RHEL 5 / 6 : cobbler (RHSA-2012:1060)

critical Nessus Plugin ID 64047

Synopsis

The remote Red Hat host is missing a security update for cobbler.

Description

The remote Redhat Enterprise Linux 5 / 6 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2012:1060 advisory.

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.

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.

Solution

Update the RHEL cobbler package based on the guidance in RHSA-2012:1060.
