Descriptions
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected D-Link DIR-2150 4.0.1 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the anweb service, which listens on TCP ports 80 and 443 by default. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-15728.
Esta vulnerabilidad permite a atacantes adyacentes a la red ejecutar código arbitrario en los routers D-Link DIR-2150 4.0.1 afectados. No se requiere autenticación para aprovechar esta vulnerabilidad. La falla específica existe dentro del servicio anweb, que escucha en los puertos TCP 80 y 443 de forma predeterminada. 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 basado en pila de longitud fija. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto de la raíz. Era ZDI-CAN-15728.
