How CVE-2025-2656 Works
The vulnerability exists in `/admin/login.php` due to improper sanitization of the `Username` parameter. Attackers can inject malicious SQL queries through this input field, bypassing authentication and executing arbitrary database commands. The system fails to validate user-supplied data before concatenating it into SQL statements, enabling classic SQL injection. Remote exploitation is possible without authentication, allowing unauthorized access, data theft, or system compromise. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N) confirms network-based attacks with low complexity.
