"The version of Apache Struts running on the remote host is 2.3.5
through 2.3.31 or else 2.5.x prior to 2.5.10.1. It is, therefore,
affected by a remote code execution vulnerability in the Jakarta
Multipart parser due to improper handling of the Content-Type,
Content-Disposition, and Content-Length headers. An unauthenticated,
remote attacker can exploit this, via a specially crafted header value
in the HTTP request, to potentially execute arbitrary code.

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