"According to its version number, the Splunk Enterprise hosted on the
remote web server is 6.1.x prior to 6.1.3. It is, therefore, affected
by the following vulnerabilities :

  - A path traversal vulnerability exists due to a flaw
    related to search IDs, in which user input is not
    properly sanitized. A remote, authenticated attacker can
    exploit this, via a specially crafted URL, to read
    arbitrary files outside the restricted path.
    (CVE-2014-5197)

  - A cross-site scripting vulnerability exists due to the
    referrer header not being properly validated before
    returning it to users. A remote attacker can exploit
    this, via a specially crafted request, to execute script
    code in a user's browser session. (CVE-2014-5198)

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