Use of Weak Credentials

The product uses weak credentials (such as a default key or hard-coded password) that can be calculated, derived, reused, or guessed by an attacker.

31 linked vulnerabilities

Extended Description

Hard-coded (i.e., static and unchangeable by the administrator)
Default (i.e., the same static value across different deployments/installations, but able to be changed by the administrator)
Predictable (i.e., generated in a way that produces unique credentials across deployments/installations, but can still be guessed with reasonable efficiency)
Previously Compromised (i.e., "leaked" credentials that were published as part of a data breach)

Architecture and DesignOperation

When the user changes or sets a password, check the password against a database of already compromised or breached passwords. These passwords are likely to be used in password guessing attacks.

Access ControlBypass Protection Mechanism

An adversary could bypass intended authentication restrictions.
