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 Enterprise Web Platform is for mid-size workloads, focusing on light and rich Java applications. Web Platform is a slimmed down profile of the JBoss Enterprise Application Platform.
This JBoss Enterprise Web Platform 5.1.1 release for Red Hat Enterprise Linux 4, 5, and 6 serves as a replacement for JBoss Enterprise Web Platform 5.1.0.
These updated packages include the bug fixes detailed in the release notes, which are linked to from the References section of this erratum.
The following security issue is also fixed with this release:
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.
Warning: Before applying this update, please back up your JBoss Enterprise Web Platform's "jboss-as-web/server/[PROFILE]/deploy/" directory and any other customized configuration files.
All users of JBoss Enterprise Web Platform on Red Hat Enterprise Linux 4, 5, and 6 are advised to upgrade to these updated packages. Manual action is required for this update to take effect. Refer to the Solution section for details.
