CWE ID Description
CWE-1220 The product implements access controls via a policy or other feature with the intention to disable or restrict accesses (reads and/or writes) to assets in a system from untrusted agents. However, implemented access controls lack required granularity, which renders the control policy too broad because it allows accesses from unauthorized agents to the security-sensitive assets.

Executive Summary

This vulnerability is caused by insufficient granularity of access control in Microsoft Defender. It allows an authorized attacker to elevate their privileges locally on the affected system.

Impact Analysis

The impact of this vulnerability is an elevation of privilege, meaning an attacker who already has some level of access can gain higher privileges. This can lead to full control over the affected system, potentially allowing the attacker to execute arbitrary code, access sensitive data, or disrupt system operations.
