ResourceBuilderImpl.java in the RichFaces 3.x through 5.x implementation in Red Hat JBoss Web Framework Kit before 2.3.0, Red Hat JBoss Web Platform through 5.2.0, Red Hat JBoss Enterprise Application Platform through 4.3.0 CP10 and 5.x through 5.2.0, Red Hat JBoss BRMS through 5.3.1, Red Hat JBoss SOA Platform through 4.3.0 CP05 and 5.x through 5.3.1, Red Hat JBoss Portal through 4.3 CP07 and 5.x through 5.2.2, and Red Hat JBoss Operations Network through 2.4.2 and 3.x through 3.1.2 does not restrict the classes for which deserialization methods can be called, which allows remote attackers to execute arbitrary code via crafted serialized data.

JGroups diagnostics service in JBoss Enterprise Portal Platform before 5.2.2, SOA Platform before 5.3.0, and BRMS Platform before 5.3.0, is enabled without authentication when started by the JGroups channel, which allows remote attackers in adjacent networks to read diagnostics information via a crafted IP multicast.

The JBoss Server in JBoss Enterprise Application Platform 5.1.x before 5.1.2 and 5.2.x before 5.2.2, Web Platform before 5.1.2, BRMS Platform before 5.3.0, and SOA Platform before 5.3.0, when the server is configured to use the JaccAuthorizationRealm and the ignoreBaseDecision property is set to true on the JBossWebRealm, does not properly check the permissions created by the WebPermissionMapping class, which allows remote authenticated users to access arbitrary applications.
