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
Trend Micro Security 2021, 2022, and 2023 (Consumer) are vulnerable to a DLL Hijacking vulnerability which could allow an attacker to use a specific executable file as an execution and/or persistence mechanism which could execute a malicious program each time the executable file is started.

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 confidence

Trend Micro Security 2021-2023 consumer products contain a DLL hijacking vulnerability where an attacker can place a malicious DLL in a location where a specific Trend Micro executable will load it upon execution, achieving arbitrary code execution and persistence.

MitigationUpdate to the latest patched version of Trend Micro Security or remove/block the vulnerable executable if immediate patching is not feasible.

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 Security product
    Open Windows Control Panel > Programs and Features, or run 'Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | Select-Object DisplayName, DisplayVersion' in PowerShell to list installed programs
    Affected if No Trend Micro Security product appears in the installed programs list (not affected)
  2. Verify the exact version number
    Locate the installed Trend Micro Security application in Programs and Features and note the version column, or right-click the main Trend Micro executable and view Properties > Details
    Affected if The version number matches or is lower than 17.0.1412 for 2021 products, or 17.7.1476 for 2022 products
  3. Confirm the specific product edition
    Check the program name in Programs and Features: look for Antivirus+ Security, Internet Security, Maximum Security, or Premium Security
    Affected if The installed product is any of the four affected 2021 or 2022 editions listed in the affected products
  4. Locate the Trend Micro program directory
    Navigate to C:\Program Files\Trend Micro or C:\Program Files (x86)\Trend Micro and identify the main product executable folder
    Affected if The product directory exists and contains executable files
  5. Inspect for unauthorized DLLs in the product directory
    Examine the Trend Micro program folder for any DLL files that were not part of a legitimate installation, or compare the directory contents against a known-clean baseline
    Affected if Unexpected or unknown DLL files are present in the Trend Micro product directory alongside the main executable

The environment is affected if any Trend Micro Security 2021 (version <= 17.0.1412) or 2022 (version <= 17.7.1476) consumer product is installed, and an attacker could place a malicious DLL in the product directory where the vulnerable executable would load it.

Upgrade available Upgrade to a release after 17.7.1476
Interim mitigation

Update to the latest patched version of Trend Micro Security or remove/block the vulnerable executable if immediate patching is not feasible.

Recommended fix Moderate confidence

Latest available 2021/2022/2023 version of your specific Trend Micro consumer product (contact Trend Micro support for exact build numbers)

  1. Navigate to the official Trend Micro Help Center at helpcenter.trendmicro.com to locate the latest security updates for your specific product (Antivirus+, Internet Security, Maximum Security, or Premium Security)
  2. Identify your current installed version by opening the Trend Micro main console and checking 'About' or 'License' information
  3. Download and install the most recent version available for your 2021 or 2022 product, which should contain the security fix for the DLL hijacking vulnerability (CVE-2023-28929)
  4. After installation, verify the version has been updated to confirm the patch was applied successfully
  5. Alternatively, ensure your Trend Micro product is set to automatically receive security updates and patches
Caveat Standard upgrade considerations apply - ensure compatibility with your operating system and backup important data before updating
