Deeper analysis
A buffer copy without checking size of input vulnerability, also referenced under CWE-120 and CWE-121, affects multiple versions of QNAP QTS and QuTS hero operating systems. The flaw permits unauthenticated network-based attacks that can result in remote code execution, reflected in its CVSS 7.2 score with an attack vector of network, low complexity, and no required privileges or user interaction.
An attacker with network access can supply oversized input to trigger the buffer issue and achieve code execution on the affected device. Successful exploitation could allow partial integrity and availability impacts within the compromised scope.
QNAP has addressed the issue in QTS 5.1.7.2770 build 20240520 and later as well as QuTS hero h5.1.7.2770 build 20240520 and later, with details published in security advisory QSA-24-23. The current EPSS of 0.8116, near its recorded peak of 0.8138, indicates sustained exploitation interest following disclosure.
