      "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 (sub_42F32C function). The web interface reads the \"lang\" parameter and constructs Help URL strings using sprintf() into fixed-size stack buffers without proper length validation. Maliciously crafted input can overflow these buffers, potentially leading to arbitrary code execution or memory corruption, without requiring authentication."

La interfaz web lee el parámetro ’lang’ y construye cadenas de URL de ayuda usando sprintf() en búferes de pila de tamaño fijo sin una validación de longitud adecuada. Una entrada creada maliciosamente puede desbordar estos búferes, lo que podría llevar a ejecución de código arbitrario o corrupción de memoria, sin requerir autenticación."
