Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

CM-6 Configuration Settings
addresses: CWE-521

Configuration settings can define and enforce strong password requirements to avoid weak policies.

IA-1 Policy and Procedures
addresses: CWE-521

IA policy establishes password requirements, directly addressing weak password requirements.

IA-5 Authenticator Management
addresses: CWE-521

Ensuring authenticators have sufficient strength of mechanism for intended use addresses weak password requirements.

PL-9 Central Management
addresses: CWE-521

Organization-wide password and authentication policies are applied uniformly, preventing weak local password requirements.

PM-15 Security and Privacy Groups and Associations
addresses: CWE-521

Facilitated training and awareness of current practices improves definition and enforcement of sufficiently strong password requirements.

PM-3 Information Security and Privacy Resources
addresses: CWE-521

Dedicated security resources support deployment of strong authentication systems and enforcement of robust password policies.

RA-5 Vulnerability Monitoring and Scanning
addresses: CWE-521

Vulnerability scans assess password policies and weak credential requirements against benchmarks.

SA-5 System Documentation
addresses: CWE-521

User documentation on maintaining security includes password requirements, directly mitigating weak password policies.

A.5.17 Authentication information mostly match
prevents

Enforcing minimum length, complexity, non-dictionary, and non-reuse rules directly counters weak password policies that allow attackers to guess or brute-force credentials.

Hardening callouts derived

Configuration rules from DISA STIG baselines that bear on weaknesses of the type cited by this CVE. Each rule is shown with the relationship its mapping actually records, against the CWE it was authored against. Derived via CVE→CWE over `controls_xwalks` (authoritative rows only; rows rated `none` are excluded).

RHEL 7 (2 rules)
  • V-204424 The Red Hat Enterprise Linux operating system must not allow accounts configured with blank or null passwords. prevents CWE-521
  • V-204425 The Red Hat Enterprise Linux operating system must be configured so that the SSH daemon does not allow authentication using an empty password. prevents CWE-521
