Description

The application accepts user-supplied session identifiers and does not regenerate the session ID after authentication. This allows an attacker to predefine a session ID and reuse it after victim authentication, resulting in session takeover.

Session Fixation

Authenticating a user, or otherwise establishing a new user session, without invalidating any existing session identifier gives an attacker the opportunity to steal authenticated sessions.
