Vulnerability Information

Severity: Medium
Vulnerability Published: 2014-08-06
Patch Published: 2014-09-30
CVE [?]: CVE-2014-3511, CVE-2014-8303
CPE [?]: cpe:/a:splunk:splunk

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 6.0.6. It is, therefore, affected by the following vulnerabilities :

- The included OpenSSL library contains a TLS downgrade weakness. By using fragmented ClientHello messages, a remote, man-in-the-middle attacker can force a downgrade to TLS 1.0. (CVE-2014-3511)

- A cross-site scripting vulnerability exists due to improper validation of user-supplied input when parsing events. 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-2014-8303)

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 6.0.6 or later.

Public Exploits
