RHSA-2012:1060 - Security Advisory

Topic

An updated cobbler package that fixes one security issue is now available
for Red Hat Network Satellite 5.4.

The Red Hat Security Response Team has rated this update as having moderate
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

Cobbler is a network install server. Cobbler supports PXE, virtualized
installs, and re-installing existing Linux machines.

A command injection flaw was found in Cobbler's power management XML-RPC
method. A remote, authenticated user who is permitted to perform Cobbler
configuration changes via the Cobbler XML-RPC API, could use this flaw to
execute arbitrary code with root privileges on the Red Hat Network
Satellite server. (CVE-2012-2395)

Note: Red Hat Network Satellite uses a special user account to configure
Cobbler. By default, only this account is permitted to perform Cobbler
configuration changes, and the credentials for the account are only
accessible to the Satellite host's administrator. As such, this issue only
affected environments where the administrator allowed other users to make
Cobbler configuration changes.

Users of Red Hat Network Satellite 5.4 are advised to upgrade to this
updated cobbler package, which contains a backported patch to correct this
issue. Red Hat Network Satellite must be restarted
("/usr/sbin/rhn-satellite restart") for this update to take effect.
