Synopsis

The remote web server contains an application that is affected by multiple vulnerabilities.

Description

According to its version number, the Splunk Enterprise hosted on the remote web server is 6.0.x prior to 6.0.7. It is, therefore, affected by the following vulnerabilities :

- A man-in-the-middle (MitM) information disclosure vulnerability, known as POODLE, exists due to the way SSL 3.0 handles padding bytes when decrypting messages encrypted using block ciphers in cipher block chaining (CBC) mode. A MitM attacker can decrypt a selected byte of a cipher text in as few as 256 tries if they are able to force a victim application to repeatedly send the same data over newly created SSL 3.0 connections. (CVE-2014-3566)

- A flaw exists in the included OpenSSL library due to handling session tickets that have not been properly verified for integrity. A remote attacker, by using a large number of invalid session tickets, can exploit this to cause a denial of service. (CVE-2014-3567)

- A cross-site scripting flaw exists within the Dashboard due to improperly validating input. This allows a remote attacker, using a specially crafted request, to execute arbitrary script code in the user's browser session within the trust relationship. (CVE-2014-5466)

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 Splunk Enterprise 6.0.7 or later.

How to Run

Here is how to run the Splunk Enterprise 6.0.x < 6.0.7 Multiple Vulnerabilities (POODLE) 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 CGI abuses plugin family.
On the right side table select Splunk Enterprise 6.0.x < 6.0.7 Multiple Vulnerabilities (POODLE) plugin ID 79723.
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 splunk_607.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a splunk_607.nasl -t <IP/HOST>

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

/opt/nessus/bin/nasl -T - splunk_607.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 splunk_607.nasl -t <IP/HOST>

Go back to menu.
