Cross-site request forgery (CSRF) vulnerability in the JMX Console in Red Hat JBoss Enterprise Application Platform (aka JBoss EAP or JBEAP) 4.3 before 4.3.0.CP09 allows remote attackers to hijack the authentication of administrators for requests that deploy WAR files.

The JBoss EAP 430CP09 security updates for Red Hat Enterprise Linux 4, Red Hat Enterprise Linux 5 and the Customer Support Portal did not, unlike the erratum text stated, provide a fix for CVE-2010-3862, a Denial-of-Service (DoS) flaw in the jboss-remoting component. A missing patch is considered a security regression, and requires a new CVE name. This regression is assigned CVE-2010-4265. It fixes the same issue as CVE-2010-3862 and is specific to JBoss EAP 430CP09.

The org.jboss.remoting.transport.bisocket.BisocketServerInvoker$SecondaryServerSocketThread.run method in JBoss Remoting 2.2.x before 2.2.3.SP4 and 2.5.x before 2.5.3.SP2 in Red Hat JBoss Enterprise Application Platform (aka JBoss EAP or JBEAP) 4.3 through 4.3.0.CP09, and 5.1.0; and JBoss Enterprise Web Platform (aka JBEWP) 5.1.0; allows remote attackers to cause a denial of service (daemon outage) by establishing a bisocket control connection TCP session, and then not sending any application data.
