Luci in Red Hat Conga does not properly enforce the user session timeout, which might allow attackers to gain access to the session by reading the ac session cookie. NOTE: this issue has been SPLIT due to different vulnerability types. Use CVE-2012-3359 for the base64-encoded storage of the user and password in a cookie.

It was reported that Luci's (Luci is a web based front-end component of the Conga cluster management system) user session timeout feature depended only on JavaScript script running in the user's browser. If user closed browser tab without logging out of Luci session and without closing browser, they could re-open Luci web interface and continue using the session even after the timeout period has elapsed.
