Actiontec WCB6200Q Cookie Format String 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. A crafted Cookie header in an HTTP request can trigger the use of a format specifier from a user-supplied string. An attacker can leverage this vulnerability to execute code in the context of the HTTP server. Was ZDI-CAN-21417.
Vulnerabilidad de ejecución remota de código de cadena de formato de cookie Actiontec WCB6200Q. 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. Un encabezado de cookie manipulado en una solicitud HTTP puede desencadenar el uso de un especificador de formato a partir de una cadena proporcionada por el usuario.
