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 · unedited
A DLL hijacking vulnerability exists in the Trend Micro Security's 2019 consumer family of products (v15) Folder Shield component and the standalone Trend Micro Ransom Buster (1.0) tool in which, if exploited, would allow an attacker to load a malicious DLL, leading to elevated privileges.

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 · high confidence

A DLL hijacking vulnerability in Trend Micro Security 2019 v15 Folder Shield component and Trend Micro Ransom Buster 1.0 allows an attacker to load a malicious DLL by placing it in a location where the application searches for DLLs, resulting in elevated privileges.

MitigationApply vendor patches or update to a patched version of the affected Trend Micro products; ensure the application uses secure DLL loading mechanisms (e.g., full path specification or safe DLL search mode).

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed Trend Micro product and version
    Open Control Panel > Programs and Features, or use PowerShell: Get-ItemProperty 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\*' | Where-Object {$_.DisplayName -like '*Trend Micro*'} | Select-Object DisplayName, DisplayVersion
    Affected if The installed product is one of: Antivirus + Security 2019, Internet Security 2019, Maximum Security 2019, or Premium Security 2019, with DisplayVersion = 15.0; or Ransom Buster with DisplayVersion = 1.0
  2. Check if Folder Shield component is active
    Open Trend Micro main UI, navigate to Folder Shield settings, or check running processes for the Folder Shield module (typically named something like 'TMSSF.exe' or 'FolderShield.exe' depending on the product)
    Affected if Folder Shield component is enabled or running on the system
  3. Verify DLL loading behavior of Trend Micro process
    Use Process Explorer or Process Monitor from Sysinternals to monitor the Trend Micro security process (e.g., TMSSF.exe or core service) and check if it loads DLLs from user-writable directories without full path specification
    Affected if The Folder Shield process loads DLLs from locations with weak access controls or without using safe DLL search mode

You are affected if you have Trend Micro Security 2019 v15.0 or Ransom Buster v1.0 installed with the Folder Shield component enabled and the process exhibits unsafe DLL loading behavior.

Mitigation

Apply vendor patches or update to a patched version of the affected Trend Micro products; ensure the application uses secure DLL loading mechanisms (e.g., full path specification or safe DLL search mode).
