Description

Red Hat JBoss Enterprise Application Platform 6 is a platform for Java applications based on JBoss Application Server 7.

It was found that the Apache commons-collections library permitted code execution when deserializing objects involving a specially constructed chain of classes. A remote attacker could use this flaw to execute arbitrary code with the permissions of the application using the commons-collections library. (CVE-2015-7501)

Further information about the commons-collections flaw may be found at: https://access.redhat.com/solutions/2045023

It was found that JBoss EAP did not properly authorize a user performing a shut down. A remote user with the Monitor, Deployer, or Auditor role could use this flaw to shut down the EAP server, which is an action restricted to admin users. (CVE-2015-5304)

The CVE-2015-5304 issue was discovered by Ladislav Thon of Red Hat Middleware Quality Engineering.
