CVE-2023-32143
D-Link DAP-1360 webupg UPGCGI_CheckAuth Numeric Truncation Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DAP-1360 routers. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the handling of requests to the /cgi-bin/webupg endpoint. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute code in the context of root. . Was ZDI-CAN-18423.

Esta vulnerabilidad permite a atacantes adyacentes a la red ejecutar código arbitrario en instalaciones afectadas de enrutadores D-Link DAP-1360. No se requiere autenticación para aprovechar esta vulnerabilidad. La falla específica existe en el manejo de solicitudes al endpoint /cgi-bin/webupg. El problema se debe a la falta de validación adecuada de los datos proporcionados por el usuario, lo que puede provocar un desbordamiento de enteros antes de asignar un búfer. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto de la raíz. Era ZDI-CAN-18423."
