CWE-1391Use of Weak Credentials

Abstraction: Class · CVEs in our corpus: 51

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.

By design, authentication protocols try to ensure that attackers must perform brute force attacks if they do not know the credentials such as a key or password. However, when these credentials are easily predictable or even fixed (as with default or hard-coded passwords and keys), then the attacker can defeat the mechanism without relying on brute force. Credentials may be weak for different reasons, such as: Even if a new, unique credential is intended to be generated for each product installation, if the generation is predictable, then that may also simplify guessing attacks.

This weakness contributes to A07:2025 Authentication Failures.

NIST 800-53 r5 controls that address this weakness (2)AI

Control Title Family Why it addresses this CWE
IA-5Authenticator ManagementIAEnsuring sufficient strength of mechanism for authenticators prevents use of weak credentials.
IA-7Cryptographic Module AuthenticationIAEnforces use of credentials that comply with standards rather than weak credentials for module access.

MITRE ATT&CK techniques this weakness enables

Our own two-way CWE↔ATT&CK cross-walk — a direct mapping with no public source (the CWE→CAPEC→ATT&CK chain leaves most top weaknesses, incl. XSS and SQLi, mapped to nothing). Drafted by Grok and spot-checked by Claude Opus 4.8.

Direction: other covers this; this covers other (F/M/P = full / mostly / partial).
