## Technical details

A SQL injection vulnerability exists in /fos/admin/ajax.php?action=save_user where the 'username' parameter is passed directly into SQL queries without proper input validation or parameterization. The vulnerability is remotely exploitable via POST requests and requires no authentication or user interaction. An attacker can inject malicious SQL payloads (time-based blind or boolean-based blind techniques) through the username field to extract database contents, modify data, or execute arbitrary database operations. Input validation and prepared statements with parameter binding should be implemented to remediate this issue.
