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."
