  - Two Remote Command Injection vulnerabilities in its web administrative interface. These vulnerabilities occur
  in the diagnostics CGI (/cgi-bin/diagnostics) component responsible for emailing out information about the state
  of the system. (CVE-2016-9682)

  - Remote Command Injection vulnerability in its web administrative interface. This vulnerability occurs in the
  'extensionsettings' CGI (/cgi-bin/extensionsettings) component responsible for handling some of the server's
  internal configurations. (CVE-2016-9683)

  - Remote Command Injection vulnerability in its web administrative interface. This vulnerability occurs in the
  'viewcert' CGI (/cgi-bin/viewcert) component responsible for processing SSL certificate information.
