According to its version number, the Splunk Enterprise hosted on the remote web server is version 6.2.x prior to 6.2.2. It is, therefore, affected by the following vulnerabilities :
A flaw exists with ECDH handshakes when using an ECDSA certificate without a ServerKeyExchange message. This allows a remote attacker to trigger a loss of forward secrecy from the ciphersuite. (CVE-2014-3572)
A security feature bypass vulnerability, known as FREAK (Factoring attack on RSA-EXPORT Keys), exists due to the support of weak EXPORT_RSA cipher suites with keys less than or equal to 512 bits. A man-in-the-middle attacker may be able to downgrade the SSL/TLS connection to use EXPORT_RSA cipher suites which can be factored in a short amount of time, allowing the attacker to intercept and decrypt the traffic. (CVE-2015-0204)
A denial of service vulnerability exists in Splunk Web that allows a remote attacker, using a specially crafted request, to trigger an assert and thus crash the Splunk Enterprise instance. (SPL-93754)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
