Executive brief
A security vulnerability exists in Windows Management Services, a core component used for managing and monitoring Windows systems. An attacker who already has basic access to a computer could exploit this flaw to gain full administrative control over the system. This could lead to the theft of sensitive data, installation of malicious software, or complete disruption of the affected machine.
Technical details
This vulnerability is classified as a race condition (CWE-362) within Windows Management Services, potentially involving memory safety issues such as Double Free (CWE-415) or Use After Free (CWE-416). The attack requires local access with low privileges (PR:L) and involves a high degree of complexity (AC:H) to successfully time the concurrent execution against shared resources. If successfully exploited, the attacker can achieve a scope change (S:C), gaining full SYSTEM-level privileges. Microsoft has released security updates to address this issue across various versions of Windows 10, Windows 11, and Windows Server.
