"The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in
the RHSA-2012:1186 advisory.

    Katello allows you to manage the application life-cycle for Linux systems.
    Katello is used by CloudForms System Engine, an Infrastructure as a Service
    (IaaS) application that provides tools to update and monitor systems within
    private and hybrid clouds, and can be used to configure new systems,
    subscribe to updates, and maintain installations in distributed
    environments.

    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 CloudForms System Engine web interface as any user, without
    knowing the passwords. (CVE-2012-3503)

    All users of Red Hat CloudForms are advised to upgrade to these updated
    packages, which correct this issue. For instructions on applying this
    update, refer to the CloudForms Release Notes, linked to in the References
    section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
