Detection Guidance

[{'type': 'paragraph', 'content': "This vulnerability can be detected by checking the service configuration for unquoted service paths. Specifically, you can query the Windows service named 'NGDatBckpSrv' to see if its executable path is unquoted."}, {'type': 'list_item', 'content': 'Run the command: sc qc NGDatBckpSrv'}, {'type': 'paragraph', 'content': 'If the output shows the binary path without quotes around the path containing spaces (e.g., C:\\Program Files\\NETGATE\\Data Backup\\DataBackupSrv.exe), the system is vulnerable to this unquoted service path issue.'}] [1]

Executive Summary

CVE-2019-25271 is an unquoted service path vulnerability found in NETGATE Data Backup version 3.0.620, specifically in the Windows service named NGDatBckpSrv.

Because the service path contains spaces and is not enclosed in quotes, Windows may incorrectly parse the executable path.

An attacker with local access can exploit this by placing malicious executable files in certain directories along the service path, causing Windows to execute the malicious code instead of the intended service binary.

This allows the attacker to execute arbitrary code with LocalSystem privileges, effectively escalating their privileges on the system.

Impact Analysis

This vulnerability can lead to local privilege escalation, allowing an attacker with local access to execute arbitrary code with LocalSystem privileges.

As a result, the attacker can gain full control over the affected system, compromising its confidentiality, integrity, and availability.

• Execution of malicious code with elevated privileges
• Full system compromise
• Potential unauthorized access to sensitive data
• Disruption or manipulation of system operations

Mitigation Strategies

[{'type': 'paragraph', 'content': 'Immediate mitigation involves correcting the service path by enclosing it in quotes to prevent Windows from misinterpreting the path and executing malicious code.'}, {'type': 'paragraph', 'content': "You should update the service configuration for 'NGDatBckpSrv' to ensure the executable path is properly quoted."}, {'type': 'paragraph', 'content': 'Additionally, restrict local user permissions to prevent unauthorized users from placing executables in directories that could be exploited.'}, {'type': 'paragraph', 'content': 'If available, apply any vendor patches or updates that address this vulnerability.'}] [2]
