Description

Katello allows you to manage the application life-cycle for Linux systems.
Katello is used by Red Hat Subscription Asset Manager, a distributor
application for handling subscription information and software updates on
client machines.

It was found that the katello-common package's installation script did not
correctly generate the secret token used for session cookie generation,
leading to every default installation using the same secret token. A remote
attacker could use this flaw to create a cookie that would allow them to
log into the Subscription Asset Manager web interface as any user, without
knowing the passwords. (CVE-2012-3503)
