Summary

PHPNuxBill through 2025.3.20 contains an unauthenticated SQL injection flaw in the radius.php FreeRADIUS REST endpoint, which builds whereRaw() queries from request parameters without neutralizing them (CWE-89). A remote attacker sends crafted username, macAddr or nasid values to the accounting or authenticate actions and extracts customer records and credentials through time-based blind SQL injection. The CVSS 4.0 base score is 9.3 (critical). No public exploit is linked in the references, and CISA does not list the flaw in KEV.
