Description

JBoss Enterprise BRMS Platform is a business rules management system for
the management, storage, creation, modification, and deployment of JBoss
Rules.

This roll up patch serves as a cumulative upgrade for JBoss Enterprise BRMS
Platform 5.3.1. It includes various bug fixes. The following security
issues are also fixed with this release:

If web services were deployed using Apache CXF with the WSS4JInInterceptor
enabled to apply WS-Security processing, HTTP GET requests to these
services were always granted access, without applying authentication
checks. The URIMappingInterceptor is a legacy mechanism for allowing
REST-like access (via GET requests) to simple SOAP services. A remote
attacker could use this flaw to access the REST-like interface of a simple
SOAP service using GET requests that bypass the security constraints
applied by WSS4JInInterceptor. This flaw was only exploitable if
WSS4JInInterceptor was used to apply WS-Security processing. Services that
use WS-SecurityPolicy to apply security were not affected. (CVE-2012-5633)

It was found that Apache CXF was vulnerable to SOAPAction spoofing attacks
under certain conditions. If web services were exposed via Apache CXF that
use a unique SOAPAction for each service operation, then a remote attacker
could perform SOAPAction spoofing to call a forbidden operation if it
accepts the same parameters as an allowed operation. WS-Policy validation
was performed against the operation being invoked, and an attack must pass
validation to be successful. (CVE-2012-3451)

Red Hat would like to thank the Apache CXF project for reporting the
CVE-2012-3451 issue.
