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 installed Trend Micro productCheck the system for installed Trend Micro endpoint protection software. On Windows, check Add/Remove Programs or look in Program Files for 'Trend Micro' or 'OfficeScan' directories. On macOS, check /Applications for Trend Micro applications.Affected if The product is Apex One 2019, OfficeScan XG, or Worry-Free Business Security versions 9.0, 9.5, or 10.0
-
Confirm product version numberLocate the exact version number of the installed Trend Micro agent. This is typically found in the agent's UI under About/Help, or in the registry under HKLM\SOFTWARE\TrendMicro\Deep Security Agent (or similar path depending on product).Affected if The version matches exactly 2019 for Apex One, XG for OfficeScan, or 9.0, 9.5, or 10.0 for Worry-Free Business Security
-
Verify client agent component is activeConfirm the Trend Micro client/agent component is installed and running. Check for the agent service (e.g., 'Trend Micro Security Agent' or 'OfficeScan NT Listener') in services.msc, or check for active processes like 'TMCCSF.exe', 'PccNTMon.exe', or 'vsapi.exe'.Affected if The agent client component is installed and running, indicating the vulnerable component is present
-
Check for unauthorized configuration changesReview the agent configuration for any unauthorized changes to content validation settings. This may be visible in the agent UI under 'Settings' or 'Policy', or by examining configuration files in the agent installation directory.Affected if Content validation settings have been modified or bypassed without administrator authorization
The environment is affected if a Trend Micro endpoint protection product is installed and matches exactly the affected versions (Apex One 2019, OfficeScan XG, or Worry-Free Business Security 9.0/9.5/10.0) with the client agent component present.

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 patches for this vulnerability to all affected Trend Micro agents. Since user authentication is required for exploitation, ensure credential hygiene and limit administrative access to the management console.
