CVE-2025-34036

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2025-34036
An OS command injection vulnerability exists in white-labeled DVRs manufactured by TVT, affecting a custom HTTP service called "Cross Web Server" that listens on TCP ports 81 and 82. The web interface fails to sanitize input in the URI path passed to the language extraction functionality. When the server processes a request to /language/[lang]/index.html, it uses the [lang] input unsafely in a tar extraction command without proper escaping. This allows an unauthenticated remote attacker to inject shell commands and achieve arbitrary command execution as root. Exploitation evidence was observed by the Shadowserver Foundation on 2025-08-27 UTC.

Summary
  • (es) Existe una vulnerabilidad de inyección de comandos del sistema operativo en los DVR de marca blanca fabricados por TVT, que afecta a un servicio HTTP personalizado llamado "Cross Web Server" que escucha en los puertos TCP 81 y 82. La interfaz web no depura la entrada en la ruta URI enviada a la función de extracción de idioma. Cuando el servidor procesa una solicitud a /language/[lang]/index.html, utiliza la entrada [lang] de forma insegura en un comando de extracción de tar sin el escape adecuado. Esto permite que un atacante remoto no autenticado inyecte comandos de shell y ejecute comandos arbitrarios como root.
