D-Link DIR-513 Stack Buffer Overflow Vulnerability

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/formSetQoS' 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

The vulnerability can be reproduced by sending a POST request to the '/goform/formSetQoS' endpoint. The request must include a 'curTime' parameter filled with a payload that exceeds the buffer size, effectively causing a stack buffer overflow.
