"A web application running on the remote host uses a Java framework
that is affected by a possible remote code execution.");
  script_set_attribute(attribute:"description", value:
"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.");
