Upgrade org.apache.struts:struts2-core to version 2.5.22 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 Denial of Service (DoS). When a file upload is performed to an Action that exposes the file with a getter, an attacker may manipulate the request such that the working copy of the uploaded file is set to read-only. As a result, subsequent actions on the file will fail with an error. It might also be possible to set the Servlet container's temp directory to read-only, such that subsequent upload actions will fail.
