Well,
after all it wasn't that hard. Just changed AND ORD(SUBSTR(converge_email,$pos,1)) and it worked  variable length isn't a problem just some few more iterations with null as response.
I hope this helps and tnx again to waraxe |

| LoL I'm feeling like talking to myself but guys how do you deal with big databases ? I mean i noticed it takes a while to get the infos. So any help to improve the speed? Is launching multiple scripts parallel with different start and end Ids a good idea ? |

Yes, of course, this is possible. You can use php Curl "curl_multi_exec()" or multiple instances of same script or multithreaded *nix/win program. But performance gain depends on target webserver and database quality. Too much parallelism can kill database and DoS the website  |

Kaotix, could you please post your modified exploit that includes the emails?
I have multiple computers so I usually run the exploit twice on one computer, and leave them on for a day or two. Took about 30hours to extract 3000 members after I couldn't get the admin hash via cracking. |

Just uncomment the get_hash and get_salt if you need them (+ uncomment addline of cours) First the function gets the length of the email adresse then get it (same with nicknames) cause they have both variables size. Start and end index are given throu cli --> script.php start_index end_index
(output log is start-end.txt). I didn't really do anything just modified it according to my needs. If this helps Enjoy

I like the thought of your PHP Script, and is exactly what I was looking to do next...
...however I am getting some issues. Target URL comes back as valid, but then I get syntax errors;
| Quote: | C:\PHP>php.exe username.php
Curl loading success
Target: http://www.xxx.xxx/forums/
Sql table prefix: ibf_
Testing target URL ...
Target URL seems to be valid
Warning: fopen(directory/-.txt): failed to open stream: No such file or director
y in C:\PHP\username.php on line 704
Warning: fwrite(): supplied argument is not a valid stream resource in C:\PHP\us
ername.php on line 705
Warning: fclose(): supplied argument is not a valid stream resource in C:\PHP\us
ername.php on line 706
Testing ID
Sql error! Wrong prefix?
Exiting ...

Any ideas? |

Look at source:
| Code: |
$id_start = $argv[1];// starting user ID, default value "1" is admin's ID
$id_end = $argv[2];// ending user ID
...
$outfile = 'directory/' . $id_start. "-" . $id_end . '.txt';// Log file
|
This exploit needs two commandline parameters: start ID and end ID
try:
| Code: |
php username.php 1 10

Thank you for the quick response. I edited the PHP script with id start 1 and id end 4. Those are the only two I'm worried about. I did not run the script in the syntax you suggested at first. However I have tried that syntax after you have suggested and still return with the same results.
I tried both
php username.php 1 10
php username.php 1 4 |
