An improper restriction of excessive authentication attempts vulnerability has been reported to affect several QNAP operating system versions. If exploited, the vulnerability could allow local network authenticated administrators to perform an arbitrary number of authentication attempts via unspecified vectors. QuTScloud is not affected.
We have already fixed the vulnerability in the following versions: QTS 5.2.0.2782 build 20240601 and later QuTS hero h5.2.0.2782 build 20240601 and later
The product does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame, making it more susceptible to brute force attacks.

Common protection mechanisms include:
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Consider using libraries with authentication capabilities such as OpenSSL or the ESAPI Authenticator. [REF-45]
