CVE-2025-53503
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 · uneditedTrend Micro Cleaner One Pro is vulnerable to a Privilege Escalation vulnerability that could allow a local attacker to unintentionally delete privileged Trend Micro files including its own.
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 confidenceTrend Micro Cleaner One Pro contains a privilege escalation vulnerability where a local attacker can exploit the application's file deletion functionality to unintentionally delete privileged Trend Micro files, potentially including the application's own files. This likely stems from insufficient access control checks on the cleanup/deletion mechanism that runs with elevated privileges.

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.
-
Check installed version of Trend Micro Cleaner OneLocate the installed application and retrieve its version number - typically found in the program's properties, About dialog, or uninstall entry in Control Panel. Compare the version to the affected range: any version below 6.8.333 is vulnerable.Affected if The installed version is Trend Micro Cleaner One (any edition) and is below version 6.8.333
-
Confirm the application runs with elevated privilegesCheck the process properties of Cleaner One to determine if it executes with administrator or SYSTEM-level privileges. On Windows, right-click the process in Task Manager and view 'Run as administrator' status or check the service configuration if it runs as a Windows service.Affected if The application runs with elevated (administrator or SYSTEM) privileges, which is required for the privilege escalation to be exploitable
-
Verify the cleanup/deletion feature is presentLocate the cleanup or file deletion functionality within the application interface. This may be labeled as 'Cleaner', 'Quick Clean', 'File Shredder', or similar cleanup tools. Confirm the feature exists and is accessible.Affected if The cleanup/deletion feature is present and accessible, providing the attack vector for the vulnerability
-
Inspect file permissions on application directoriesReview permissions on the Trend Micro Cleaner One installation directory and subdirectories. Check if standard user accounts have write or delete permissions to files that the elevated application process can access.Affected if Non-privileged local users have write or delete permissions to application directories or files that the elevated process manages
You are affected if Trend Micro Cleaner One version is below 6.8.333 AND the application runs with elevated privileges with a cleanup/deletion feature that permits manipulation of privileged files by lower-privilege 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.
dbcve · scoped6.8.333
Apply vendor-supplied patches when available. Until then, restrict local user access to the application directories and monitor for suspicious file deletion activities. Consider running the application with minimal privileges if supported.
6.8.333 or later
- Verify current installed version of Trend Micro Cleaner One Pro
- Download Cleaner One version 6.8.333 or later from the official Trend Micro help center (helpcenter.trendmicro.com) or trusted download source
- Uninstall the current vulnerable version of Cleaner One
- Install the updated version (6.8.333 or later)
- Verify the installed version is 6.8.333 or higher
