CVE-2021-31805 Information

Description

The fix issued for CVE-2020-17530 was incomplete. So from Apache Struts 2.0.0 to 2.5.29 still 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.
