Executive Summary

[{'type': 'paragraph', 'content': 'CVE-2019-25304 is an unquoted service path vulnerability in the SecurosCtrlService of Intelligent Security System\'s SecurOS Enterprise version 10.2. The service path "C:\\Program Files (x86)\\ISS\\SecurOS\\" is not enclosed in quotes, which allows local users to insert malicious executables or code into the path.'}, {'type': 'paragraph', 'content': 'When the service starts, the operating system may execute the malicious code with elevated system-level privileges, leading to potential privilege escalation.'}] [2, 3]

Detection Guidance

[{'type': 'paragraph', 'content': "This vulnerability can be detected by checking for unquoted service paths in the Windows services, specifically the 'SecurosCtrlService' service path."}, {'type': 'paragraph', 'content': 'You can use Windows command line tools to identify unquoted service paths. For example, running the following command in an elevated command prompt will list services and their executable paths:'}, {'type': 'list_item', 'content': 'sc qc SecurosCtrlService'}, {'type': 'paragraph', 'content': 'If the path returned is unquoted and contains spaces (such as C:\\Program Files (x86)\\ISS\\SecurOS\\securos_svc.exe), it indicates the presence of this vulnerability.'}, {'type': 'paragraph', 'content': 'Additionally, you can search all services for unquoted paths by running a PowerShell command like:'}, {'type': 'list_item', 'content': 'Get-WmiObject win32_service | where { $_.PathName -like \'* *\' -and $_.PathName -notlike \'"*"\' } | select Name, PathName'}, {'type': 'paragraph', 'content': 'This command lists all services with spaces in their executable path that are not enclosed in quotes, helping to detect similar unquoted service path vulnerabilities.'}] [2, 3]

Mitigation Strategies

[{'type': 'paragraph', 'content': 'To mitigate this vulnerability, the immediate step is to correct the unquoted service path by enclosing the entire executable path in double quotes.'}, {'type': 'paragraph', 'content': "For the 'SecurosCtrlService', update the service path from:"}, {'type': 'list_item', 'content': 'C:\\Program Files (x86)\\ISS\\SecurOS\\securos_svc.exe'}, {'type': 'paragraph', 'content': 'to:'}, {'type': 'list_item', 'content': '"C:\\Program Files (x86)\\ISS\\SecurOS\\securos_svc.exe"'}, {'type': 'paragraph', 'content': 'This can be done using the Windows Registry Editor or by using the command line with administrative privileges.'}, {'type': 'paragraph', 'content': 'Additionally, ensure that only trusted users have write permissions to directories in the service path to prevent insertion of malicious executables.'}, {'type': 'paragraph', 'content': 'Restart the service or reboot the system after applying the fix to ensure the corrected path is used.'}] [2, 3]
