RHEL 6 : candlepin in Subscription Asset Manager (RHSA-2013:1863)

high Nessus Plugin ID 76187

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated candlepin packages that fix one security issue are now available for Red Hat Subscription Asset Manager.

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

Candlepin is an open source entitlement management system. It tracks the products which an owner has subscribed too, and allows the owner to consume the subscriptions based on configurable business rules.

It was discovered that, by default, Candlepin enabled a very weak authentication scheme if no setting was specified in the configuration file. (CVE-2013-6439)

This issue was discovered by Adrian Likins of Red Hat.

Note: The configuration file as supplied by Subscription Asset Manager 1.2 and 1.3 had this unsafe authentication mode disabled; however, users who have upgraded from Subscription Asset Manager 1.1 or earlier and who have not added 'candlepin.auth.trusted.enable = false' to the Candlepin configuration will be affected by this issue.

Users of Subscription Asset Manager 1.0 or 1.1 who cannot upgrade should add the following to '/etc/candlepin/candlepin.conf' :

candlepin.auth.trusted.enable = false candlepin.auth.trusted.enabled = false

Users of Subscription Asset Manager 1.2 or 1.3 who cannot upgrade should only need to add :

candlepin.auth.trusted.enable = false

Installing this upgrade disables the unsafe authentication scheme unless it is specifically enabled in the configuration.

Users of Red Hat Subscription Asset Manager are advised to upgrade to these updated packages, which correct this issue. Candlepin must be restarted for this update to take effect.

Solution

Update the affected candlepin, candlepin-selinux and / or candlepin-tomcat6 packages.
