In Jboss Application Server as shipped with Red Hat Enterprise Application Platform 5.2, it was found that the doFilter method in the ReadOnlyAccessFilter of the HTTP Invoker does not restrict classes for which it performs deserialization and thus allowing an attacker to execute arbitrary code via crafted serialized data.

A vulnerability was found in Hibernate-Validator. The SafeHtml validator annotation fails to properly sanitize payloads consisting of potentially malicious code in HTML comments and instructions. This vulnerability can result in an XSS attack.

jmx-remoting.sar in JBoss Remoting, as used in Red Hat JBoss Enterprise Application Platform (JEAP) 5.2.0, Red Hat JBoss BRMS 5.3.1, Red Hat JBoss Portal Platform 5.2.2, and Red Hat JBoss SOA Platform 5.3.1, does not properly implement the JSR 160 specification, which allows remote attackers to execute arbitrary code via unspecified vectors.

The EJB invocation handler implementation in Red Hat JBossWS, as used in JBoss Enterprise Application Platform (EAP) before 6.2.0, does not properly enforce the method level restrictions for JAX-WS Service endpoints, which allows remote authenticated users to access otherwise restricted JAX-WS handlers by leveraging permissions to the EJB class.

Red Hat JBoss Enterprise Application Platform (EAP) before 6.1.0 and JBoss Portal before 6.1.0 does not load the implementation of a custom authorization module for a new application when an implementation is already loaded and the modules share class names, which allows local users to control certain applications' authorization decisions via a crafted application.

PicketBox, as used in Red Hat JBoss Enterprise Application Platform before 6.1.1, allows local users to obtain the admin encryption key by reading the Vault data file.

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.

The processInvocation function in org.jboss.as.ejb3.security.AuthorizationInterceptor in JBoss Enterprise Application Platform (aka JBoss EAP or JBEAP) before 6.0.1, authorizes all requests when no roles are allowed for an Enterprise Java Beans (EJB) method invocation, which allows attackers to bypass intended access restrictions for EJB methods.
