Actiontec WCB6200Q uh_tcp_recv_header Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Actiontec WCB6200Q routers. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the HTTP server. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length buffer. An attacker can leverage this vulnerability to execute code in the context of the HTTP server. Was ZDI-CAN-21414.
Vulnerabilidad de ejecución remota de código por desbordamiento del búfer en Actiontec WCB6200Q uh_tcp_recv_header. Esta vulnerabilidad permite a atacantes adyacentes a la red ejecutar código arbitrario en instalaciones afectadas de enrutadores Actiontec WCB6200Q. No se requiere autenticación para aprovechar esta vulnerabilidad. La falla específica existe dentro del servidor HTTP. El problema se debe a la falta de una validación adecuada de la longitud de los datos proporcionados por el usuario antes de copiarlos en un búfer de longitud fija. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto del servidor HTTP. Era ZDI-CAN-21414.
