Advisory URL: https://rhn.redhat.com/errata/RHSA-2011-0462.html
Issue date: 2011-04-20
CVE Names: CVE-2011-1484
An updated jboss-seam.jar file for JBoss Enterprise Application Platform
4.3.0.CP09 and 5.1.0 that fixes one security issue is now available from
the Red Hat Customer Portal.
The Red Hat Security Response Team has rated this update as having
important security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from the
CVE link in the References section.
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)
