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.
Detects unauthorized successful logons resulting from improper authentication implementations.
Documented procedures ensure personnel are trained on authentication mechanisms, tangibly lowering the risk of improper authentication being exploited.
Security awareness training instructs users on secure authentication practices and avoiding credential compromise.
Training on authentication mechanisms and best practices decreases the occurrence of improper authentication.
Contacts with security groups provide timely information on broken or risky cryptographic algorithms, reducing the likelihood of their selection and use.
Non-repudiation requires strong authentication mechanisms to irrefutably attribute performed actions to specific individuals or processes.
Session content review can reveal authentication bypasses or failures in session establishment.
Review of authentication-related audit records can detect improper authentication mechanisms or bypasses.

A.5.17's password management system requirements (h: store/transmit in protected form; approved crypto per 8.24; no recoverable formats implied by strong practices) stop exploitation of recoverable storage for most cases, but the remainder (non-password auth info or systems outside the password management system) is nameable.
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.
Requires proper use of cryptography, which can mitigate recoverable storage if applied correctly to passwords.
Hardening callouts derived
DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.
