Severity ?
CWE
  • CWE-917 - Improper Neutralization of Special Elements used in an Expression Language Statement ('Expression Language Injection')
Summary
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.
