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.
Users of jboss-seam2 should upgrade to these updated packages, which
correct this issue. Manual action is required for this update to take
effect. Refer to the Solution section for details.
