Descriptions

D-Link DIR-X3260 SetSysEmailSettings EmailFrom Command Injection Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DIR-X3260 routers. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the prog.cgi program, which handles HNAP requests made to the lighttpd webserver listening on TCP ports 80 and 443. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-21102.

D-Link DIR-X3260 SetSysEmailSettings EmailFrom Vulnerabilidad de ejecución remota de código de inyección de comando. Esta vulnerabilidad permite a atacantes adyacentes a la red ejecutar código arbitrario en instalaciones afectadas de enrutadores D-Link DIR-X3260. Aunque se requiere autenticación para aprovechar esta vulnerabilidad, se puede omitir el mecanismo de autenticación existente. La falla específica existe dentro del programa prog.cgi, que maneja las solicitudes HNAP realizadas al servidor web lighttpd que escucha en los puertos TCP 80 y 443. El problema se debe a la falta de validación adecuada de una cadena proporcionada por el usuario antes de usarla para ejecutar un llamado de sistema. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto de la raíz. Era ZDI-CAN-21102.
