Descriptions

An issue was discovered in Symfony before 2.7.38, 2.8.31, 3.2.14, 3.3.13, 3.4-BETA5, and 4.0-BETA5. The current implementation of CSRF protection in Symfony (Version >=2) does not use different tokens for HTTP and HTTPS; therefore the token is subject to MITM attacks on HTTP and can then be used in an HTTPS context to do CSRF attacks.

Se ha descubierto un problema en Symfony en versiones anteriores a la 2.7.38, 2.8.31, 3.2.14, 3.3.13, 3.4-BETA5 y 4.0-BETA5. La implementación actual de la protección CSRF en Symfony (versiones a partir de la 2) no emplea tokens diferentes para HTTP y HTTPS; por lo tanto, el token es vulnerable a ataques Man-in-the-Middle (MitM) en HTTP y puede emplearse en un contexto HTTPS para realizar ataques Cross-Site Request Forgery (CSRF).
