According to its version number, the Splunk Web hosted on the remote web server is affected by multiple code execution vulnerabilities :
A directory traversal vulnerability exists in the collect script. A remote attacker can exploit this, using the ‘file’ parameter, to execute arbitrary commands. (CVE-2013-6771)
A flaw exists in the ‘echo.sh’ script that allows a remote, authenticated attacker to execute arbitrary commands on the underlying operating system by using a specially crafted string. (CVE-2013-7394)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
