High Nessus Plugin ID 117457
Synopsis
A web application running on the remote host uses a Java framework that is affected by multiple ClassLoader manipulation vulnerabilities.
Description
The version of Apache Struts running on the remote host is 2.x prior to 2.3.16.2. It, therefore, is affected by multiple ClassLoader vulnerabilities.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Upgrade to Apache Struts version 2.3.16.2 or later
