CVE-2023-39464
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedTriangle MicroWorks SCADA Data Gateway GTWWebMonitorService Unquoted Search Path Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute code on affected installations of Triangle MicroWorks SCADA Data Gateway. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the configuration of the GTWWebMonitorService service. The path to the service executable contains spaces not surrounded by quotations. An attacker can leverage this vulnerability to execute arbitrary code in the context of root. Was ZDI-CAN-20538.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceTriangle MicroWorks SCADA Data Gateway contains an unquoted service path vulnerability in the GTWWebMonitorService. The service executable path contains unquoted spaces, allowing an attacker to hijack the path and execute arbitrary code in the context of root. Although authentication is required, it can be bypassed.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify if GTWWebMonitorService existsOpen Services console (services.msc) or run `sc query GTWWebMonitorService` in an elevated command promptAffected if The service is present on the system
-
Inspect the service executable pathRun `sc qc GTWWebMonitorService` to query the service configuration and examine the BINARY_PATH_NAME fieldAffected if The BINARY_PATH_NAME contains spaces and is not enclosed in quotation marks
-
Check for path hijacking opportunitiesExamine the directory paths in the unquoted service path - verify file system permissions on each directory component to see if low-privilege users can write to any intermediate folderAffected if Any directory in the path (excluding the final executable folder) is writable by non-admin users
-
Determine installed SCADA Data Gateway versionOpen Windows Programs and Features (appwiz.cpl) and locate Triangle MicroWorks SCADA Data Gateway, or check the version in the product's installation directory if accessibleAffected if Installed version is exactly 5.1.3.20324
You are affected if GTWWebMonitorService is installed with an unquoted path containing spaces and your installed version is 5.1.3.20324, especially if intermediate path directories are writable by standard users.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataEnclose the service executable path in quotes in the Windows service configuration for GTWWebMonitorService. This prevents path hijacking through the unquoted spaces.
