CWE-1393: Use of Default Password
CWE版本: 4.18
更新日期: 2025-09-09
弱点描述
The product uses default passwords for potentially critical functionality.
扩展描述
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.
常见后果
