CPE [?]: cpe:/a:splunk:splunk

Synopsis

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

Description

According to its version number, the Splunk Enterprise hosted on the remote web server is 4.3.x, 5.0.x prior to 5.0.9, 6.0.x prior to 6.0.5, or 6.1.x prior to 6.1.2. It is, therefore, affected by multiple OpenSSL-related vulnerabilities :

- An unspecified error exists that allows an attacker to cause usage of weak keying material, resulting in simplified man-in-the-middle attacks. (CVE-2014-0224)

- An unspecified error exists related to anonymous ECDH cipher suites that allow denial of service attacks. Note that this issue only affects OpenSSL TLS clients. (CVE-2014-3470)

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 5.0.9 / 6.0.5 / 6.1.2 or later as appropriate.

How to Run

Here is how to run the Splunk Enterprise 4.3.x / 5.0.x < 5.0.9 / 6.0.x < 6.0.5 / 6.1.x < 6.1.2 Multiple OpenSSL Vulnerabilities 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 Web Servers plugin family.
On the right side table select Splunk Enterprise 4.3.x / 5.0.x < 5.0.9 / 6.0.x < 6.0.5 / 6.1.x < 6.1.2 Multiple OpenSSL Vulnerabilities plugin ID 76528.
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_605.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a splunk_605.nasl -t <IP/HOST>

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

/opt/nessus/bin/nasl -T - splunk_605.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_605.nasl -t <IP/HOST>

Go back to menu.
