CVE-2025-1789: Genetec Update Service Privilege Escalation

CVE-2025-1789 Overview

CVE-2025-1789 is a local privilege escalation vulnerability affecting the Genetec Update Service. An authenticated, low-privileged Windows user could exploit this vulnerability to gain elevated privileges on the affected system. The vulnerability is classified under CWE-276 (Incorrect Default Permissions), indicating that the service operates with insecure permission settings that can be leveraged by attackers with local access.

Critical Impact

Successful exploitation allows a low-privileged local user to escalate privileges to a higher security context, potentially gaining SYSTEM-level access on affected Windows systems running the vulnerable Genetec Update Service.

Affected Products

• Genetec Update Service (all versions prior to 2.10)
• Systems running Genetec security management software with the Update Service component
• Windows environments with the vulnerable service installed

Technical Details for CVE-2025-1789

Vulnerability Analysis

This vulnerability stems from incorrect default permissions (CWE-276) in the Genetec Update Service. The service, which runs with elevated privileges to manage software updates, does not properly restrict access to sensitive resources. This misconfiguration allows authenticated local users with limited privileges to interact with the service in unintended ways, ultimately enabling privilege escalation.

The local attack vector requires the attacker to have authenticated access to the Windows system where the Genetec Update Service is installed. While the attack complexity is noted as high with certain preconditions required, successful exploitation results in complete compromise of confidentiality, integrity, and availability of both the vulnerable system and potentially other connected systems.

Root Cause

The root cause is CWE-276: Incorrect Default Permissions. The Genetec Update Service operates with default permission settings that are overly permissive, failing to properly restrict which users can interact with the service or its associated resources. This could manifest through insecure service configuration, writable installation directories, or improper ACLs on service-related files and registry keys.

Attack Vector

The attack vector is local, meaning an attacker must have authenticated access to the target Windows system. The exploitation scenario involves a low-privileged user leveraging the incorrect permissions on the Genetec Update Service to execute code or commands in a higher privilege context. This could involve manipulating service binaries, configuration files, or exploiting the service's update mechanism to execute arbitrary code with elevated privileges.

The vulnerability requires the attacker to:

1. Gain authenticated access to a Windows system with Genetec Update Service installed
2. Identify the misconfigured permissions on service components
3. Exploit the permission weakness to inject or modify executable content
4. Trigger the service to execute the malicious payload with elevated privileges

Detection Methods for CVE-2025-1789

Indicators of Compromise

• Unexpected modifications to Genetec Update Service installation directories or binaries
• Suspicious processes spawned as child processes of the Genetec Update Service
• Unauthorized changes to service registry keys related to Genetec components
• Anomalous privilege escalation events on systems running the vulnerable service

Detection Strategies

• Monitor Windows Security Event logs for privilege escalation attempts (Event IDs 4672, 4673)
• Implement file integrity monitoring on Genetec Update Service directories
• Configure SentinelOne endpoint protection to detect process injection and privilege escalation techniques
• Audit service permission changes using Sysmon or similar endpoint monitoring tools

Monitoring Recommendations

• Enable detailed logging for Windows services, particularly update services
• Deploy behavioral detection rules for local privilege escalation patterns
• Monitor for unauthorized write operations to service directories by non-admin users
• Implement real-time alerting for suspicious service restarts or configuration changes

How to Mitigate CVE-2025-1789

Immediate Actions Required

• Update Genetec Update Service to version 2.10 or later immediately
• Audit current installations to identify affected systems in your environment
• Review and harden permissions on the Genetec Update Service installation directory
• Implement least-privilege access controls for users with local system access

Patch Information

Genetec has released security updates addressing this vulnerability in Genetec Update Service version 2.10. Organizations should apply this update as soon as possible to remediate the privilege escalation risk. For detailed patch information and download links, refer to the Genetec Security Update Bulletin.

Workarounds

• Restrict local access to systems running the Genetec Update Service to trusted administrators only
• Implement application whitelisting to prevent unauthorized executables from running in service directories
• Configure Windows security policies to audit and restrict service modifications
• Use network segmentation to isolate systems running vulnerable services until patching is complete

# Review current permissions on Genetec Update Service directory
icacls "C:\Program Files\Genetec\Update Service"

# Verify the service is running the patched version
