Threat & Defense at a Glance
Threat & Defense Details
Likely Mitigating ControlsAI
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.
Documented procedures facilitate correct implementation and ongoing management of authorization decisions.
Periodic reviews identify and correct flaws in authorization decisions or enforcement.
Specifying access authorizations for each account and requiring approvals for account requests enforces proper authorization decisions.
The control requires explicit definition of separated access authorizations, making incorrect privilege assignments that bundle conflicting duties harder to implement.
Ensures privileges are assigned only as necessary rather than incorrectly over-granted.
The control's documentation requirement reduces improper authorization by ensuring only mission-justified actions bypass authentication.
Establishing permitted attributes and values, plus auditing changes, ensures authorization decisions are based on correctly managed policy data.
Explicitly mandates authorizing remote access types before permitting connections, directly mitigating improper authorization.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Direct remote authorization bypass in a public-facing web application interceptor enables exploitation of the exposed service.
