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

Vulnerability

A critical stack-based buffer overflow vulnerability has been identified in the D-Link DIR-619L router, specifically in the 2.06B01 firmware version. The issue arises in the 'formSetWAN_Wizard51' function, 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 device.

Reproduction

The vulnerability can be reproduced by sending a crafted request to the '/goform/formSetWAN_Wizard51' endpoint, manipulating the 'curTime' parameter with an excessively long input. This input overflowes the stack buffer, creating the potential to execute arbitrary code.
