in version 1.00.10. The issue arises in the file '/goform/formSetLanguage', where the 'webpage' parameter is processed without proper length validation. This oversight allows for 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 the device to crash.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/goform/formSetLanguage' with a 'webpage' parameter that is excessively long. This unvalidated input will overflow the stack-based buffer, triggering the vulnerability.
