AuthorizationInterceptor allows JMX operation to proceed despite authorization failure
CVE: CVE-2012-5478
Component: JBoss
Severity: Moderate
Release date: 2012-01-01T00:00:00+00:00

The AuthorizationInterceptor in JBoss Enterprise Application Platform (EAP) before 5.2.0, Web Platform (EWP) before 5.2.0, BRMS Platform before 5.3.1, and SOA Platform before 5.3.1 does not properly restrict access, which allows remote authenticated users to bypass intended role restrictions and perform arbitrary JMX operations via unspecified vectors.


Remediation:
Note: Manual action is required to apply the fix for CVE-2011-2730. If your
system has deployed applications which use Spring framework, the context
parameter "springJspExpressionSupport" must be set to "false" to mitigate
this flaw, for example, in the application's web.xml file. This will
prevent the double-evaluation of EL expressions that led to this flaw.

CVE-2012-2379 has been addressed by disabling the affected configuration in
this release. If you use the affected configuration, an exception will be
thrown and the relevant application will not deploy to the server. A patch
that allows the affected configuration to be used without this
vulnerability is available in JBoss Enterprise Application Platform 6.0.1.

Warning: Before applying this update, back up your existing JBoss
Enterprise Application Platform installation (including all applications
and configuration files).

All users of JBoss Enterprise Application Platform 5.1.2 on Red Hat
Enterprise Linux 4 are advised to upgrade to these updated packages. The
JBoss server process must be restarted for the update to take effect.

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
