CVE-2023-35739

D-Link DAP-2622 DDP Configuration Backup Server IPv6 Address Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DAP-2622 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the DDP service. 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-20066.

Summary		(es) D-Link DAP-2622 Servidor de copia de seguridad de configuración DDP Dirección IPv6 Vulnerabilidad de ejecución remota de código de desbordamiento de búfer en la región stack de la memoria. Esta vulnerabilidad permite a atacantes adyacentes a la red ejecutar código arbitrario en instalaciones afectadas de enrutadores D-Link DAP-2622. No se requiere autenticación para aprovechar esta vulnerabilidad. La falla específica existe dentro del servicio DDP. 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. Fue ZDI-CAN-20066.
