CWE-1393: Use of Default Password
The product uses default passwords for potentially critical functionality.
How it's found
Use of Default Password is typically found by tracing untrusted input from where it enters the system to the point where it is used without the check or neutralization this weakness describes, combining manual code review with dynamic testing.
It is common practice for products to be designed to use default passwords for authentication. The rationale is to simplify the manufacturing process or the system administrator's task of installation and deployment into an enterprise. However, if admins do not change the defaults, then it makes it easier for attackers to quickly bypass authentication across multiple organizations. There are many lists of default passwords and default-password scanning tools that are easily available from the World Wide Web.
Consequences
- Gain Privileges or Assume Identity
Mitigations
- Requirements: Prohibit use of default, hard-coded, or other values that do not vary for each installation of the product - especially for separate organizations.
- Documentation: Ensure that product documentation clearly emphasizes the presence of default passwords and provides steps for the administrator to change them.
- Architecture and Design: Force the administrator to change the credential upon installation.
- Installation/Operation: The product administrator could change the defaults upon installation or during operation.
