Topic

An updated rhn-java-sat package that fixes a security issue is now available for
Red Hat Network Satellite 5.2.

The Red Hat Security Response Team has rated this update as having critical
security impact. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available from the CVE link in
the References section.

Description

Red Hat Network Satellite is a systems management tool for Linux-based
infrastructures. It allows for provisioning, monitoring, and remote management
of multiple Linux deployments with a single, centralized tool. The rhn-java-sat
packages contain the code for the Java version of the Red Hat Network Satellite
Web site.

It was found that the web interface provided by Red Hat Network Satellite to
create the initial administrator user was not disabled after the initial user
was created. A remote attacker could use this flaw to create an administrator
user with credentials they specify. This user could then be used to assume
control of the Satellite server. (CVE-2013-4480)

This issue was discovered by Andrew Spurrier of Red Hat.

All rhn-java-sat users are advised to upgrade to this updated package,
which contains a backported patch to correct this issue.
