MITRE ATT&CK Enterprise TechniquesAI

T1069 Permission Groups Discovery Discovery
Adversaries may attempt to discover group and permission settings.
T1078 Valid Accounts Stealth
Adversaries may obtain and abuse credentials of existing accounts as a means of gaining Initial Access, Persistence, Privilege Escalation, or Defense Evasion.
Why these techniques?

Missing authorization (CWE-862) in a WordPress plugin allows an attacker to access functionality that should be restricted, which can facilitate permission groups discovery (T1069) and use of valid accounts (T1078) to abuse improperly constrained ACLs.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly enforces authorization policy checks before allowing access to plugin functionality, preventing the unauthorized actions described by CWE-862.

prevent

Limits privileges granted to any user or session, reducing the impact of missing ACL enforcement on coupon-affiliate functions.

prevent

Enforces information-flow rules that can block unauthorized data or function access paths exploited by the missing-authorization flaw.

PR.AA-05 full match
prevents

Explicitly requires defining, enforcing, and reviewing authorizations and least privilege, directly preventing missing authorization checks.

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.

prevents

Requiring authentication and credentials before any access occurs eliminates the absence of authorization checks that would otherwise allow an unauthenticated actor to reach protected resources.

prevents

Requiring formal authorization of every access request before rights are granted ensures that checks for required permissions are performed, preventing missing authorization checks from being introduced.

prevents

Mandatory authorization checks and central records of granted rights ensure that every access attempt is preceded by an explicit decision rather than relying on missing checks.

mitigates

Segregating the approval of access rights from their implementation provides an independent check that reduces the impact of missing authorization checks in the resulting system configuration.

detects

By requiring competent outsiders to verify that every function enforces the need-to-know principle, the control lowers the likelihood that missing authorization checks persist undetected.

prevents

Defining authorization responsibilities and reviewing risk-treatment progress throughout the project lifecycle catches missing authorization checks before the system is deployed.
