CVE-2014-7851
Description
It was found that oVirt did not correctly terminate sessions when a user logged out from the web interface. Upon logout, only the engine session was invalidated but the restapi session persisted. An attacker able to obtain the session data, and able to log in with their own credentials, could replace their session token with the stolen token and elevate their privileges to those of the victim user. Note that in order for this flaw to be exploited, the attacker must also have a valid login and authenticate successfully.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
