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/formEasySetupWizard' component, 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/formEasySetupWizard' endpoint. Include a 'curtime' parameter with a payload that exceeds the buffer limit, effectively causing a stack buffer overflow.
