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.
