- Summary
- Insufficient session invalidation in Kanboard
- Details
-
Kanboard is project management software that focuses on the Kanban methodology. In affected versions sessions are still usable even though their lifetime has exceeded. Kanboard implements a cutom session handler (
app/Core/Session/SessionHandler.php), to store the session data in a database. Therefore, when asession_idis given, kanboard queries the data from thesessionssql table. At this point, it does not correctly verify, if a givensession_idhas already exceeded its lifetime (expires_at). Thus, a session which's lifetime is already> time(), is still queried from the database and hence a valid login. The implemented SessionHandlerInterface::gc function, that does remove invalid sessions, is called only with a certain probability (Cleans up expired sessions. Called bysession_start(), based onsession.gc_divisor,session.gc_probabilityandsession.gc_maxlifetimesettings) accordingly to the php documentation. In the official Kanboard docker image these values default to: session.gcprobability=1, session.gcdivisor=1000. Thus, an expired session is only terminated with probability 1/1000. This issue has been addressed in release 1.2.43 and all users are advised to upgrade. There are no known workarounds for this vulnerability. - Database specific
