CVE-2023-27332

Vulnerabilidad de ejecución remota de código de desbordamiento de búfer en la región stack de la memoria de registro de TP-Link Archer AX21 tdpServer. Esta vulnerabilidad permite a atacantes adyacentes a la red ejecutar código arbitrario en las instalaciones afectadas de los enrutadores TP-Link Archer AX21. No se requiere autenticación para aprovechar esta vulnerabilidad. La falla específica existe dentro de la funcionalidad de registro del programa tdpServer, que escucha en el puerto UDP 20002. 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-19898.

TP-Link Archer AX21 tdpServer Logging Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of TP-Link Archer AX21 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the logging functionality of the tdpServer program, which listens on UDP port 20002. 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.
