A flaw was found in the way JBoss RichFaces handled deserialization. A remote attacker could use this flaw to trigger the execution of the deserialization methods in any serializable class deployed on the server. This could lead to a variety of security impacts depending on the deserialization logic of these classes.

Red Hat JBoss Operations Network (JON) before 2.4.2 and 3.0.x before 3.0.1 allows remote attackers to hijack agent sessions via an agent registration request without a security token.

Multiple cross-site scripting (XSS) flaws were found in the JON administration interface. If a remote attacker could trick a user, who was logged into the JON administration interface, into visiting a specially-crafted URL, it would lead to arbitrary web script execution in the context of the user's JON session.
