Mahara 15.04 before 15.04.7 and 15.10 before 15.10.3 are vulnerable to prevent session IDs from being regenerated on login or logout. This makes users of the site more vulnerable to session fixation attacks.

Weakness

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.

Extended Description

Such a scenario is commonly observed when:

In the generic exploit of session fixation vulnerabilities, an attacker creates a new session on a web application and records the associated session identifier. The attacker then causes the victim to associate, and possibly authenticate, against the server using that session identifier, giving the attacker access to the user’s account through the active session.
