IIS 4.0 and Site Server 3.0 allow remote attackers to read source code for ASP files if the file is in a virtual directory whose name includes extensions such as .com, .exe, .sh, .cgi, or .dll, aka the "Virtual Directory Naming" vulnerability.

Affected Software

3 affected components
Microsoft Internet Information Server=4.0
Microsoft Site Server=3.0

Remediation

Recommended actions to resolve this vulnerability, in priority order.

  1. Configuration

    Rename or remove any virtual directories whose names include file-extension-like substrings (for example ".com", ".exe", ".sh", ".cgi", ".dll"); ensure ASP files are not stored in virtual directories with those names to prevent source disclosure.

    Microsoft Internet Information Services (IIS) 4.0 virtual directory naming = do not use names containing extensions such as .com, .exe, .sh, .cgi, .dll
  2. Configuration

    On systems integrating Commerce Server or Site Server Commerce with IIS, ensure virtual directory names do not include extensions like ".com", ".exe", ".sh", ".cgi", or ".dll"; rename or remove such directories and relocate any ASP files.

    Microsoft Commerce Server / Microsoft Site Server Commerce virtual directory naming = do not use names containing extensions such as .com, .exe, .sh, .cgi, .dll
  3. Operational

    Audit affected servers (IIS 4.0, Site Server 3.0, and systems running Microsoft Commerce Server / Site Server Commerce) for virtual directory names containing ".com", ".exe", ".sh", ".cgi", or ".dll" and remediate by renaming/removing directories and relocating ASP files; repeat audit after changes to confirm remediation.
