A buffer copy without checking size of input vulnerability has been reported to affect several QNAP operating system versions. If exploited, the vulnerability could allow remote attackers who have gained administrator access to execute code. We have already fixed the vulnerability in the following versions: QTS 5.2.1.2930 build 20241025 and later QuTS hero h5.2.1.2929 build 20241025 and later
Solution:
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
