CVE-2026-2163Public exploitNetwork attack vector

Authenticated command execution via unsanitized CGI variables

Published Feb 8, 2026 · Updated Feb 8, 2026

Command injection in ssdp.cgi in D-Link DIR-600 2.15WWb02 allows remote authenticated users to execute operating-system commands. The CGI handler reads HTTP_ST, REMOTE_ADDR, REMOTE_PORT, and SERVER_ID with getenv, then concatenates their unfiltered values for execution through lxmldbc_system and system. High-privilege access to the router management interface is required, and successful exploitation grants command execution in the firmware context.
