CVE: CVE-2019-0230
Apache Struts is an open-source web application framework for developing Java EE web applications. It uses and extends the Java Servlet API to encourage developers to adopt a model-view-controller (MVC) architecture.
Struts uses Object-Graph Navigation Language (OGNL) to provide extensive expression evaluation capabilities.
Apache Struts can be forced to use double OGNL evaluation, which could allow a remote attacker to execute arbitrary code by sending a specially crafted request.
Upgrade to Struts 2.5.22 or higher.
