Synopsis

Apache Struts 2.x < 2.5.29 Remote Code Execution (S2-062)

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.

Solution

Refer to the S2-062 vendor advisory for mitigation options.
