Descriptions
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DAP-1860 1.04B03_HOTFIX WiFi extenders. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the HNAP service, which listens on TCP port 80 by default. When parsing the SOAPAction header, 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 device. Was ZDI-CAN-10084.
Esta vulnerabilidad permite a atacantes adyacentes a la red ejecutar código arbitrario en las instalaciones afectadas de los extensores WiFi D-Link DAP-1860 1.04B03_HOTFIX. Aunque es requerida una autenticación para explotar esta vulnerabilidad, el mecanismo de autenticación existente puede ser omitido. El fallo específico se presenta dentro del servicio HNAP, que escucha en el puerto TCP 80 por defecto. Cuando se analiza el encabezado SOAPAction, el proceso no comprueba correctamente una cadena proporcionada por el usuario antes de usarla para ejecutar una llamada al sistema. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto del dispositivo. Fue ZDI-CAN-10084
