Descriptions
NETGEAR RAX30 rex_cgi JSON Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of NETGEAR RAX30 routers. Authentication is required to exploit this vulnerability. The specific flaw exists within the handling of JSON data. 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-19355.
NETGEAR RAX30 rex_cgi Vulnerabilidad de ejecución remota de código de desbordamiento de búfer en la región stack de la memoria de análisis JSON. Esta vulnerabilidad permite a atacantes adyacentes a la red ejecutar código arbitrario en instalaciones afectadas de enrutadores NETGEAR RAX30. Se requiere autenticación para aprovechar esta vulnerabilidad. La falla específica existe en el manejo de datos JSON. 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-19355.
