A NULL pointer dereference vulnerability has been reported to affect several QNAP operating system versions. If exploited, the vulnerability could allow authenticated administrators to launch a denial-of-service (DoS) attack via a network.
We have already fixed the vulnerability in the following versions: QTS 5.1.2.2533 build 20230926 and later QuTS hero h5.1.2.2534 build 20230927 and later QuTScloud c5.1.5.2651 and later
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
