Summary
Red Hat Security Advisory: Red Hat JBoss SOA Platform 5.3.1 update

Notes

Topic
Red Hat JBoss SOA Platform 5.3.1 roll up patch 2, which fixes one security issue and various bugs, 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.
Details
Red Hat JBoss SOA Platform is the next-generation ESB and business process automation infrastructure. Red Hat JBoss SOA Platform allows IT to leverage existing (MoM and EAI), modern (SOA and BPM-Rules), and future (EDA and CEP) integration methodologies to dramatically improve business process execution speed and quality. This roll up patch serves as a cumulative upgrade for Red Hat JBoss SOA Platform 5.3.1. It includes various bug fixes. The following security issue is also fixed with this release: XML encryption backwards compatibility attacks were found against various frameworks, including Apache CXF. An attacker could force a server to use insecure, legacy cryptosystems, even when secure cryptosystems were enabled on endpoints. By forcing the use of legacy cryptosystems, flaws such as CVE-2011-1096 and CVE-2011-2487 would be exposed, allowing plain text to be recovered from cryptograms and symmetric keys. This issue affected both the JBoss Web Services CXF (jbossws-cxf) and JBoss Web Services Native (jbossws-native) stacks. (CVE-2012-5575) If you are using jbossws-cxf, then automatic checks to prevent this flaw are only run when WS-SecurityPolicy is used to enforce security requirements. It is best practice to use WS-SecurityPolicy to enforce security requirements. To enable WS-Security with this update, you must use the global 'war-security domain="JBossWS"' configuration directive at the beginning of the jboss-esb.xml file. Refer to the update's instructions in the Customer Portal for further information. If you are using jbossws-native, the fix for this flaw is implemented by two new configuration parameters in the 'encryption' element. This element can be a child of 'requires' in both client and server wsse configuration descriptors (set on a per-application basis via the application's jboss-wsse-server.xml and jboss-wsse-client.xml files). The new attributes are 'algorithms' and 'keyWrapAlgorithms'. These attributes should contain a blank space or comma separated list of algorithm IDs that are allowed for the encrypted incoming message, both for encryption and private key wrapping. For backwards compatibility, no algorithm checks are performed by default for empty lists or missing attributes. For example (do not include the line break in your configuration): encryption algorithms="aes-192-gcm aes-256-gcm" keyWrapAlgorithms="rsa_oaep" Specifies that incoming messages are required to be encrypted, and that the only permitted encryption algorithms are AES-192 and 256 in GCM mode, and RSA-OAEP only for key wrapping. Before performing any decryption, the jbossws-native stack will verify that each algorithm specified in the incoming messages is included in the allowed algorithms lists from these new encryption element attributes. The algorithm values to be used for 'algorithms' and 'keyWrapAlgorithms' are the same as for 'algorithm' and 'keyWrapAlgorithm' in the 'encrypt' element. Red Hat would like to thank Tibor Jager, Kenneth G. Paterson and Juraj Somorovsky of Ruhr-University Bochum for reporting this issue. Warning: Before applying the update, back up your existing Red Hat JBoss SOA Platform installation (including its databases, applications, configuration files, and so on). All users of Red Hat JBoss SOA Platform 5.3.1 as provided from the Red Hat Customer Portal are advised to apply this roll up patch.
