Apache Struts 2.0.0 < 2.5.30 Possible Remote Code Execution vulnerability (S2-062)

critical Nessus Plugin ID 159667

Language:

Synopsis

Apache Struts installed on the remote host is affected by Possible Remote Code Execution vulnerability

Description

The version of Apache Struts installed on the remote host is prior to 2.5.30. It is, therefore, affected by a vulnerability as referenced in the S2-062 advisory.

- The fix issued for CVE-2020-17530 ( S2-061 ) was incomplete. 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. (CVE-2021-31805)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Apache Struts version 2.5.30 or later. Alternatively, apply the workaround as referenced in in the vendor's security bulletin
