Vulnerability Information

Severity: High
Vulnerability Published: 2014-04-29
Patch Published: N/A
CVE [?]: CVE-2014-0114
CPE [?]: cpe:/a:apache:struts

Synopsis

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

Description

The remote web application appears to use Struts, a web application framework. The version of Struts in use contains a flaw that allows the manipulation of the ClassLoader via the 'class' parameter of an ActionForm object that results a denial of service.

Note that this vulnerability may be exploited to execute arbitrary remote code in certain application servers with specific configurations; however, Nessus has not tested for this issue.

Additionally, note that this plugin will only report the first vulnerable instance of a Struts application.

Solution

Unknown at this time. Note that Struts 1 has reached end-of-life and is no longer supported.

How to Run

Here is how to run the Apache Struts ClassLoader Manipulation as a standalone plugin via the Nessus web user interface (https://localhost:8834/):

Click to start a New Scan.
Select Advanced Scan.
Navigate to the Plugins tab.
On the top right corner click to Disable All plugins.
On the left side table select Denial of Service plugin family.
On the right side table select Apache Struts ClassLoader Manipulation plugin ID 73919.
Specify the target on the Settings tab and click to Save the scan.
Run the scan.

Here are a few examples of how to run the plugin in the command line. Note that the examples below demonstrate the usage on the Linux / Unix platform.

Basic usage:

/opt/nessus/bin/nasl struts_classloader_manipulation.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a struts_classloader_manipulation.nasl -t <IP/HOST>

Run the plugin with trace script execution written to the console (useful for debugging):

/opt/nessus/bin/nasl -T - struts_classloader_manipulation.nasl -t <IP/HOST>

Run the plugin with using a state file for the target and updating it (useful for running multiple plugins on the target):

/opt/nessus/bin/nasl -K /tmp/state struts_classloader_manipulation.nasl -t <IP/HOST>

Go back to menu.
