Belkin F9K1122 Stack-Based Buffer Overflow Vulnerability in Parameter Handler

A stack-based buffer overflow vulnerability has been identified in the Belkin F9K1122 router, specifically in version 1.00.33. The issue arises in the 'formSetPassword' function within the '/goform/formSetPassword' file, where the 'webpage' parameter is manipulated without proper length validation. This oversight allows for remote exploitation, potentially leading to unauthorized code execution or a denial-of-service condition.

Impact

Exploitation of this vulnerability allows for remote code execution or a denial-of-service condition on the affected device.

Reproduction

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