Cross-site request forgery (CSRF) vulnerability in the management interface in FreeIPA before 2.1.4 allows remote attackers to hijack the authentication of administrators for requests that make configuration changes.

The remote Oracle Linux 6 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2011-1533 advisory.

    - Updated patch for CVE-2011-3636 to include CR in the HTTP headers.
      xmlrpc-c in RHEL-6 doesn't suppose the dont_advertise option so that is       not set any more. Another fake header, X-Original-User_Agent, is added       so there is no more trailing junk after the Referer header.  (#749870)
    - Require an HTTP Referer header to address CSRF attackes. CVE-2011-3636.
      (#749870)

Tenable has extracted the preceding description block directly from the Oracle 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.

This Identity Management Application is a centralized authentication, identity management and authorization solution for both traditional and cloud based enterprise environments. It integrates components of the Upstream Directory Server, MIT Kerberos, the Upstream Certificate System, NTP, and DNS. It provides web browser and command-line interfaces. Its administration tools allow an administrator to quickly install, set up, and administer a group of domain controllers to meet the authentication and identity management requirements of large scale Linux and UNIX deployments.

A Cross-Site Request Forgery (CSRF) flaw was found in this package. If a remote attacker could trick a user, who was logged into the management web interface, into visiting a specially crafted URL, the attacker could perform configuration changes with the privileges of the logged in user. (CVE-2011-3636)

Due to the changes required to fix CVE-2011-3636, client tools will need to be updated for client systems to communicate with updated servers. New client systems will need to have the updated ipa-client package installed to be enrolled. Already enrolled client systems will need to have the updated certmonger package installed to be able to renew their system certificate. Note that system certificates are valid for two years by default.

This update includes several bug fixes. Space precludes documenting all of these changes in this advisory.

Users of this software should upgrade to these updated packages, which correct these issues.

A number of additional packages were added to the security repository so that this package could be installed on older SL systems.

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2011:1533 advisory.
