"value": "NETGEAR RAX30 Telnet CLI passwd 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. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed.\n\nThe specific flaw exists within the telnet CLI service, which listens on TCP port 23. 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-20009."

"value": "NETGEAR RAX30 Telnet CLI passwd Vulnerabilidad de ejecuci\u00f3n remota de c\u00f3digo de desbordamiento de b\u00fafer en la regi\u00f3n stack de la memoria. Esta vulnerabilidad permite a atacantes adyacentes a la red ejecutar c\u00f3digo arbitrario en instalaciones afectadas de enrutadores NETGEAR RAX30. Aunque se requiere autenticaci\u00f3n para aprovechar esta vulnerabilidad, se puede omitir el mecanismo de autenticaci\u00f3n existente. La falla espec\u00edfica existe dentro del servicio CLI de telnet, que escucha en el puerto TCP 23. El problema se debe a la falta de una validaci\u00f3n adecuada de la longitud de los datos proporcionados por el usuario antes de copiarlos en un b\u00fafer basado en pila de longitud fija. Un atacante puede aprovechar esta vulnerabilidad para ejecutar c\u00f3digo en el contexto de la ra\u00edz. Fue ZDI-CAN-20009."
