Security readout for executives and security teams
A flaw in the Indexing Services shipped with Windows 2000 IIS 5.0 lets an attacker craft a malicious link that, when clicked, causes a trusted company web page to reflect attacker-supplied content back to the visitor. The risk is browser-side trickery such as fake login prompts or session hijacking, not direct server takeover. Microsoft addressed this in security bulletin MS00-084 in 2000. Only legacy Windows 2000 hosts running IIS 5.0 with Indexing Services and the .htw handler enabled are affected. Any such system reachable today is far outside vendor support and almost certainly already retired or isolated in modern environments. Low priority for modern estates. Elevate only if an inventory review surfaces a surviving Windows 2000 IIS 5.0 host, in which case decommissioning that platform matters more than patching this single CVE. Mitigation focus: Apply the Microsoft MS00-084 patch on any remaining Windows 2000 IIS 5.0 host.; Unmap the .htw ISAPI extension in IIS if Indexing Services web hits are not required.; Retire or isolate end-of-life Windows 2000 and IIS 5.0 systems from public networks..
