The JBoss Seam 2 framework is an application framework for building web applications in Java.

It was found that JBoss Seam 2 did not properly block access to JBoss Expression Language (EL) constructs in page exception handling, allowing arbitrary Java methods to be executed. A remote attacker could use this flaw to execute arbitrary code via a specially-crafted URL provided to certain applications based on the JBoss Seam 2 framework. Note: A properly configured and enabled Java Security Manager would prevent exploitation of this flaw. (CVE-2011-1484)

Red Hat would like to thank Martin Kouba from IT SYSTEMS a.s. for reporting this issue.

Users of jboss-seam2 should upgrade to these updated packages, which correct this issue. The JBoss server process must be restarted for this update to take effect.
