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 product versionOpen the Trend Micro application UI and navigate to Help > About, or check the installed programs list in Windows Control Panel to find the exact version number of Trend Micro Security or Maximum SecurityAffected if The installed version is exactly 17.8 (the only affected version per this CVE)
-
Confirm the product nameVerify the specific Trend Micro product installed: either Trend Micro Security or Trend Micro Maximum Security 2022Affected if The product is Trend Micro Maximum Security 2022 specifically at version 17.8
-
Check for Trend Micro installation directoryLocate the Trend Micro installation directory, typically found under C:\Program Files\Trend Micro\ or C:\Program Files (x86)\Trend Micro\ in default Windows installationsAffected if The product is installed and the version matches 17.8, making it vulnerable to symlink manipulation in the installation path
-
Assess local user accessReview local user accounts on the system to determine if untrusted or low-privilege users have access to the machineAffected if Untrusted local users have access to the system where Trend Micro Security 17.8 is installed, as the vulnerability requires local attacker access to manipulate symbolic links
A system is affected if Trend Micro Maximum Security 2022 version 17.8 is installed and untrusted local users can access the system to manipulate symlinks within the Trend Micro installation directories.

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 security patches when available. Until then, restrict local access to untrusted users and monitor for suspicious file system activity in the Trend Micro installation directories.
