Symfony 2.0.X before 2.0.24, 2.1.X before 2.1.12, 2.2.X before 2.2.5, and 2.3.X before 2.3.3 have an issue in the HttpFoundation component. The Host header can be manipulated by an attacker when the framework is generating an absolute URL. A remote attacker could exploit this vulnerability to inject malicious content into the Web application page and conduct various attacks.
