Mitigating Controls

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.

addresses: CWE-863

Periodic review and update of procedures reduces incorrect authorization implementations over time.

addresses: CWE-863

Supervision identifies cases where authorization logic incorrectly permits unauthorized actions.

addresses: CWE-863

Defining permitted attribute values and auditing modifications reduces the chance of incorrect authorization outcomes due to tampered or missing labels.

addresses: CWE-863

The authorization process and usage restrictions help prevent incorrect authorization for remote access types.

addresses: CWE-863

Establishing configuration and connection requirements helps ensure correct rather than incorrect authorization for wireless access.

addresses: CWE-863

Establishing connection authorization processes for mobile devices helps ensure authorization decisions are correctly implemented rather than incorrect.

addresses: CWE-863

Monitoring account use, notifying on changes, and reviewing accounts for compliance corrects incorrect authorization assignments.

addresses: CWE-863

Ensures authorization decisions for external system use are correctly implemented and enforced.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

blocks

A.5.10 only requires awareness, a topic-specific acceptable-use policy stating expected behaviours/monitoring, and procedures referencing other controls (e.g. access restrictions, marking, disposal); it performs none of the verb on CWE-522's insecure credential transmission/storage, which requires technical protections like encryption or secure channels that this governance clause does not supply.

blocks

Requiring consistency between access rights and classification plus formal approval steps ensures that the authorization logic correctly distinguishes between entities that should and should not be granted access.

blocks

A.5.17 mandates secure allocation, transmission, storage, hashing/encryption per 8.24, strong non-reusable passwords, immediate change of defaults/compromise, and no cleartext — directly stopping exploitation of insufficiently protected credentials with only a bounded remainder (e.g. non-password authenticators or post-storage exposure vectors outside its scope).

blocks

A.5.18's provisioning, revocation, review and adjustment of access rights (incl. before role changes/termination, with segregation and owner approval) directly stops incorrect authorization decisions from being exploitable in the vast majority of cases; the bounded remainder is incorrectness inside the authorization logic itself (e.g. flawed conditional or missing check) rather than rights that were wrongly granted.

blocks

A.6.2 sets contractual terms, NDAs, and communicates responsibilities to personnel; it has no technical effect on how credentials are protected in transmission or storage and cannot stop exploitation of CWE-522

blocks

Regular reminders about password security and personal accountability make users less likely to store or transmit credentials in cleartext or other unprotected forms.

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.

  • No fine-grained STIG row for CWE-522, a class-level weakness. Rules are authored against its narrower children: CWE-260, CWE-523.
  • No fine-grained STIG row for CWE-863, a class-level weakness, and none of its children carries one either.
