D-Link DIR-513 Stack Buffer Overflow Vulnerability

A stack buffer overflow vulnerability has been identified in the D-Link DIR-513 router, specifically in version 1.10. The vulnerability arises in the 'goform/formLanguageChange' endpoint, where the 'curtime' parameter can be manipulated to cause the buffer overflow.

Impact

Exploitation of this vulnerability leads to a stack buffer overflow, which can commonly result in arbitrary code execution or causing the device to crash.

Reproduction

To reproduce this vulnerability, send a POST request to the '/goform/formLanguageChange' endpoint. Include a 'curtime' parameter with a payload that exceeds the buffer size, effectively causing a stack buffer overflow. The request should be made with a user agent that mimics a standard web browser.
