XML External Entity (XXE)

Red Hat JBoss Enterprise Application Platform 6 is a platform for Java applications based on JBoss Application Server 7. Apache CXF is an open source services framework, which is a part of Red Hat JBoss Enterprise Application Platform. It was found that the SecurityTokenService (STS), provided as a part of Apache CXF, could under certain circumstances accept invalid SAML tokens as valid. A remote attacker could use a specially crafted SAML token to gain access to an application that uses STS for validation of SAML tokens. (CVE-2014-0034) A denial of service flaw was found in the way Apache CXF created error messages for certain POST requests. A remote attacker could send a specially crafted request which, when processed by an application using Apache CXF, could consume an excessive amount of memory on the system, possibly triggering an Out Of Memory (OOM) error. (CVE-2014-0109) It was found that when a large invalid SOAP message was processed by Apache CXF, it could be saved to a temporary file in the /tmp directory. A remote attacker could send a specially crafted SOAP message that, when processed by an application using Apache CXF, would use an excessive amount of disk space, possibly causing a denial of service. (CVE-2014-0110) It was found that the Java API for RESTful Web Services (JAX-RS) implementation enabled external entity expansion by default. A remote attacker could use this flaw to view the contents of arbitrary files accessible to the application server user. (CVE-2014-3481) It was discovered that UsernameTokens were sent in plain text by an Apache CXF client that used a Symmetric EncryptBeforeSigning password policy. A man-in-the-middle attacker could use this flaw to obtain the user name and password used by the client application using Apache CXF. (CVE-2014-0035) The CVE-2014-3481 issue was discovered by the Red Hat JBoss Enterprise Application Platform QE team. This release serves as a replacement for Red Hat JBoss Enterprise Application Platform 6.2.3, and includes bug fixes and enhancements. Documentation for these changes will be available shortly from the Red Hat JBoss Enterprise Application Platform 6.2.4 Release Notes, linked to in the References. All users of Red Hat JBoss Enterprise Application Platform 6.2 on Red Hat Enterprise Linux 5 are advised to upgrade to these updated packages. The JBoss server process must be restarted for the update to take effect.
