Red Hat Security Advisory
Synopsis: Moderate: jbossas security update
Advisory ID: RHSA-2012:1013-01
Product: JBoss Enterprise Application Platform
Advisory URL: https://rhn.redhat.com/errata/RHSA-2012-1013.html
Issue date: 2012-06-19
CVE Names: CVE-2012-1167
=====================================================================
1. Summary:
An update for JBoss Enterprise Application Platform 5.1.2 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 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.
2. Description:
The Java Authorization Contract for Containers (Java ACC) specification
defines Permission classes and the binding of container access decisions to
operations on instances of these permission classes. JaccAuthorizationRealm
performs authorization based on Java ACC permissions and a Policy
implementation.
When a JBoss server is configured to use JaccAuthorizationRealm, the
WebPermissionMapping class creates permissions that are not checked and can
permit access to users without checking their roles. If the
ignoreBaseDecision property is set to true on JBossWebRealm, the web
authorization process is handled exclusively by JBossAuthorizationEngine,
without any input from JBoss Web. This allows any valid user to access an
application, without needing to be assigned the role specified in the
application's web.xml "security-constraint" tag. (CVE-2012-1167)
Warning: Before applying this update, back up your JBoss Enterprise
Application Platform's "jboss-as/server/[PROFILE]/deploy/" directory, along
with all other customized configuration files.
All users of JBoss Enterprise Application Platform 5.1.2 as provided from
the Red Hat Customer Portal are advised to install this update.
3. Solution:
The References section of this erratum contains a download link (you must
log in to download the update). Before applying the update, back up your
existing JBoss Enterprise Application Platform installation (including all
applications and configuration files).
The JBoss server process must be restarted for this update to take effect.
4. Bugs fixed (http://bugzilla.redhat.com/):
802622 - CVE-2012-1167 JBoss: authentication bypass when running under JACC with ignoreBaseDecision on JBossWebRealm
