How to fix?

Upgrade org.apache.struts:struts2-core to version 2.2.1 or higher.

Overview

org.apache.struts:struts2-core is a popular open-source framework for developing web applications in the Java programming language.

Affected versions of this package are vulnerable to Arbitrary OGNL Statement Execution. ParametersInterceptor as used in Apache Struts and other products, does not properly restrict # (pound sign) references to context objects, which allows remote attackers to execute Object-Graph Navigation Language (OGNL) statements and modify server-side context objects, as demonstrated by use of a \u0023 representation for the # character.
