RHSA-2013:0162 - Security Advisory

Topic

An update for JBoss Enterprise SOA Platform 4.2.0.CP05 and 4.3.0.CP05 that
fixes one security issue is now available from the Red Hat Customer Portal.

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 Enterprise SOA Platform is the next-generation ESB and business
process automation infrastructure. JBoss Enterprise SOA Platform allows IT
to leverage existing (MoM and EAI), modern (SOA and BPM-Rules), and future
(EDA and CEP) integration methodologies to dramatically improve business
process execution speed and quality.

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)
