Cumulative inbound coverage
How completely the frameworks we cross-walk collectively cover this — the verdict is the strongest single mapping (overlapping partials are not summed); breadth shows the corroboration behind it.
Collective: full · 6 mapping(s) from 5 framework(s): ASVS 5.0 2 (full) · OWASP-Web 1 (full) · STIG oracle linux 8 1 (mostly) · STIG rhel 8 1 (mostly) · ATT&CK 1 (partial)

This weakness contributes to A04:2025 Cryptographic Failures.
NIST 800-53 r5 controls that address this weakness (1)AI
| Control | Title | Family | Why it addresses this CWE |
|---|---|---|---|
SC-12 | Cryptographic Key Establishment and Management | SC | Managed key generation relies on PRNGs seeded and operated with adequate entropy, avoiding the listed weakness. |
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).
