Description

Apache Struts is a framework for building web applications with Java.

It was found that the Struts 1 ActionForm object allowed access to the
'class' parameter, which is directly mapped to the getClass() method. A
remote attacker could use this flaw to manipulate the ClassLoader used by
an application server running Struts 1. This could lead to remote code
execution under certain conditions. (CVE-2014-0114)

All struts users are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue. All running applications
using struts must be restarted for this update to take effect.
