Descriptions

Symfony is a PHP framework for web and console applications and a set of reusable PHP components. When authenticating users Symfony by default regenerates the session ID upon login, but preserves the rest of session attributes. Because this does not clear CSRF tokens upon login, this might enables same-site attackers to bypass the CSRF protection mechanism by performing an attack similar to a session-fixation. This issue has been fixed in the 4.4 branch.

Soner Sayakci discovered that Symfony incorrectly handled cookie storage in the web cache. An attacker could possibly use this issue to obtain sensitive information and access unauthorized resources. Marco Squarcina discovered that Symfony incorrectly handled the storage of user session information. An attacker could possibly use this issue to perform a cross-site request forgery attack. Pierre Rudloff discovered that Symfony incorrectly checked HTML input. An attacker could possibly use this issue to perform cross site scripting.
