An OS command injection vulnerability has been reported to affect several QNAP operating system versions. If exploited, the vulnerability could allow users to execute commands via a network.
We have already fixed the vulnerability in the following versions:
QTS 5.1.3.2578 build 20231110 and later
QTS 4.5.4.2627 build 20231225 and later
QuTS hero h5.1.3.2578 build 20231110 and later
QuTS hero h4.5.4.2626 build 20231225 and later
QuTScloud c5.1.5.2651 and later
Se ha informado que una vulnerabilidad de inyección de comandos del sistema operativo afecta a varias versiones del sistema operativo QNAP. Si se explota, la vulnerabilidad podría permitir a los usuarios ejecutar comandos a través de una red. Ya hemos 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 execute arbitrary code on affected installations of QNAP TS-464 NAS devices. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed.
The specific flaw exists within the handling of the username parameter. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of admin.
