An issue was discovered in Mahara before 15.04.14, 16.x before 16.04.8, 16.10.x before 16.10.5, and 17.x before 17.04.3. When one closes the browser without logging out of Mahara, the value in the usr_session table is not removed. If someone were to open a browser, visit the Mahara site, and adjust the mahara cookie to the old value, they can get access to the users account.

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.
