The underlying weakness: Use of Default Password

The product uses default passwords for potentially critical functionality.

How developers prevent this class of flaw

  • Prohibit use of default, hard-coded, or other values that do not vary for each installation of the product - especially for separate organizations.
  • Ensure that product documentation clearly emphasizes the presence of default passwords and provides steps for the administrator to change them.
  • Force the administrator to change the credential upon installation.
