Topic

Updated jbossas packages that fix one security issue are now available for
JBoss Enterprise Application Platform 4.3.0 CP10 for Red Hat
Enterprise Linux 4 and 5.

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.

Description

JBoss Web is the web container, based on Apache Tomcat, in JBoss Enterprise
Application Platform. It provides a single deployment platform for the
JavaServer Pages (JSP) and Java Servlet technologies.

It was found that when an application used FORM authentication, along with
another component that calls request.setUserPrincipal() before the call to
FormAuthenticator#authenticate() (such as the Single-Sign-On valve), it was
possible to bypass the security constraint checks in the FORM authenticator
by appending "/j_security_check" to the end of a URL. A remote attacker
with an authenticated session on an affected application could use this
flaw to circumvent authorization controls, and thereby access resources not
permitted by the roles associated with their authenticated session.
(CVE-2012-3546)

Warning: Before applying this update, back up your JBoss Enterprise
Application Platform's "server/[PROFILE]/deploy/" directory, along with all
other customized configuration files.

Users of JBoss Enterprise Application Platform 4.3.0 CP10 on Red Hat
Enterprise Linux 4 and 5 should upgrade to these updated packages, which
correct this issue. The JBoss server process must be restarted for this
update to take effect.

Solution

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
