Descriptions

Symfony is a PHP framework for web and console applications and a set of reusable PHP components. A vulnerability related to firewall authentication is in Symfony starting with version 5.3.0 and prior to 5.3.2. When an application defines multiple firewalls, the token authenticated by one of the firewalls was available for all other firewalls. This could be abused when the application defines different providers for each part of the application, in such a situation, a user authenticated on a part of the application could be considered authenticated on the rest of the application. Starting in version 5.3.2, a patch ensures that the authenticated token is only available for the firewall that generates it.

Una vulnerabilidad relacionada con la autenticación del firewall se presenta en Symfony a partir de versión 5.3.0 y anteriores a 5.3.2. Cuando una aplicación define múltiples firewalls, el token autenticado por uno de los firewalls estaba disponible para todos los otros firewalls. Esto podría ser abusado cuando la aplicación define diferentes proveedores para cada parte de la aplicación, en tal situación, un usuario autenticado en una parte de la aplicación podría ser considerado autenticado en el resto de la aplicación. A partir de versión 5.3.2, un parche asegura que el token autenticado sólo está disponible para el firewall que lo genera
