CVE-2014-7851
First published: Tue Nov 18 2014(Updated: )
It was reported that oVirt 3.2.2 and later did not correctly terminate sessions when a user logged out from the web interface (there are two sessions used between the browser and the backend: the engine and the restapi). Upon logout, only the engine session was invalidated but the restapi session persisted. If an attacker could obtain that session data and login with their own credentials, they could replace their session token with the stolen token and elevate their privileges to that of victim user. Note that in order for this to be exploited, the attacker must also have a valid login and authenticate successfully.
