Vulnerability Description
##########################

Calisto Light, Light Plus and Full contains a flaw that may
allow an attacker to carry out an SQL injection attack. The
issue is due to the script not properly sanitizing user-supplied
input to 'usuario' form field and "txtEmail' param upon submision
to 'login.aspx' and '/admin/loginAdmin.aspx' This may allow an
attacker to inject or manipulate SQL queries in the backend database.

######################
Proof Of Concept
######################

this issue can be used to bypass admin validation or user validation

1- If an attacker writes in 'Usuario' box:

someword'or'1'='1'
and click in login button. wen the aplication post to 'login.aspx'
it shows a nice SQL warning but if write:

someword'or'1'='1'--

it bypass validation. if anyones know a user email, then he can
log as this user :)

2- If an attacker writes in 'usuario' box from admin section:

Admin'or'1'='1'--

And click in login button wen the aplication post to
'/admin/loginAdmin.aspx' it bypass Admin validation. :)
