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
Web View in Windows Explorer on Microsoft Windows 2000 SP4, XP SP1 and SP2, and Server 2003 does not properly handle certain HTML characters in preview fields, which allows remote user-assisted attackers to execute arbitrary code.

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

Windows Explorer Web View feature fails to properly sanitize HTML characters in preview fields, allowing injection of malicious HTML/scripts that can be triggered when users preview crafted files, leading to arbitrary code execution. This is a user-assisted attack requiring the victim to preview a specially crafted file.

MitigationApply Microsoft security updates MS05-044 or later, or upgrade from unsupported Windows versions (2000/XP/Server 2003) to supported operating systems as these legacy platforms are no longer patchable.

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 Windows version
    Run 'winver' or check System Properties to determine the Windows version. Affected systems are Windows 2000, Windows XP, Windows 2003 Server R2, or any Windows version with Windows Explorer.
    Affected if The system is running Windows 2000, Windows XP, Windows Server 2003 R2, or an older Windows Explorer version that has not been patched.
  2. Confirm WebView preview feature is enabled
    Open Windows Explorer, look for the preview pane (typically on the right side of the window in older Explorer versions) or check if selecting a file shows its contents in a preview window. In Windows XP/2003, this is the 'WebView' feature accessible via View menu.
    Affected if The WebView preview pane is enabled and operational, allowing HTML content to be rendered when previewing files.
  3. Check if MS05-044 update is installed
    Open Control Panel > Add or Remove Programs, check 'Show updates', and look for 'Security Update for Windows (MS05-044)' in the installed updates list. Alternatively, run 'wmic qfe list' or check Windows Update history.
    Affected if MS05-044 security update is NOT installed - the system is unpatched and vulnerable.
  4. Verify Explorer version and patch level
    Right-click onExplorer executable (typically in C:\Windows or C:\Windows\System32), select Properties, and check the File Version. Compare against the version that includes the MS05-044 fix.
    Affected if The Windows Explorer executable version predates the MS05-044 fix or the file is unpatched.

A system is affected if it runs Windows 2000, XP, or Server 2003 R2 (or an older Windows Explorer) AND has the WebView preview feature enabled AND is missing the MS05-044 security update.
