-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: Red Hat JBoss BPM Suite 6.0.1 update Advisory ID: RHSA-2014:0371-01 Product: Red Hat JBoss BPM Suite Advisory URL: https://rhn.redhat.com/errata/RHSA-2014-0371.html Issue date: 2014-04-03 CVE Names: CVE-2011-5245 CVE-2012-0818 CVE-2013-1624 CVE-2013-6468 CVE-2013-7285 CVE-2014-0002 CVE-2014-0003 ===================================================================== 1. Summary: Red Hat JBoss BPM Suite 6.0.1, which fixes multiple security issues, various bugs, and adds enhancements, is now available from the Red Hat Customer Portal. The Red Hat Security Response Team has rated this update as having Important 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. 2. Description: Red Hat JBoss BPM Suite is a business rules management system for the management, storage, creation, modification, and deployment of JBoss rules. This release of Red Hat JBoss BPM Suite 6.0.1 serves as a replacement for Red Hat JBoss BPM Suite 6.0.0, and includes bug fixes and enhancements. Refer to the Red Hat JBoss BPM Suite 6.0.1 Release Notes for information on the most significant of these changes. The Release Notes will be available at https://access.redhat.com/site/documentation/Red_Hat_JBoss_BPM_Suite/ The following security issues are fixed with this release: It was discovered that JBoss BPM Suite allowed remote authenticated users to submit arbitrary Java code in MVFLEX Expression Language (MVEL) or JBoss Rules expressions, resulting in arbitrary code execution within the security context of the application server. Refer to the Solution section for details on the fix for this issue. (CVE-2013-6468) It was found that XStream could deserialize arbitrary user-supplied XML content, representing objects of any type. A remote attacker able to pass XML to XStream could use this flaw to perform a variety of attacks, including remote code execution in the context of the server running the XStream application. (CVE-2013-7285) It was found that the Apache Camel XSLT component allowed XSL stylesheets to call external Java methods. A remote attacker able to submit messages to a Camel route could use this flaw to perform arbitrary remote code execution in the context of the Camel server process. (CVE-2014-0003) It was found that RESTEasy was vulnerable to XML External Entity (XXE) attacks. If a remote attacker submitted a request containing an external XML entity to a RESTEasy endpoint, the entity would be resolved, allowing the attacker to read files accessible to the user running the application server. This flaw affected DOM (Document Object Model) Document and JAXB (Java Architecture for XML Binding) input. (CVE-2011-5245, CVE-2012-0818) It was discovered that bouncycastle leaked timing information when decrypting TLS/SSL protocol encrypted records when CBC-mode cipher suites were used. A remote attacker could possibly use this flaw to retrieve plain text from the encrypted packets by using a TLS/SSL server as a padding oracle. (CVE-2013-1624) It was found that the Apache Camel XSLT component would resolve entities in XML messages when transforming them using an XSLT route. A remote attacker able to submit messages to an XSLT Camel route could use this flaw to read files accessible to the user running the application server and, potentially, perform other more advanced XML External Entity (XXE) attacks. (CVE-2014-0002) The CVE-2014-0002 and CVE-2014-0003 issues were discovered by David Jorm of the Red Hat Security Response Team, and the CVE-2013-6468 issue was discovered by Marc Schoenefeld of the Red Hat Security Response Team. Red Hat would like to thank Grégory Draperi for independently reporting CVE-2013-6468. All users of Red Hat JBoss BPM Suite 6.0.0 as provided from the Red Hat Customer Portal are advised to upgrade to Red Hat JBoss BPM Suite 6.0.1. 3. Solution: The References section of this erratum contains download links (you must log in to download the updates). Before applying the update, back up your existing installation, including all applications, configuration files, databases and database settings, and so on. It is recommended to halt the server by stopping the JBoss Application Server process before installing this update, and then after installing the update, restart the server by starting the JBoss Application Server process. The fix for CVE-2013-6468 enables the Java Security Manager (JSM) to sandbox the evaluation of MVEL expressions. This introduces performance degradation in high load environments. The following ways of running Red Hat JBoss BPM Suite are considered secure while mitigating performance degradation: 1. In high load environments where performance is critical, it is recommended to only deploy applications that have been developed on other systems and properly reviewed. It is also recommended not to create any users with the Analyst role on such systems. If these safeguards are followed, it is safe to leave JSM disabled on these systems so it does not introduce any performance degradation. 2. In testing and development environments without high loads, or in environments where rule authoring is exposed to external networks, it is recommended to have JSM enabled in order to achieve security benefits of properly sandboxed evaluation of MVEL expressions. Allowing users with the Analyst role to log in to the Business Central console when JSM is disabled is not secure and not recommended. 4.
