Is Crowd vulnerable to CVE-2018-11776 (Apache Struts)

[Thomas Douglas]

Hello, I was wondering if Crowd is vulnerable to this report CVE-2018-11776? I am using Crowd 2.11.1.

Apache Struts implementation are vulnerable to the reported RCE flaw if it meets the following conditions:

·         The alwaysSelectFullNamespace flag is set to true in the Struts configuration.

·         Struts configuration file contains an "action" or "url" tag that does not specify the optional namespace attribute or specifies a wildcard namespace.
