Splunk 6.x < 6.0.3 Multiple OpenSSL Vulnerabilities (Heartbleed)

medium Nessus Plugin ID 73575
New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it is different from CVSS.

VPR Score: 7.3


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


According to its version number, the Splunk Web hosted on the remote web server is 6.x prior to 6.0.3. It is, therefore, affected by multiple OpenSSL-related vulnerabilities :

- A flaw exists with the OpenSSL version being used by Splunk with the 'ssl3_take_mac' in 'ssl/s3_both.c'. This allows a remote attacker to cause a denial of service with a specially crafted request. (CVE-2013-4353)

- An out-of-bounds read error, known as Heartbleed, exists in the TLS/DTLS implementation due to improper handling of TLS heartbeat extension packets. A remote attacker, using crafted packets, can trigger a buffer over-read, resulting in the disclosure of up to 64KB of process memory, which contains sensitive information such as primary key material, secondary key material, and other protected content. (CVE-2014-0160)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.


Upgrade to Splunk 6.0.3 or later.
