An issue exists in PHP-Fusion 9.03.50 where session cookies are not deleted once a user logs out, allowing for an attacker to perform a session replay attack and impersonate the victim user.

Weakness

A capture-replay flaw exists when the design of the product makes it possible for a malicious user to sniff network traffic and bypass authentication by replaying it to the server in question to the same effect as the original message (or with minor changes).
