The attack requires local access. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

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.

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. Check if IObit Malware Fighter is installed
    Look for IObit Malware Fighter in the list of installed programs via Control Panel > Programs and Features, or use 'Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | Select-Object DisplayName, DisplayVersion' in PowerShell
    Affected if IObit Malware Fighter appears in the installed programs list
  2. Determine the installed version
    Run the application and check About/Help section for the version number, or inspect the executable's properties in the installation directory (typically C:\Program Files\IObit\IObit Malware Fighter\)
    Affected if The version is 13.2.0 or any earlier version up to and including 13.2.0
  3. Verify the DLL Handler component exists
    Check the IObit Malware Fighter installation directory for modules related to DLL handling, or examine the application's component list in the settings/interface
    Affected if The DLL Handler or similar DLL protection module is present in the installation
  4. Confirm DLL Handler is enabled
    Open IObit Malware Fighter interface and navigate to protection settings or DLL protection modules to see if the component is active
    Affected if The DLL Handler protection feature is turned on or configured in the application settings

A user is affected if IObit Malware Fighter version 13.2.0 or earlier is installed with the DLL Handler component enabled on the system.
