CVE-2017-16652
First published: Thu Nov 16 2017(Updated: )
An issue was discovered in Symfony 2.7.x before 2.7.38, 2.8.x before 2.8.31, 3.2.x before 3.2.14, and 3.3.x before 3.3.13. `DefaultAuthenticationSuccessHandler` or `DefaultAuthenticationFailureHandler` takes the content of the `_target_path` parameter and generates a redirect response, but no check is performed on the path, which could be an absolute URL to an external domain. This Open redirect vulnerability can be exploited for example to mount effective phishing attacks.
