Why use FrontPage extensions?

Microsoft FrontPage simplifies web authoring, managing, and serving tasks. The extensions work through CGI (Common Gateway Interface), ISAPI (Internet Server Application Program Interface), and HTTP.

They allow the Microsoft FrontPage client to transfer and manage files directly without FTP.

They also enable FrontPage-specific features to website visitors' browsers with no additional coding required by the developer.

What are FrontPage server extension vulnerabilities?
  • Cross-site scripting (XSS) vulnerability in _vti_bin/_vti_adm/fpadmdll.dll can allow remote attackers to execute
    arbitrary code or create new accounts.
  • SmartHTML interpreter (shtml.dll) vulnerability can cause denial of service due to specific requests.
  • Buffer overflow in shtml.dll may allow DoS attacks or remote code execution.
Solution:

Disable FrontPage Extensions:
