Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

AC-6 Least Privilege good match

prevent

Employs least privilege to directly counter improper privilege management (CWE-269), preventing escalation via the AccessID parameter.

AC-3 Access Enforcement good match

prevent

Enforces approved authorizations, blocking unauthorized privilege escalation through manipulation of the AccessID parameter.

SI-10 Information Input Validation good match

prevent

Validates the AccessID parameter input to prevent remote attackers from tampering with it to achieve privilege escalation.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
