  - 'syslog.dump' and 'configfile.dump' files accessible without authentication.

  - Credentials and other sensitive information are stored in plain text.

  - The usage of defaults credentials like 'admin:admin', 'viewer:viewer', 'rviewer:rviewer'.

  - An improper input validation for parameter 'action' to the 'NotificationTest.cgi' script leading
  to a cross-site scripting (XSS) vulnerability

  - A cross-site request forgery (CSRF) vulnerability.");
