An OS command injection vulnerability exists in multiple D-Link routers (confirmed on DIR-300 rev A v1.05 and DIR-615 rev D v4.13) via the authenticated tools_vct.xgi CGI endpoint. The web interface fails to properly sanitize user-supplied input in the pingIp parameter, allowing attackers with valid credentials to inject arbitrary shell commands. Exploitation enables full device compromise, including spawning a telnet daemon and establishing a root shell. The vulnerability is present in firmware versions that expose tools_vct.xgi and use the Mathopd/1.5p6 web server. No vendor patch is available, and affected models are end-of-life.

otherpingIp↗

→Monitor HTTP requests targeting the CGI endpoint tools_vct.xgi, specifically inspecting the 'pingIp' parameter for shell metacharacters or command injection payloads (e.g., semicolons, pipes, backticks, $() constructs). ↗
→Alert on POST/GET requests to tools_vct.xgi on D-Link DIR-300 and DIR-615 devices, particularly from authenticated sessions, as exploitation requires valid credentials. ↗
→Detect spawning of a telnet daemon process on D-Link routers as a post-exploitation indicator of successful command injection via this vulnerability. ↗
→Fingerprint the web server banner 'Mathopd/1.5p6' to identify potentially vulnerable D-Link devices exposed on the network. ↗

·Exploitation requires valid credentials; this is an authenticated vulnerability, so detections should not be limited to unauthenticated traffic — insider threat or credential theft scenarios are relevant attack vectors. ↗
·Confirmed affected firmware versions are DIR-300 rev A v1.05 and DIR-615 rev D v4.13; other D-Link models may also be affected according to the vulnerability discoverer. ↗
·No vendor patch is available and affected models are end-of-life; network-level controls (firewall, isolation) are the primary mitigation path. ↗
