Many Security Holes in the Microsoft Frontpage extensions

In recent days we noticed that many people suffering for hacking activities with their site, and they migrate on CentrioHost only to prevent their site from being hacked. We already post some article for them how to prevent site hacking. We just recently noticed that web-hosts offering FrontPage Extensions on their site also get hacked now-a-days :( Here we explain about this issues....
 
 
First of all, Frontpage is brain damaged (just have to set the stage).

Ok, Frontpage works like this when you want to publish files:

It tries to GET "http://www.yourdomain.com/_vti_inf.html".  This file contains the version of the FP extensions and the path on the server where the extensions are located. When you use Frontpage to upload content, it will try and fetch this file, if it can, it then tries to POST to :
"http://www.yourdomain.com/_vti_bin/shtml.exe/_vti_rpc" (that's the default).

This server binary is not password protected, so it is able to post a query to it.  The first thing it does is just establish a protocol rev in which the client and server are going to talk, and what functions the server provides.

If you have any people using Frontpage, it's likely that they FTPed the _vti_inf.html from their home machine up to your site.  Then they tried to publish, and it tried HTTP first.  If HTTP fails, it just kicks over to FTP as the publishing protocol (and notifies the user that they can't use WebBots and stuff).

Incidentally, I have a passion to hate the FP extensions.  They are fundamentally stupid in nearly all respects of implementation.

Firsly, they maintain a crapload of meta files (one shadow for every file managed) then they have all of their config info in a bunch of text files in the _vti_pvt directory.  (Oh, BTW, there exists a very HUGE privacy hole in the FP extenstions).  If you go to a site that has FP extensions, just pick any directory in the URL, yank the filename off, and put "_vti_cnf" there instead...you'll get a complete listing of all the files in the real directory.  With this you can snatch files that weren't meant to be seen by the public...and it's available on ALL FP enabled sites.

Hmm, I've contributed a "privacy bug" now. :)

Want to know an even cooler hack?  Want to break into Frontpage enabled sites?

Just snarf the "administrators.pwd" and "authors.pwd" file in:

"http://www.yourdomain.com/_vti_pvt/administrators.pwd"

That'll net you the password file for the web.  Just convert it properly and run Crack on it to obtain a useful password for defacing web sites!

Want even more???

Frontpage 98 fucks up the permissions so bad that it makes the _vti_pvt directory WORLD WRITABLE!!! No shit, you can do whatever you want to stuff in that directory.

Hmm, I love incompetent nitwits that think they can buy someone elses crappy Unix shit and sell it as their own!!! :)

Oh, you know why all the directories begin with "VTI"???

"Vermeer Technology Inc". The people the M$ bought for Frontpage. :)
____________________________

Never Use FrontPage Extensions, your site can be easily hacked then !! We dont offer this Extensions, however if you migrate your site from other server, these files will be come to your new site from other host. Also if you upload with FrontPage software, its also makes these directory on your public_html folder and hackers can easily hack your site - Security Dept, CentrioHost.com
