How to fix?

Upgrade opensymphony:xwork to version 2.0.4 or higher.

Overview

opensymphony:xwork is a generic command pattern framework. It forms the core of Struts 2.

Affected versions of this package are vulnerable to Arbitrary OGNL Statemant Execution. It recursively evaluates all input as an Object-Graph Navigation Language (OGNL) expression when altSyntax is enabled, which allows remote attackers to cause a denial of service (infinite loop) or execute arbitrary code via form input beginning with a %{ sequence and ending with a } character.
