CVE-2024-38182Network attack vector

Unauthenticated privilege escalation

Published Jul 31, 2024 · Updated Feb 10, 2026

Weak authentication in Microsoft Dynamics 365 Field Service (on-premises) v7 allows remote attackers to elevate privileges over a network. Microsoft has not published the affected authentication component or the operation that incorrectly accepts an unauthenticated request. Exploitation requires no credentials or user interaction but has high attack complexity and grants privileges across a changed security boundary.
