The remote host contains a web application that uses a Java framework that is affected by a remote code execution vulnerability.
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 18.104.22.168. 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.
Upgrade to Apache Struts version 2.3.32 / 22.214.171.124 or later. Alternatively, apply the workaround referenced in the vendor advisory.
