-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: Red Hat JBoss Portal 6.1.0 update Advisory ID: RHSA-2013:1437-01 Product: Red Hat JBoss Middleware Advisory URL: https://rhn.redhat.com/errata/RHSA-2013-1437.html Issue date: 2013-10-16 CVE Names: CVE-2012-4431 CVE-2012-4529 CVE-2012-4572 CVE-2012-5575 CVE-2013-1921 CVE-2013-2067 CVE-2013-2102 CVE-2013-2160 CVE-2013-2172 CVE-2013-4112 CVE-2013-4128 CVE-2013-4213 ===================================================================== 1. Summary: Red Hat JBoss Portal 6.1.0, 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. 2. Description: This Red Hat JBoss Portal 6.1.0 release serves as a replacement for 6.0.0. Refer to the 6.1.0 Release Notes for further information, available shortly from https://access.redhat.com/knowledge/docs/ It was found that sending a request without a session identifier to a protected resource could bypass the CSRF prevention filter in JBoss Web. A remote attacker could use this flaw to perform CSRF attacks against applications that rely on the CSRF prevention filter. (CVE-2012-4431) When applications used the COOKIE session tracking method, the jsessionid would be appended as a query string parameter when processing the first request of a session. This could possibly lead to users' sessions being hijacked via man-in-the-middle attacks. (CVE-2012-4529) If multiple applications used the same custom authorization module class name, and provided their own implementations of it, the first application to be loaded will have its implementation used for all other applications using the same custom authorization module class name. A local attacker could deploy a malicious application that provides implementations of custom authorization modules that apply authorization rules supplied by the attacker. (CVE-2012-4572) 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. (CVE-2012-5575) Note: Automatic checks to prevent CVE-2012-5575 are only run when WS-SecurityPolicy is used to enforce security requirements, which is best practice. The data file used by PicketBox Vault to store encrypted passwords contains a copy of its own admin key. The file is encrypted using only this admin key, not the corresponding JKS key. A local attacker with permission to read the vault data file could read the admin key from the file. (CVE-2013-1921) A session fixation flaw was found in the Tomcat FormAuthenticator module. (CVE-2013-2067) When a JGroups channel was started, the JGroups diagnostics service was enabled by default with no authentication via IP multicast. An attacker on an adjacent network could exploit this flaw to read diagnostics information. (CVE-2013-2102) Multiple denial of service flaws were found in the way the Apache CXF StAX parser implementation processed certain XML files. A remote attacker could provide a specially crafted XML file that, when processed, would lead to excessive CPU and memory consumption. (CVE-2013-2160) A flaw was found in the way Apache Santuario XML Security for Java validated XML signatures. Santuario allowed a signature to specify an arbitrary canonicalization algorithm, which would be applied to the SignedInfo XML fragment. A remote attacker could exploit this to spoof an XML signature, via a specially-crafted XML signature block. (CVE-2013-2172) A flaw was found in JGroup's DiagnosticsHandler that allowed an attacker on an adjacent network to reuse the credentials from a previous successful authentication. This could be exploited to read diagnostic information and attain limited remote code execution. (CVE-2013-4112) A flaw was discovered in the way authenticated connections were cached on the server by remote-naming. After a user has successfully logged in, a remote attacker could use a remoting client to log in as that user without knowing their password, allowing them to access data and perform actions with the privileges of that user. (CVE-2013-4128) A flaw was discovered in the way connections for remote EJB invocations via the EJB client API were cached on the server. After a user has successfully logged in, a remote attacker could use an EJB client to log in as that user without knowing their password. (CVE-2013-4213) 3. Solution: Red Hat would like to thank Tibor Jager, Kenneth G. Paterson and Juraj Somorovsky of Ruhr-University Bochum for reporting CVE-2012-5575; and Andreas Falkenberg of SEC Consult Deutschland GmbH, and Christian Mainka, Juraj Somorovsky, and Joerg Schwenk of Ruhr-University Bochum for reporting CVE-2013-2160. CVE-2012-4572 was discovered by Josef Cacek of the Red Hat JBoss EAP Quality Engineering team; CVE-2013-4128 and CVE-2013-4213 were discovered by Wolf-Dieter Fink of the Red Hat GSS Team; and CVE-2013-2102 was discovered by Red Hat. All users of Red Hat JBoss Portal 6.0.0 as provided from the Red Hat Customer Portal are advised to upgrade to Red Hat JBoss Portal 6.1.0. The References section of this erratum contains a download link (you must log in to download the update). Before applying the update, back up all applications deployed on JBoss Enterprise Portal Platform, along with all customized configuration files, and any databases and database settings. 4.
