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 issue arises in the 'goform/formdumpeasysetup' endpoint, where the 'curTime' parameter can be manipulated to cause the 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/formdumpeasysetup' endpoint. Include a 'curTime' parameter with a payload that exceeds the buffer limit, effectively causing a stack buffer overflow.
