Attack-Flow Graph

Executive Summary

This vulnerability is an incorrect access of an indexable resource, often called a 'range error,' in the Windows Sensor Data Service. It allows an authorized attacker with local access to elevate their privileges on the system.

Detection Guidance

Detection requires monitoring for unauthorized privilege escalation attempts in Windows Sensor Data Service. Check Windows Event Logs for unusual activity in 'Security' or 'System' logs, particularly Event ID 4624 (successful logons) and Event ID 4672 (special privileges assigned). Use PowerShell commands like 'Get-WinEvent -LogName Security | Where-Object {$_.Id -eq 4672}' to filter relevant events.

Impact Analysis

If exploited, this vulnerability could let an attacker gain higher-level permissions on your system, potentially allowing them to install programs, view or delete data, or create new accounts with full user rights.

Compliance Impact

This vulnerability could lead to unauthorized access or privilege escalation, which may violate compliance requirements for data protection standards like GDPR or HIPAA by exposing sensitive information or allowing unauthorized system changes.

Mitigation Strategies

Apply the latest security updates from Microsoft for Windows Sensor Data Service. Restrict local administrative privileges to prevent unauthorized access. Monitor for suspicious activity in the service logs and disable the service if not required.
