Summary: 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. 2. 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. All users of JBoss Enterprise Application Platform 4.3.0.CP09 and 5.1.0 as provided from the Red Hat Customer Portal are advised to install this update. 3. Solution: The References section of this erratum contains download links (you must log in to download the updated file). Before applying the update, backup your existing JBoss Enterprise Application Platform installation (including all applications and configuration files). Important: JBoss Enterprise Application Platform 4.3.0.CP09 ships with both the JBoss Seam and JBoss Seam 2 frameworks. Ensure you only replace version 2 with the updated jboss-seam.jar file. The JBoss server process must be restarted for the update to take effect. 4.
