CVE-2025-29882
Estado: AnalizadaMedia (5.3)—
A NULL pointer dereference vulnerability has been reported to affect several QNAP operating system versions. If a remote attacker gains a user account, they can then exploit the vulnerability to launch a denial-of-service (DoS) attack.
We have already fixed the vulnerability in the following versions: QTS 5.2.5.3145 build 20250526 and later QuTS hero h5.2.5.3138 build 20250519 and later
