      "value": "A stack buffer overflow vulnerability exists in the ToToLink LR1200GB (V9.1.0u.6619_B20230130) and NR1800X (V9.1.0u.6681_B20230703) Router firmware within the cstecgi.cgi binary (setDefResponse function). The binary reads the \"IpAddress\" parameter from a web request and copies it into a fixed-size stack buffer using strcpy() without any length validation. Maliciously crafted input can overflow the buffer, leading to potential arbitrary code execution or memory corruption, without requiring authentication."

El binario lee el parámetro ’IpAddress’ de una solicitud web y lo copia en un búfer de pila de tamaño fijo usando strcpy() sin ninguna validación de longitud. Una entrada creada maliciosamente puede desbordar el búfer, lo que lleva a una potencial ejecución de código arbitrario o corrupción de memoria, sin requerir autenticación."
