Description

JBoss Enterprise Application Platform 6 is a platform for Java applications based on JBoss Application Server 7.

This release serves as a replacement for JBoss Enterprise Application Platform 6.0.0, and includes bug fixes and enhancements. Refer to the 6.0.1 Release Notes for information on the most significant of these changes, available shortly from https://access.redhat.com/knowledge/docs/

Security fixes:

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. (CVE-2012-2379)

When using role-based authorization to configure EJB access, JACC permissions should be used to determine access; however, due to a flaw the configured authorization modules (JACC, XACML, etc.) were not called, and the JACC permissions were not used to determine access to an EJB. (CVE-2012-4550)

A flaw in the way Apache CXF enforced child policies of WS-SecurityPolicy 1.1 on the client side could, in certain cases, lead to a client failing to sign or encrypt certain elements as directed by the security policy, leading to information disclosure and insecure information transmission. (CVE-2012-2378)

A flaw was found in the way IronJacamar authenticated credentials and returned a valid datasource connection when configured to "allow-multiple-users". A remote attacker, provided the correct subject, could obtain a datasource connection that might belong to a privileged user. (CVE-2012-3428)

It was found that Apache CXF was vulnerable to SOAPAction spoofing attacks under certain conditions. Note that WS-Policy validation is performed against the operation being invoked, and an attack must pass validation to be successful. (CVE-2012-3451)

When there are no allowed roles for an EJB method invocation, the invocation should be denied for all users. It was found that the processInvocation() method in org.jboss.as.ejb3.security.AuthorizationInterceptor incorrectly authorizes all method invocations to proceed when the list of allowed roles is empty. (CVE-2012-4549)

The apachectl script set an insecure library search path. Running apachectl in an attacker-controlled directory containing a malicious library file could cause arbitrary code execution with the privileges of the user running the apachectl script (typically the root user). This issue only affected JBoss Enterprise Application Platform on Solaris. (CVE-2012-0883)

It was found that in Mojarra, the FacesContext that is made available during application startup is held in a ThreadLocal. The reference is not properly cleaned up in all cases. As a result, if a JavaServer Faces (JSF) WAR calls FacesContext.getCurrentInstance() during application startup, another WAR can get access to the leftover context and thus get access to the other WAR's resources. A local attacker could use this flaw to access another WAR's resources using a crafted, deployed application. (CVE-2012-2672)

An input sanitization flaw was found in the mod_negotiation Apache HTTP Server module. A remote attacker able to upload or create files with arbitrary names in a directory that has the MultiViews options enabled, could use this flaw to conduct cross-site scripting attacks against users visiting the site. (CVE-2008-0455, CVE-2012-2687)

Red Hat would like to thank the Apache CXF project for reporting CVE-2012-2379, CVE-2012-2378, and CVE-2012-3451. The CVE-2012-4550 issue was discovered by Josef Cacek of the Red Hat JBoss EAP Quality Engineering team; CVE-2012-3428 and CVE-2012-4549 were discovered by Arun Neelicattu of the Red Hat Security Response Team; and CVE-2012-2672 was discovered by Marek Schmidt and Stan Silvert of Red Hat.
