Executive Summary

This vulnerability involves incorrect permission assignment for a critical resource in the Windows Accessibility Infrastructure component called ATBroker.exe.

Because of this misconfiguration, an authorized attacker who already has some level of access on the system can exploit this flaw to elevate their privileges locally.

Impact Analysis

The vulnerability allows an attacker with existing local access to increase their privileges, potentially gaining higher-level permissions than intended.

This can lead to full control over the affected system, enabling the attacker to execute arbitrary code, access sensitive data, or disrupt system operations.
