Description: The JBoss Seam 2 framework is an application framework for building web applications in Java. It was found that the fix for CVE-2011-1484 was incomplete: JBoss Seam 2 did not block access to all malicious 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-2011-2196) Red Hat would like to thank the ObjectWorks+ Development Team at Nomura Research Institute for reporting this issue.
