CVE-2022-40719: D-Link DIR-2150 xupnpd_generic Plugin Command Injection Remote Code Execution Vulnerability
This vulnerability allows network-adjacent attackers to execute arbitrary commands on affected installations of D-Link DIR-2150 4.0.1 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the xupnpdgeneric.lua plugin for the xupnpd service, which listens on TCP port 4044 by default. When parsing the feed parameter, the process does not properly validate 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 service account. Was ZDI-CAN-15906.
