					This module exploits a remote command execution vulnerability in
				Apache Struts versions < 2.2.1.1. This issue is caused because the
				ExceptionDelegator interprets parameter values as OGNL expressions
				during certain exception handling for mismatched data types of properties,
				which allows remote attackers to execute arbitrary Java code via a
				crafted parameter.
