D-Link DIR-619L Stack-Based Buffer Overflow Vulnerability

A critical stack-based buffer overflow vulnerability has been identified in the D-Link DIR-619L router, specifically in version 2.06B01. The issue arises in the 'formSetACLFilter' function within the file '/goform/formSetACLFilter', where the 'curTime' argument can be manipulated, leading to arbitrary code execution. This vulnerability can be exploited remotely and affects a product that is no longer supported by the manufacturer.

Impact

Exploitation of this vulnerability allows for a stack-based buffer overflow, which could be used to execute arbitrary code on the affected device.

Reproduction

To reproduce this vulnerability, send a crafted request to the '/goform/formSetACLFilter' endpoint, manipulating the 'curTime' argument with an excessively long input. This will trigger the stack-based buffer overflow condition.
