IIS 4.0 and 5.0 does not properly perform ISAPI extension processing if a virtual directory is mapped to a UNC share, which allows remote attackers to read the source code of ASP and other files, aka the "Virtualized UNC Share" vulnerability.

Security readout for executives and security teams

This is a legacy Microsoft IIS issue where certain web directories pointing to network shares could expose ASP or other source files to remote users. The main business risk is disclosure of application source code, embedded secrets, or logic that could support later compromise. Exposure is likely limited to legacy IIS 4.0 or 5.0 systems with virtual directories mapped to UNC shares. Modern systems are not identified in the provided sources. Treat this as a legacy exposure cleanup item unless an affected IIS server is internet-facing or contains sensitive code. Prioritize discovery because old systems often lack compensating controls and may hold embedded credentials. Mitigation focus: Inventory IIS 4.0 and 5.0 systems still in service.; Identify virtual directories mapped to UNC network shares.; Review Microsoft MS00-019 and Q249599 for official remediation guidance..
