Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly mitigates the privilege escalation vulnerability by requiring timely identification, reporting, and patching as detailed in Huawei's security bulletin.
Enforces least privilege to restrict low-privileged local users from escalating access in the Account module, limiting confidentiality impact.
Mandates enforcement of approved access authorizations, countering the business logic error enabling privilege escalation without changing scope.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Explicit local privilege escalation vulnerability in Account module enables T1068 Exploitation for Privilege Escalation from low-privileged local access.
NVD Description
Privilege escalation vulnerability in the Account module Impact: Successful exploitation of this vulnerability may affect service confidentiality.
