Description David Jorm 2012-06-07 03:12:55 UTC

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 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.

Upstream bug: http://java.net/jira/browse/JAVASERVERFACES-2436

Created jboss-jsf-2.1-api tracking bugs for this issue

Affects: fedora-17 [bug 830024]

Comment 6 David Jorm 2012-07-12 01:16:20 UTC

This issue has been resolved upstream in Mojarra 2.1.11 and 2.2-m05. A patch and updated JARs are attached to the upstream bug: http://java.net/jira/browse/JAVASERVERFACES-2436

Comment 8 David Jorm 2012-08-06 04:32:32 UTC

The upstream Mojarra fix for this issue introduced a class loader leak. An updated patch that resolves both the security issue and the class loader leak will be available in Mojarra 2.1.12.
