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.

dlink

Directory traversal vulnerability in Mathopd 1.4.x and 1.5.x before 1.5p7, when configured with the * construct for mass virtual hosting, allows remote attackers to read arbitrary files via a crafted Host header.

mathopd

The internal_dump function in Mathopd before 1.5p5, and 1.6x before 1.6b6 BETA, when Mathopd is running with the -n option, allows local users to overwrite arbitrary files via a symlink attack on dump files that are triggered by a SIGWINCH signal.
