Exploits & Vulnerabilities
Hello, and welcome to the forum. I used FrontPage 2000 in the past but I never worked with frames when using FrontPage. The general thinking of ComputerHope forum members who are familiar with web design is not favorable toward use of FrontPage; they lean toward other web creation software or, indeed, toward raw coding with a simple text editor such as Notepad. Microsoft Works Word 97 If that one doesn't work for you, try this: 80 This key has been used successfully with: Access 97 Front Page 98 Office 97 Pro Outlook 98 Project 98 Publisher 98, English, Spanish Version Visual Basic 5.0 Professional and Enterprise Edition Word 97.

- Frontpage server extensions for iis 6.0 I have windows 7 professional installed, including the iis manager, which I think is 6.0. I am trying to run a website that needs the frontpage server extensions for full functionality (it was built using frontpage 2000 under Windows 2003).
Microsoft Internet Information Services (IIS) 6.0 is vulnerable to a zero-day Buffer Overflow vulnerability (CVE-2017-7269) due to an improper validation of an ‘IF’ header in a PROPFIND request.
Microsoft Internet Information Services (IIS) 6.0 is vulnerable to a zero-day Buffer Overflow vulnerability (CVE-2017-7269) due to an improper validation of an ‘IF’ header in a PROPFIND request
A remote attacker could exploit this vulnerability in the IIS WebDAV Component with a crafted request using PROPFIND method. Successful exploitation could result in denial of service condition or arbitrary code execution in the context of the user running the application. According to the researchers who found this flaw, this vulnerability was exploited in the wild in July or August 2016. It was disclosed to the public on March 27. Other threat actors are now in the stages of creating malicious code based on the original proof-of-concept (PoC) code.
What is WebDAV?
Web Distributed Authoring and Versioning (WebDAV) is an extension of the HTTP protocol that allows clients to perform remote Web content authoring operations. WebDAV extends the set of standard HTTP methods and headers allowed for the HTTP request. Few example of WebDAV methods are COPY, LOCK, MKCOL, PROPFIND, UNLOCK etc.
This vulnerability is exploited using the PROPFIND method and IF header. The PROPFIND method retrieves properties defined on the resource identified by the Request-URI. All the WebDAV-Compliant resources must support the PROPFIND method.
The IF header handles the state token as well as the ETags. It makes the request conditional by supplying a series of state lists with conditions that match tokens and ETags to specific resource. If all states present in the IF header fail, the request fails with 412 (Precondition Failed) status.
A simple PROPFIND request is shown below:

An example of a typical syntax of IF header:
If: <http://www.example.com/resource1> (<locktoken:Test1>) (['ETag']) <http://www.example.com/random>(['ETag'])
Vulnerability Description
This is a typical buffer overflow vulnerability . The affected system reported (by the researcher) is Windows 2003 and IIS version 6. The vulnerability could be exploited with an overly large ‘IF’ header in the ‘PROPFIND’ request with at least two http resource in the IF header. If successfully exploited, this vulnerability could lead to remote code execution. Sometimes, an unsuccessful attack could still lead to denial of service conditions.
Mitigation and Trend Micro Solutions
IIS 6.0 was included with Windows Server 2003; unfortunately, Microsoft isn't supporting and won't be patching the old OS version anymore. To mitigate the risk, disabling the WebDAV service on the vulnerable IIS 6.0 installation is recommended. Newer versions of Windows Server shipped with newer versions of IIS are not affected by this vulnerability.
