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 Remote Code Execution (RCE). The fix issued for CVE-2020-17530 was incomplete. Some of the tag’s attributes could perform a double evaluation if a developer applied forced OGNL evaluation by using the %{...} syntax. Using forced OGNL evaluation on untrusted user input can lead to a Remote Code Execution and security degradation.
