Versions 4.6.0 and below contain a Server-Side Request Forgery (SSRF) vulnerability in the subscription and payment logo/icon upload functionality. The application validates the IP address of the provided URL before making the request, but allows HTTP redirects (CURLOPT_FOLLOWLOCATION = true), enabling an attacker to bypass the IP validation and access internal resources, including cloud instance metadata endpoints. The getLogoFromUrl() function validates the URL by resolving the hostname and checking if the resulting IP is in a private or reserved range using FILTER_FLAG_NO_PRIV_RANGE | FILTER_FLAG_NO_RES_RANGE. However, the subsequent cURL request is configured with CURLOPT_FOLLOWLOCATION = true and CURLOPT_MAXREDIRS = 3, which means the request will follow HTTP redirects without re-validating the destination IP. This issue has been fixed in version 4.6.1."},{"lang":"es","value":"Wallos es un rastreador de suscripciones personal de código abierto y autoalojable. Versiones 4.6.0 e inferiores contienen una vulnerabilidad de falsificación de petición del lado del servidor (SSRF) en la funcionalidad de carga de logotipos/iconos de suscripción y pago. La aplicación valida la dirección IP de la URL proporcionada antes de realizar la petición, pero permite redirecciones HTTP (CURLOPT_FOLLOWLOCATION = true), lo que permite a un atacante eludir la validación de IP y acceder a recursos internos, incluyendo puntos finales de metadatos de instancias en la nube. La función getLogoFromUrl() valida la URL resolviendo el nombre de host y comprobando si la dirección IP resultante está en un rango privado o reservado usando FILTER_FLAG_NO_PRIV_RANGE | FILTER_FLAG_NO_RES_RANGE. Sin embargo, la petición cURL subsiguiente está configurada con CURLOPT_FOLLOWLOCATION = true y CURLOPT_MAXREDIRS = 3, lo que significa que la petición seguirá las redirecciones HTTP sin revalidar la dirección IP de destino.
