D-Link DIR-2150 xupnpd_generic Plugin Command Injection Remote Code Execution Vulnerability
Vulnerability Details
This vulnerability allows network-adjacent attackers to execute arbitrary commands on affected installations of D-Link DIR-2150 routers. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the xupnpd_generic.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.
