Summary
authentik is an open-source identity provider. A vulnerability that exists in versions prior to 2024.8.3 and 2024.6.5 allows bypassing password login by adding X-Forwarded-For header with an unparsable IP address, e.g. `a`. This results in a possibility of logging into any account with a known login or email address. The vulnerability requires the authentik instance to trust X-Forwarded-For header provided by the attacker, thus it is not reproducible from external hosts on a properly configured environment. The issue occurs due to the password stage having a policy bound to it, which skips the password stage if the Identification stage is setup to also contain a password stage. Due to the invalid X-Forwarded-For header, which does not get validated to be an IP Address early enough, the exception happens later and the policy fails. The default blueprint doesn't correctly set `failure_result` to `True` on the policy binding meaning that due to this exception the policy returns false and the password stage is skipped. Versions 2024.8.3 and 2024.6.5 fix this issue.

      "value": "authentik es un proveedor de identidad de c\u00f3digo abierto. Una vulnerabilidad que existe en versiones anteriores a 2024.8.3 y 2024.6.5 permite omitir el inicio de sesi\u00f3n con contrase\u00f1a agregando el encabezado X-Forwarded-For con una direcci\u00f3n IP que no se puede analizar, por ejemplo, `a`. Esto genera la posibilidad de iniciar sesi\u00f3n en cualquier cuenta con un nombre de usuario o una direcci\u00f3n de correo electr\u00f3nico conocidos. La vulnerabilidad requiere que la instancia de authentik conf\u00ede en el encabezado X-Forwarded-For proporcionado por el atacante, por lo que no es reproducible desde hosts externos en un entorno configurado correctamente. El problema ocurre debido a que la etapa de contrase\u00f1a tiene una pol\u00edtica vinculada a ella, que omite la etapa de contrase\u00f1a si la etapa de identificaci\u00f3n est\u00e1 configurada para contener tambi\u00e9n una etapa de contrase\u00f1a. Debido al encabezado X-Forwarded-For no v\u00e1lido, que no se valida como una direcci\u00f3n IP con la suficiente anticipaci\u00f3n, la excepci\u00f3n ocurre m\u00e1s tarde y la pol\u00edtica falla. El modelo predeterminado no establece correctamente `failure_result` en `True` en el enlace de pol\u00edtica, lo que significa que debido a esta excepci\u00f3n, la pol\u00edtica devuelve falso y se omite la etapa de contrase\u00f1a. Las versiones 2024.8.3 y 2024.6.5 solucionan este problema."
