Red Hat Security Advisory: JBoss Enterprise Application Platform 5.2.0 update Security Advisory secalert@redhat.com Red Hat Security Response Team RHSA-2013:0194 Final 1 1 2013-01-24T18:06:00Z Current version 2013-01-24T18:06:00Z 2013-01-24T18:06:00Z Red Hat rhsa-to-cvrf 1.0.1484 2013-01-30T12:59:02Z JBoss Enterprise Application Platform 5.2.0, which fixes multiple security issues, various bugs, and adds several 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. This JBoss Enterprise Application Platform 5.2.0 release serves as a replacement for JBoss Enterprise Application Platform 5.1.2, and includes bug fixes and enhancements. Refer to the JBoss Enterprise Application Platform 5.2.0 Release Notes for information on the most significant of these changes. The Release Notes will be available shortly from https://access.redhat.com/knowledge/docs/ An attack technique against the W3C XML Encryption Standard when block ciphers were used in CBC mode could allow a remote attacker to conduct chosen-ciphertext attacks, leading to the recovery of the entire plain text of a particular cryptogram. (CVE-2011-1096) 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. Manual action is required to apply this fix. Refer to the Solution section. (CVE-2011-2730) Apache CXF checked to ensure XML elements were signed or encrypted by a Supporting Token, but not whether the correct token was used. A remote attacker could transmit confidential information without the appropriate security, and potentially circumvent access controls on web services exposed via Apache CXF. Refer to the Solution section for details. (CVE-2012-2379) When an application used FORM authentication, along with another component that calls request.setUserPrincipal() before the call to FormAuthenticator#authenticate() (such as the Single-Sign-On valve), it was possible to bypass the security constraint checks in the FORM authenticator by appending "/j_security_check" to the end of a URL. (CVE-2012-3546) The JMX Console was vulnerable to CSRF attacks, allowing a remote attacker to hijack the authenticated JMX Console session of an administrator. (CVE-2011-2908) An XSS flaw allowed a remote attacker to perform an XSS attack against victims using the JMX Console. (CVE-2011-4575) SecurityAssociation.getCredential() returned the previous credential if no security context was provided. Depending on the deployed applications, this could possibly allow a remote attacker to hijack the credentials of a previously-authenticated user. (CVE-2012-3370) Configuring the JMX Invoker to restrict access to users with specific roles did not actually restrict access, allowing remote attackers with valid JMX Invoker credentials to perform JMX operations accessible to roles they are not a member of. (CVE-2012-5478) twiddle.sh accepted credentials as command line arguments, allowing local users to view them via a process listing. (CVE-2009-5066) The JMXInvokerHAServlet and EJBInvokerHAServlet invoker servlets allow unauthenticated access by default in some profiles. The security interceptor's second layer of authentication prevented direct exploitation of this flaw. If the interceptor was misconfigured or inadvertently disabled, this flaw could lead to arbitrary code execution in the context of the user running the JBoss server. (CVE-2012-0874) The JGroups diagnostics service was enabled with no authentication when a JGroups channel was started, allowing attackers on the adjacent network to read diagnostic information. (CVE-2012-2377) CallerIdentityLoginModule retained the password from the previous call if a null password was provided. In non-default configurations this could possibly lead to a remote attacker hijacking a previously-authenticated user's session. (CVE-2012-3369) Red Hat would like to thank Juraj Somorovsky of Ruhr-University Bochum for reporting CVE-2011-1096 and CVE-2011-2487; the Apache CXF project for reporting CVE-2012-2379; and Tyler Krpata for reporting CVE-2011-4575. CVE-2012-3370 and CVE-2012-3369 were discovered by Carlo de Wolf of Red Hat; CVE-2012-5478 discovered by Derek Horton of Red Hat; CVE-2012-0874 discovered by David Jorm of Red Hat; and CVE-2012-2377 was discovered by Red Hat.

If your system has deployed applications which use Spring framework, the context parameter "springJspExpressionSupport" must be set to "false" to mitigate this flaw, for example, in the application's web.xml file. This will prevent the double-evaluation of EL expressions that led to this flaw. CVE-2012-2379 has been addressed by disabling the affected configuration in this release. If you use the affected configuration, an exception will be thrown and the relevant application will not deploy to the server.
