"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.");
