Apache Struts 2.x < 2.3.24.1 Request Parameter 'top' Object Access Handling Remote Manipulation

This script is Copyright (C) 2016 Tenable Network Security, Inc.


Synopsis :

The remote Windows host contains a web application that uses a Java
framework that is affected by a remote manipulation vulnerability.

Description :

The version of Apache Struts installed on the remote Windows host is
version 2.x prior to 2.3.24.1. It is, therefore, affected by a remote
manipulation vulnerability due to incorrect handling of the 'top'
object. An unauthenticated, remote attacker can exploit this, via a
specially crafted request, to manipulate internal components
and container settings.

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

Solution :

Upgrade to Apache Struts version 2.3.24.1 or later. Alternatively,
apply the workaround referenced in the vendor advisory.
