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
Microsoft Windows Media Player 6.4, Windows Media Format Runtime 7.1 through 11, and Windows Media Services 4.1 and 9 incorrectly associate ISATAP addresses with the Local Intranet zone, which allows remote servers to capture NTLM credentials, and execute arbitrary code through credential-reflection attacks, by sending an authentication request, aka "ISATAP Vulnerability."

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 Media Player and Windows Media Services incorrectly classify ISATAP (Intra-Site Automatic Tunnel Addressing Protocol) addresses as belonging to the Local Intranet zone instead of the Internet zone. This misclassification causes the system to send NTLM credentials automatically during authentication attempts, allowing remote attackers to capture these credentials and perform credential-reflection attacks to execute arbitrary code.

MitigationApply the relevant Microsoft security update (MS08-076) to affected Windows Media components. Additionally, consider disabling NTLM authentication or implementing EPA (Extended Protection Authentication) to mitigate credential theft attacks.

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 Windows Media Player version
    Open Windows Media Player, go to Help > About Windows Media Player. The version number is displayed there.
    Affected if The installed version is exactly 6.4 (9.0.0.6.4)
  2. Check if ISATAP tunneling is enabled
    Run 'netsh interface isatap show state' from an elevated command prompt to display ISATAP interface status.
    Affected if ISATAP state shows as enabled or the ISATAP tunnel adapter is present in 'ipconfig /all' output
  3. Verify ISATAP router is configured
    Run 'netsh interface isatap show router' to check if an ISATAP router address is configured.
    Affected if A router address is configured and reachable, indicating ISATAP is actively in use
  4. Check NTLM authentication settings
    Review group policy settings under Computer Configuration > Windows Settings > Security Settings > Local Policies > Security Options for 'Network security: LAN Manager authentication level'.
    Affected if Authentication level is set to 'Send NTLM response only' or lower (allows NTLM credential transmission)

A system is affected if Windows Media Player 6.4 is installed, ISATAP is enabled/active on the network, and NTLM authentication is permitted, allowing automatic credential submission to ISATAP addresses.
