base score, which gives a detailed severity rating, is available from the

Description

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.
