Vulnerability Data
Incorrect Authorization (CWE-863) in Elastic Defend can lead to unauthorized information disclosure via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). Under certain conditions, a low-privileged authenticated user can access response action data that they are not authorized to view.

Why these techniques?
Improper authorization (CWE-863) directly enables a low-privileged user to read response action data stored locally that should be restricted, mapping to unauthorized data access from the local system.

Mitigating Controls (NIST 800-53 r5) AI
Directly enforces authorization policies to block low-privileged users from accessing response action data they are not permitted to view.
Limits privileges of authenticated users so that even under misconfigured authorization they cannot reach unauthorized response data.
Enforces information flow rules that would stop unauthorized disclosure of response action data between privilege domains.

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.
Enforcing policy-driven approval and role-change reviews stops incorrect or stale authorization decisions from remaining in effect after job changes or terminations.
By tying access rights to identity, device, location and classification, the control reduces the likelihood that an authorization decision will be based on an incorrect or bypassed policy.
