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.
-
Identify if ThreatSonar Anti-Ransomware is installedCheck for the product installation directory, service, or running process named 'Threatsonar' or 'TeamT5' on the system. Look in common installation paths or check installed programs list.Affected if The product TeamT5 Threatsonar Anti-Ransomware is found on the system
-
Determine the installed versionLocate the version information file, check the product about page via the web interface, or use the product's CLI tool if available. Compare the version number against the affected range (anything below 4.0.0).Affected if The installed version is below 4.0.0
-
Check if web interface is enabledVerify whether the ThreatSonar web management interface is accessible by attempting to reach the default web port (typically 443 or 8443) or checking the service configuration for web server status.Affected if The web interface is accessible and the version is below 4.0.0
-
Verify authentication configurationReview user accounts configured for ThreatSonar web access and confirm whether weak or default credentials are in use. Check if the authentication mechanism allows remote access.Affected if Remote web access is permitted with authenticated accounts and version is below 4.0.0
-
Inspect access logs for suspicious file deletion activityReview ThreatSonar web access logs for requests containing '../' path traversal patterns, especially those targeting system directories or multiple file deletion operations.Affected if Logs show path traversal patterns in web requests and the product version is below 4.0.0
The environment is affected if TeamT5 Threatsonar Anti-Ransomware version below 4.0.0 is installed with its web interface accessible to authenticated 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 data4.0.0
Apply vendor-supplied patches immediately, restrict web access to trusted users only, and audit access logs for suspicious file deletion activity.
