Executive Summary

This vulnerability is an improper privilege management issue in the log rotation mechanism of the Skylight Workspace Config Service in Amazon WorkSpaces for Windows versions before 2.6.2034.0.

It allows a local non-administrative authenticated user to place arbitrary files into arbitrary locations on the file system, bypassing normal file system permission protections.

This can lead to local privilege escalation, allowing the attacker to gain SYSTEM-level privileges.

Impact Analysis

The vulnerability can allow a local non-admin user to escalate their privileges to SYSTEM level on the affected system.

This means an attacker with limited access could gain full control over the system, potentially leading to unauthorized access, data manipulation, or disruption of services.
