This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DIR-825 1.0.9/EE routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the Generic plugin for the xupnpd service, which listens on TCP port 4044. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of the admin user. Was ZDI-CAN-19460.
