CVE-2023-37464

Contacts with security groups provide timely information on broken or risky cryptographic algorithms, reducing the likelihood of their selection and use.

Ongoing education and sharing of recommended practices helps organizations identify and migrate away from broken or risky cryptographic algorithms.

Cross-organization threat feeds commonly include advances in cryptanalysis and active exploits against weak or broken algorithms, allowing organizations to deprecate them proactively.

Capital planning and funding allow selection and ongoing support of strong cryptographic algorithms rather than weak or broken ones.

Risk updates surface newly-broken or risky cryptographic algorithms as threat intelligence and computing advances evolve, enabling timely replacement.

Scanners flag use of broken or weak cryptographic algorithms via known-vulnerability databases.

Enforces approved cryptographic algorithms for each use case, blocking use of broken or risky algorithms.

Flaw remediation replaces broken or risky cryptographic algorithms once safer implementations are released by vendors.

A.5.31 only requires identifying, reviewing and considering legal/regulatory/contractual requirements (including crypto restrictions); it does not itself stop use of a broken algorithm or block its exploitation

A.5.6 only promotes membership in groups to receive early warnings, advisories, and specialist advice about vulnerabilities (including risky crypto); it does not stop exploitation of an already-present broken algorithm, which requires other controls (e.g. A.8.24) to act.

A.8.24's policy, algorithm selection, strength/quality rules, approved standards and key management directly stop use of broken/risky algorithms in most cases; the bounded remainder is non-compliant implementations or legacy systems grandfathered under the clause's own regulatory and transition guidance.
