CVE-2025-60865 Overview
CVE-2025-60865 is an Insecure Permissions vulnerability discovered in avanquest Driver Updater v.9.1.57803.1174. The vulnerability allows a local attacker to escalate privileges via the Driver Updater Service Windows component. This type of flaw occurs when system services run with elevated permissions but fail to properly restrict access to their configuration, directories, or executable files, enabling unauthorized users to manipulate the service for malicious purposes.
Critical Impact
Local attackers can exploit this vulnerability to escalate privileges to SYSTEM level, potentially gaining complete control over the affected Windows system.
Affected Products
- avanquest Driver Updater v.9.1.57803.1174
- PCHelpsoft Driver Updater (related product)
- Windows systems running vulnerable Driver Updater Service

Technical Details for CVE-2025-60865
Vulnerability Analysis
This vulnerability falls under CWE-284 (Improper Access Control), which describes flaws where software fails to properly restrict access to resources. In the context of the Driver Updater Service, the insecure permissions allow local users with limited privileges to interact with or modify the service in unintended ways.
The local attack vector means an attacker must have some level of access to the target system, but the low complexity and no user interaction required make this vulnerability straightforward to exploit once access is obtained. Successful exploitation leads to high impact across confidentiality, integrity, and availability—effectively granting the attacker full control over the compromised system.
Root Cause
The root cause of this vulnerability is improper access control implementation in the Driver Updater Service Windows component. The service likely has one or more of the following issues:
- Weak permissions on the service executable or its installation directory, allowing modification by unprivileged users
- Insecure service configuration that permits unauthorized users to change service properties
- Overly permissive Access Control Lists (ACLs) on registry keys associated with the service
- Writable paths in the service's executable search order
Attack Vector
The attack vector is local, requiring the attacker to have an authenticated session on the target Windows system. The exploitation flow typically involves:
- Identifying the Driver Updater Service and its associated files, directories, or registry entries
- Analyzing the permissions to find writable locations that the service trusts
- Modifying the service binary, injecting a malicious DLL, or altering service configuration
- Triggering a service restart or waiting for system reboot to execute the malicious payload with elevated privileges

Detection Methods for CVE-2025-60865
Indicators of Compromise
- Unexpected modifications to the Driver Updater Service executable or associated DLL files
- Changes to registry keys under HKLM\SYSTEM\CurrentControlSet\Services\ related to the Driver Updater Service
- New or modified files in the Driver Updater installation directory with recent timestamps
- Suspicious process execution spawned from the Driver Updater Service context
Detection Strategies
- Monitor file integrity of the Driver Updater installation directory using endpoint detection solutions
- Audit Windows service configuration changes, particularly for services running as SYSTEM
- Deploy behavioral detection rules that alert on privilege escalation patterns from standard user to SYSTEM
- Implement SIEM rules to correlate local authentication events with subsequent service modifications
Monitoring Recommendations
- Enable Windows Security Event logging for service configuration changes (Event ID 7040)
- Monitor for process creation events where parent process is the Driver Updater Service and child process is unexpected
- Track file system changes in C:\Program Files\ and related application directories
- Review scheduled tasks and startup items for persistence mechanisms following exploitation
How to Mitigate CVE-2025-60865
Immediate Actions Required
- Audit the Driver Updater Service installation to verify current permissions on executable files, directories, and registry keys
- Restrict access to the Driver Updater installation directory to Administrators and SYSTEM only
- Consider disabling or uninstalling the Driver Updater Service if not critical to operations until a patch is available
- Implement application allowlisting to prevent unauthorized executables from running in service directories
Patch Information
No vendor patch information is currently available. Users should monitor the PCHelpsoft Driver Updater Page for security updates. Check the GitHub CVE Disclosures Repository for additional remediation guidance from the security researcher.
Workarounds
- Remove write permissions for standard users on the Driver Updater installation directory and all child objects
- Configure the service to run under a less privileged account if functionality permits
- Use Windows Defender Application Control (WDAC) or AppLocker to restrict executable modifications in the service directory
- Implement the principle of least privilege across all user accounts to limit local attack surface
