CVE-2025-34037

An OS command injection vulnerability exists in various models of E-Series Linksys routers via the /tmUnblock.cgi and /hndUnblock.cgi endpoints over HTTP on port 8080. The CGI scripts improperly process user-supplied input passed to the ttcp_ip parameter without sanitization, allowing unauthenticated attackers to inject shell commands. This vulnerability is exploited in the wild by the "TheMoon" worm to deploy a MIPS ELF payload, enabling arbitrary code execution on the router. This vulnerability may affect other Linksys products to include, but not limited to, WAG/WAP/WES/WET/WRT-series router models and Wireless-N access points and routers.

Summary		(es) Existe una vulnerabilidad de inyección de comandos del sistema operativo en varios modelos de routers E-Series Linksys a través de los endpoints /tmUnblock.cgi y /hndUnblock.cgi a través de HTTP en el puerto 8080. Los scripts CGI procesan incorrectamente la entrada proporcionada por el usuario al parámetro ttcp_ip sin sanitizarla, lo que permite a atacantes no autenticados inyectar comandos de shell. Esta vulnerabilidad es explotada por el gusano "TheMoon" para desplegar un payload MIPS ELF, lo que permite la ejecución de código arbitrario en el router. Esta vulnerabilidad puede afectar a otros productos Linksys, incluyendo, entre otros, los modelos de routers de las series WAG/WAP/WES/WET/WRT y los puntos de acceso y routers Wireless-N.
