Summary

A command execution vulnerability exists in the D-Link DIR-2150 4.0.1 router, allowing network-adjacent attackers to execute arbitrary commands without authentication. This issue is due to insufficient validation of user-supplied input in the xupnpd_generic.lua plugin of the xupnpd service, which operates on TCP port 4044. Attackers can exploit this flaw by crafting a malicious request that triggers unauthorized system calls, potentially compromising the device and the network it connects to. Users are advised to apply available security updates promptly to mitigate this risk.
