The version of Apache Struts running on the remote host is 2.3.x prior to 2.3.35, or 2.5.x prior to 2.5.17. It, therefore, contains a possible remote code execution vulnerability when results are used without setting a namespace along with an upper action that does not have a namespace set or has a wildcard namespace set.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
