Technical details
A privilege escalation vulnerability exists in Microsoft Dynamics 365 due to improper access control (CWE-284). An attacker must be authenticated to the network with low-privileged credentials to exploit this flaw. By sending specially crafted requests to the Dynamics 365 service, the attacker can bypass authorization checks to gain administrative-level access. The vulnerability has a high impact on confidentiality, integrity, and availability, and notably involves a 'Scope' change in the CVSS metric, suggesting the attacker may be able to impact components beyond the initial security scope. Microsoft has addressed this in their security update guide.
