Technical details
An OS command injection vulnerability (CWE-78) exists in multiple versions of QNAP's QTS and QuTS hero operating systems. The flaw allows a remote attacker with high privileges (administrator account) to bypass security restrictions and execute arbitrary system commands via the network. The vulnerability stems from improper neutralization of special elements used in an OS command. Successful exploitation results in complete compromise of the Confidentiality, Integrity, and Availability of the host system. QNAP has released security updates to address this issue in QTS 5.2.9.3410, QuTS hero h5.2.9.3410, h5.3.4.3500, and h6.0.0.3459.
