HIGH 8.8

DescriptionCVE.org

A vulnerability has been found in D-Link DWR-M960 1.01.07. This affects the function sub_4196C4 of the file /boafrm/formVpnConfigSetup of the component VPN Configuration Endpoint. The manipulation of the argument submit-url leads to stack-based buffer overflow. The attack is possible to be carried out remotely. The exploit has been disclosed to the public and may be used.

AnalysisAI

Remote code execution in D-Link DWR-M960 firmware through a stack buffer overflow in the VPN configuration endpoint allows authenticated attackers to execute arbitrary code by manipulating the submit-url parameter. The vulnerability affects firmware version 1.01.07 and public exploit code exists, though no patch is currently available.
