Descriptions

An issue was discovered in the Security component in Symfony 2.7.x before 2.7.48, 2.8.x before 2.8.41, 3.3.x before 3.3.17, 3.4.x before 3.4.11, and 4.0.x before 4.0.11. By default, a user's session is invalidated when the user is logged out. This behavior can be disabled through the invalidate_session option. In this case, CSRF tokens were not erased during logout which allowed for CSRF token fixation.

Se ha descubierto un problema en el componente Security en Symfony en versiones 2.7.x anteriores a la 2.7.48, versiones 2.8.x anteriores a la 2.8.41, versiones 3.3.x anteriores a la 3.3.17, versiones 3.4.x anteriores a la 3.4.11 y versiones 4.0.x anteriores a la 4.0.11. Por defecto, la sesión de un usuario se invalida cuando el usuario cierra sesión. Este comportamiento puede deshabilitarse mediante la opción invalidate_session. En este caso los tokens CSRF no se eliminaban durante el cierre de sesión, lo que permitía la fijación de tokens CSRF.

Multiple vulnerabilities have been found in the Symfony PHP framework which could lead to open redirects, cross-site request forgery, information disclosure, session fixation or denial of service.
