Descriptions

NETGEAR RAX30 soap_serverd Stack-based Buffer Overflow Authentication Bypass Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of NETGEAR RAX30. Authentication is not required to exploit this vulnerability. The specific flaw exists within the soap_serverd binary. When parsing the request headers, the process does not properly validate the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to bypass authentication on the system. Was ZDI-CAN-19840.

NETGEAR RAX30 SOAP_serverd Vulnerabilidad de omisión de autenticación de desbordamiento de búfer basada en pila. Esta vulnerabilidad permite a atacantes adyacentes a la red ejecutar código arbitrario en instalaciones afectadas de NETGEAR RAX30. No se requiere autenticación para aprovechar esta vulnerabilidad. La falla específica existe dentro del binario SOAP_serverd. Al analizar los encabezados de la solicitud, el proceso no valida adecuadamente 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 eludir la autenticación en el sistema. Era ZDI-CAN-19840.
