Summary
Red Hat Security Advisory: Red Hat JBoss Portal 5.2.2 security update

Notes

Topic
Red Hat JBoss Portal 5.2.2 roll up patch 1, which fixes multiple security issues 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. 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.
Details
Red Hat JBoss Portal is the open source implementation of the Java EE suite of services and Portal services running atop Red Hat JBoss Enterprise Application Platform. JBoss Web Services leaked side-channel data when distributing symmetric keys (for XML encryption), allowing a remote attacker to recover the entire plain text form of a symmetric key. (CVE-2011-2487) Spring framework could possibly evaluate Expression Language (EL) expressions twice, allowing a remote attacker to execute arbitrary code in the context of the application server, or to obtain sensitive information from the server. (CVE-2011-2730) Note: Manual action is required to apply the fix for CVE-2011-2730. If your system has deployed applications which use Spring framework, the context parameter "springJspExpressionSupport" must be set to "false" to mitigate CVE-2011-2730, for example, in the application's web.xml file. This will prevent the double-evaluation of EL expressions that leads to the flaw. Red Hat JBoss Portal will deploy an application using Spring framework if JOSSO (Java Open Single Sign-On) is configured. 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 only affected the JBoss Web Services Native (jbossws-native) stack as Red Hat JBoss Portal does not use JBoss Web Services CXF (jbossws-cxf). (CVE-2012-5575) For jbossws-native, the fix for CVE-2012-5575 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 Juraj Somorovsky of Ruhr-University Bochum for reporting CVE-2011-2487, and Tibor Jager, Kenneth G. Paterson and Juraj Somorovsky of Ruhr-University Bochum for reporting CVE-2012-5575. Warning: Before applying this update, back up all applications deployed on Red Hat JBoss Portal, along with all customized configuration files, and any databases and database settings. All users of Red Hat JBoss Portal 5.2.2 as provided from the Red Hat Customer Portal are advised to apply this roll up patch.
