CVE-2018-5199
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 · uneditedIn Veraport G3 ALL on MacOS, due to insufficient domain validation, It is possible to overwrite installation file to malicious file. A remote unauthenticated attacker may use this vulnerability to execute arbitrary file.
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 · moderate confidenceVeraPort G3 ALL on MacOS contains an insufficient domain validation vulnerability that allows a remote unauthenticated attacker to overwrite installation files with malicious files during the download process. This enables arbitrary file execution on the affected system.

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.
-
Locate VeraPort G3 installation on the systemSearch for the VeraPort G3 application in common MacOS installation directories such as /Applications and ~/Applications, or check for the application bundle named 'VeraPort G3' or similar naming conventionsAffected if VeraPort G3 application is present on the system
-
Identify the installed version of VeraPort G3Right-click the VeraPort G3 application and select 'Get Info', or use the command 'mdls' or system_profiler to retrieve the application version. Compare the version against the affected range (all versions are affected)Affected if Any version of VeraPort G3 is installed, since all versions are vulnerable
-
Determine if automatic download or update features are enabledExamine the VeraPort G3 preferences or configuration settings for options related to automatic updates, automatic downloads, or silent installation featuresAffected if Automatic download or update functionality is enabled, allowing the vulnerable download process to occur
-
Inspect configuration files for domain validation settingsLocate and examine VeraPort G3 configuration files (typically stored in Application Support or preferences directories) for settings controlling which domains are trusted for downloads and updatesAffected if Domain validation is configured to accept any source or lacks strict domain verification
-
Check for running processes related to VeraPort G3Use Activity Monitor or the 'ps' command to check if VeraPort G3 or related update services are actively running on the systemAffected if VeraPort G3 processes are running and the vulnerable update mechanism is active
If VeraPort G3 is installed and its automatic download or update feature is enabled, the system is affected by this insufficient domain validation vulnerability that allows man-in-the-middle attackers to inject malicious files during the update process.

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 dataApply vendor-provided patches for VeraPort G3. If no patch is available, implement network-level controls such as TLS-inspecting proxies, DNS filtering, or network segmentation to prevent man-in-the-middle attacks against the software update mechanism.
