      "value": "A buffer overflow vulnerability exists in the TOTOLINK A950RG Router firmware V5.9c.4592_B20191022_ALL within the `global.so` binary. The `getSaveConfig` function retrieves the `http_host` parameter from user input via `websGetVar` and copies it into a fixed-size stack buffer (`v13`) using `strcpy()` without performing any length checks. An unauthenticated remote attacker can exploit this vulnerability by sending a specially crafted HTTP request to the router's web interface, potentially leading to arbitrary code execution."

      "value": "Existe una vulnerabilidad de desbordamiento de búfer en el firmware del router TOTOLINK A950RG V5.9c.4592_B20191022_ALL dentro del binario “global.so”. La función “getSaveConfig” recupera el parámetro “http_host” de la entrada del usuario a través de “websGetVar” y lo copia en un búfer de pila de tamaño fijo (“v13”) usando “strcpy()” sin realizar ninguna comprobación de longitud. Un atacante remoto no autenticado puede explotar esta vulnerabilidad enviando una solicitud HTTP especialmente diseñada a la interfaz web del router, lo que podría conducir a la ejecución de código arbitrario."
