CVE [?]: CVE-2017-12617
CPE [?]: cpe:/a:apache:tomcat

Synopsis

The remote Apache Tomcat server is affected by a code execution vulnerability.

Description

The version of Apache Tomcat installed on the remote host is 7.0.x prior to 7.0.82 or 8.5.x prior to 8.5.23. It is, therefore, affected by an unspecified vulnerability when running with HTTP PUTs enabled (e.g. via setting the readonly initialization parameter of the Default to false) that makes it possible to upload a JSP file to the server via a specially crafted request. This JSP could then be requested and any code it contained would be executed by the server.

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

Solution

Upgrade to Apache Tomcat version 7.0.82 / 8.5.23 or later.

How to Run

---

Here is how to run the Apache Tomcat 7.0.x < 7.0.82 / 8.5.x < 8.5.23 Multiple Vulnerabilities as a standalone plugin via the Nessus web user interface (https://localhost:8834/):

1. Click to start a New Scan.
2. Select Advanced Scan.
3. Navigate to the Plugins tab.
4. On the top right corner click to Disable All plugins.
5. On the left side table select Web Servers plugin family.
6. On the right side table select Apache Tomcat 7.0.x < 7.0.82 / 8.5.x < 8.5.23 Multiple Vulnerabilities plugin ID 103698.
7. Specify the target on the Settings tab and click to Save the scan.
8. 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 tomcat_8_5_23.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a tomcat_8_5_23.nasl -t <IP/HOST>

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

/opt/nessus/bin/nasl -T - tomcat_8_5_23.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 tomcat_8_5_23.nasl -t <IP/HOST>

Go back to menu.
