[org.apache.struts:struts2-core] Path Traversal in Apache Struts

In Apache Struts 2.3.x before 2.3.31, and 2.5.x before 2.5.5, it is possible to prepare a special URL which will be used for path traversal and execution of arbitrary code on server side. This vulnerability is only exploitable when using the Struts 2 Convention plugin in conjunction with Apache Struts.
