  - No CVE: The vulnerability exists in a section of the machine's administrative interface for
  performing configurations related to on-connect scripts to be launched for users's connecting.

  - CVE-2016-9682: 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-2016-9683: 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-2016-9684: 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.");
