Descriptions

TP-Link Omada ER605 Comexe DDNS Response Handling Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of TP-Link Omada ER605 routers. Authentication is not required to exploit this vulnerability. However, devices are vulnerable only if configured to use the Comexe DDNS service.

The specific flaw exists within the handling of DNS responses. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-22383.

TP-Link Omada ER605 Comexe DDNS Manejo de respuesta Vulnerabilidad de ejecución remota de código de desbordamiento de búfer basado en montón. Esta vulnerabilidad permite a atacantes adyacentes a la red ejecutar código arbitrario en las instalaciones afectadas de los enrutadores TP-Link Omada ER605. No se requiere autenticación para aprovechar esta vulnerabilidad. Sin embargo, los dispositivos son vulnerables sólo si están configurados para utilizar el servicio DDNS de Comexe. La falla específica existe en el manejo de respuestas DNS. 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 montón de longitud fija. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto de la raíz. Era ZDI-CAN-22383.
