Descriptions
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of TP-Link Archer A7 Firmware Ver: 190726 AC1750 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the tdpServer service, which listens on UDP port 20002 by default. When parsing the slave_mac parameter, the process does not properly validate 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 the root user. Was ZDI-CAN-9650.
Esta vulnerabilidad permite a atacantes adyacentes a la red ejecutar código arbitrario sobre las instalaciones afectadas de enrutadores AC1750 TP-Link Archer A7 Versión de Firmware: 190726. No es requerida una autenticación para explotar esta vulnerabilidad. El fallo específico se presenta dentro del servicio tdpServer, que escucha en el puerto UDP 20002 por defecto. Al analizar el parámetro slave_mac, el proceso no comprueba apropiadamente una cadena proporcionada por el usuario antes de usarla para ejecutar una llamada de sistema. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto del usuario raíz. Fue ZDI-CAN-9650.
