Si se explota, la vulnerabilidad podría permitir a los usuarios comprometer la seguridad del sistema a través de una red. El fabricante ha solucionado la vulnerabilidad en las siguientes versiones: QTS 5.1.3.2578 compilación 20231110 y posteriores QTS 4.5.4.2627 compilación 20231225 y posteriores QuTS hero h5.1.3.2578 compilación 20231110 y posteriores QuTS hero h4.5.4.2626 compilación 20231225 y posteriores QuTScloud c5.1.5.2651 y posteriores

This vulnerability allows remote attackers to make arbitrary changes to configuration on affected installations of QNAP TS-464 NAS devices. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the privWizard API endpoints. The issue results from the lack of proper validation of a user-supplied string before using it to update configuration. An attacker can leverage this vulnerability to change the configuration of the system.
