VULN-DEV, how-do-you-do!

       I received a response from IMATIX after forwarding the posts from
       VULN-DEV re remotely crashing Xitami webserver by sending simple GET
       command. They immediately released 2.4d7 with fix. Also, they have
       said that they will now change default install behaviour of Xitami to
       not allow anon FTP logins.

Anyone can remotely crash Xitami webserver by sending simple GET
command. On remote side will be:

Assertion Failed!
Module: D:\Imatix\Develop\Smt\Smthttpl.c , line 745

All you need to do is just telnet to remote computer and execute
GET<space><enter><enter> command. Also Xitami will crash if you'll execute
POST<space><enter><enter> or HEAD<space><enter><enter> command.


There is another DoS in Xitami. By default installation Xitami
allows anonymous users on ftp. So connect to remote computer as
anonymous user and execute cd con/con command.

Tried to bring it down from a remote account which failed, got std http
error msg back.
Version Xitami 2.4d1 on Winx, set up for this one on http 8080, without
authorisation or ipmasks.

Are you sure it ain't because you used a beta version?
Or did you test some previous versions as well?
Is it in the console or the std. version?
Did you compile it yourself or did you get a precompiled version?


Questions, questions...

Cheers, Mitch.
