An authentication bypass by spoofing vulnerability has been reported to affect several QNAP operating system versions. The remote attackers can then exploit the vulnerability to access resources which are not otherwise accessible without proper authentication.
We have already fixed the vulnerability in the following versions: QTS 5.2.7.3297 build 20251024 and later QuTS hero h5.2.7.3297 build 20251024 and later QuTS hero h5.3.1.3292 build 20251024 and later
Weakness
This attack-focused weakness is caused by incorrectly implemented authentication schemes that are subject to spoofing attacks.
