Descriptions

An issue was discovered in HttpKernel in Symfony 2.7.0 through 2.7.48, 2.8.0 through 2.8.43, 3.3.0 through 3.3.17, 3.4.0 through 3.4.13, 4.0.0 through 4.0.13, and 4.1.0 through 4.1.2. When using HttpCache, the values of the X-Forwarded-Host headers are implicitly set as trusted while this should be forbidden, leading to potential host header injection.

Se ha descubierto un problema en HttpKernel en Symfony, desde la versión 2.7.0 hasta la 2.7.48, desde la versión 2.8.0 hasta la 2.8.43, desde la versión 3.3.0 hasta la 3.3.17, desde la versión 3.4.0 hasta la 3.4.13, desde la versión 4.0.0 hasta la 4.0.13 y desde la versión 4.1.0 hasta la 4.1.2. Al emplear HttpCache, los valores de las cabeceras X-Forwarded-Host se asignan implícitamente como fiables, aunque debería estar prohibido, lo que conduce a una potencial inyección de cabeceras host.
