MITRE ATT&CK Enterprise TechniquesAI

T1068 Exploitation for Privilege Escalation Privilege Escalation
Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.
T1098 Account Manipulation Persistence
Adversaries may manipulate accounts to maintain and/or elevate access to victim systems.
T1531 Account Access Removal Impact
Adversaries may interrupt availability of system and network resources by inhibiting access to accounts utilized by legitimate users.
Why these techniques?

IDOR improper authorization in deleteBatch endpoint enables low-privileged users to perform unauthorized batch account deletion/reset, facilitating exploitation for privilege escalation (T1068), account manipulation (T1098), and account access removal (T1531).

addresses: CWE-285 CWE-266

Documented procedures facilitate correct implementation and ongoing management of authorization decisions.

addresses: CWE-285 CWE-266

Periodic reviews identify and correct flaws in authorization decisions or enforcement.

addresses: CWE-285 CWE-266

Specifying access authorizations for each account and requiring approvals for account requests enforces proper authorization decisions.

addresses: CWE-266 CWE-285

The control requires explicit definition of separated access authorizations, making incorrect privilege assignments that bundle conflicting duties harder to implement.

addresses: CWE-266 CWE-285

Ensures privileges are assigned only as necessary rather than incorrectly over-granted.

addresses: CWE-285

The control's documentation requirement reduces improper authorization by ensuring only mission-justified actions bypass authentication.

addresses: CWE-285

Establishing permitted attributes and values, plus auditing changes, ensures authorization decisions are based on correctly managed policy data.

addresses: CWE-285

Explicitly mandates authorizing remote access types before permitting connections, directly mitigating improper authorization.
