Several vulnerabilities were reported in Red Hat Network Satellite Server. A remote user can conduct cross-site scripting attacks.|
Several scripts do not properly filter HTML code from user-supplied input before displaying the input [CVE-2011-2919, CVE-2011-2920, CVE-2011-2927, CVE-2011-3344]. A remote user can create a specially crafted URL that, when loaded by a target user, will cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the site running the Red Hat Network Satellite Server software and will run in the security context of that site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.
The web interface login page contains an open redirect flaw. A remote user can create a specially crafted URL for the login page that, when loaded by a target user, will redirect the target user to an arbitrary page [CVE-2011-1594].
Daniel Karanja Muturi, Nils Juenemann, The Bearded Warriors, Sylvain Maes, and Thomas Biege of the SuSE Security Team reported these vulnerabilities.

Red Hat Security Advisory
Synopsis: Moderate: Red Hat Network Satellite server security and enhancement update
Advisory ID: RHSA-2011:1299-01
Product: Red Hat Network Satellite Server
Advisory URL: https://rhn.redhat.com/errata/RHSA-2011-1299.html
Issue date: 2011-09-15
CVE Names: CVE-2011-1594 CVE-2011-2919 CVE-2011-2920
Updated packages that fix several security issues and add one enhancement
are now available for Red Hat Network Satellite 5.4.1 for Red Hat
Enterprise Linux 5 and 6.
The Red Hat Security Response Team has rated this update as having moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.
2. Relevant releases/architectures:
Red Hat Network Satellite Server 5.4 (RHEL v.5) - noarch
Red Hat Network Satellite Server 5.4 (RHEL v.6) - noarch
Red Hat Network (RHN) Satellite provides a solution to organizations
requiring absolute control over and privacy of the maintenance and package
deployment of their servers. It allows organizations to utilize the
benefits of the Red Hat Network without having to provide public Internet
access to their servers or other client systems.
Multiple cross-site scripting (XSS) flaws were found in the RHN Satellite
web interface. A remote attacker could use these flaws to perform a
cross-site scripting attack against victims using the RHN Satellite web
interface. (CVE-2011-2919, CVE-2011-2920, CVE-2011-2927, CVE-2011-3344)
An open redirect flaw was found in the RHN Satellite web interface login
page. A remote attacker able to trick a victim to open the login page using
a specially-crafted link could redirect the victim to an arbitrary page
after they successfully log in. (CVE-2011-1594)
Red Hat would like to thank Daniel Karanja Muturi for reporting
CVE-2011-2919; Nils Juenemann and The Bearded Warriors for independently
reporting CVE-2011-2920; Nils Juenemann for reporting CVE-2011-2927;
Sylvain Maes for reporting CVE-2011-3344; and Thomas Biege of the SuSE
Security Team for reporting CVE-2011-1594.
This update also adds the following enhancement:
* Session cookies set by RHN Satellite are now marked as HTTPOnly. This
setting helps reduce the impact of cross-site scripting flaws by
instructing the browser to disallow scripts access to those cookies.
Users of Red Hat Network Satellite 5.4.1 are advised to upgrade to these
updated packages, which contain patches to correct these issues and add
this enhancement. For this update to take effect, Red Hat Network Satellite
must be restarted. Refer to the Solution section for details.
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
Run the following command to restart the Red Hat Network Satellite
# rhn-satellite restart
