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.
