MITRE ATT&CK Enterprise TechniquesAI

T1068 Exploitation for Privilege Escalation Privilege Escalation
Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.
Why these techniques?

Incorrect authorization (CWE-863) on a high-privileged local account directly enables unauthorized command execution, mapping to exploitation for privilege escalation.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly enforces authorization decisions to block the incorrect authorization flaw (CWE-863) that permits unauthorized command execution.

prevent

Limits privileges of local high-privileged accounts so that even a successful authorization bypass yields minimal command-execution capability.

prevent

Ensures access-control decisions are made by a reference monitor rather than relying on the flawed application logic in the affected Dell releases.

PR.AA-05 mostly match
prevents

Defining, enforcing, and reviewing access authorizations and least privilege directly prevents incorrect 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 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.

prevents

Enforcing policy-driven approval and role-change reviews stops incorrect or stale authorization decisions from remaining in effect after job changes or terminations.

prevents

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.
