Updated JBoss Enterprise Application Platform (JBEAP) 4.2 packages that fix three security issues and multiple bugs are now available for Red Hat Enterprise Linux 4 as JBEAP 4.2.0.CP09. The Red Hat Security Response Team has rated this update as having critical security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.
JBoss Enterprise Application Platform is the market leading platform for innovative and scalable Java applications; integrating the JBoss Application Server, with JBoss Hibernate and JBoss Seam into a complete, simple enterprise solution. This release of JBEAP for Red Hat Enterprise Linux 4 serves as a replacement to JBEAP 4.2.0.CP08. These updated packages include multiple bug fixes which are detailed in the Release Notes. The Release Notes will be available shortly from the link in the References section. The following security issues are also fixed with this release: The JMX Console configuration only specified an authentication requirement for requests that used the GET and POST HTTP "verbs". A remote attacker could create an HTTP request that does not specify GET or POST, causing it to be executed by the default GET handler without authentication. This release contains a JMX Console with an updated configuration that no longer specifies the HTTP verbs. This means that the authentication requirement is applied to all requests. (CVE-2010-0738) For the CVE-2010-0738 issue, if an immediate upgrade is not possible or the server deployment has been customized, a manual fix can be applied. Refer to the "Security" subsection of the "Issues fixed in this release" section (JBPAPP-3952) of the JBEAP Release Notes, linked to in the References, for details. Contact Red Hat JBoss Support for advice before making the changes noted in the Release Notes. Red Hat would like to thank Stefano Di Paola and Giorgio Fedon of Minded Security for responsibly reporting the CVE-2010-0738 issue. Unauthenticated access to the JBoss Application Server Web Console (/web-console) is blocked by default. However, it was found that this block was incomplete, and only blocked GET and POST HTTP verbs. A remote attacker could use this flaw to gain access to sensitive information. This release contains a Web Console with an updated configuration that now blocks all unauthenticated access to it by default. (CVE-2010-1428) The RHSA-2008:0825 update fixed an issue (CVE-2008-3273) where unauthenticated users were able to access the status servlet; however, a bug fix included in the RHSA-2009:0346 update re-introduced the issue. A remote attacker could use this flaw to acquire details about deployed web contexts. (CVE-2010-1429) Warning: Before applying this update, please backup the JBEAP "server/[configuration]/deploy/" directory, and any other customized configuration files. All users of JBEAP 4.2 on Red Hat Enterprise Linux 4 are advised to upgrade to these updated packages.
