Actively exploited zero-day in IIS 6.0 affects 60,000+ servers

Microsoft Internet Information Services (IIS) 6.0 sports a zero-day vulnerability (CVE-2017-7269) that was exploited in the wild last summer and is likely also being exploited by threat actors at this very moment. It is a buffer overflow flaw in a function in the WebDAV service in IIS 6.0 in Microsoft Windows Server 2003 R2, and can be triggered by attackers sending a overlong IF header in a PROPFIND request.
