CVE-2023-27346

TP-Link AX1800 Firmware Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of TP-Link AX1800 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the parsing of firmware images. 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-19703.

Summary		(es) Vulnerabilidad de ejecución remota de código de desbordamiento de búfer en la región stack de la memoria de análisis de firmware TP-Link AX1800. Esta vulnerabilidad permite a atacantes adyacentes a la red ejecutar código arbitrario en las instalaciones afectadas de los enrutadores TP-Link AX1800. No se requiere autenticación para aprovechar esta vulnerabilidad. La falla específica existe en el análisis de imágenes de firmware. 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-19703.
