An improper certificate validation vulnerability has been reported to affect several QNAP operating system versions.
Noroxi assessment
Priority: Monitor (action score 29/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.15% (FIRST EPSS).
- Physical access to the device is required. No account or password is required. No special conditions are required; it is repeatable.
- According to the record, no fixed version is available yet.
Low priority for now. Update when a fix is released; follow the vendor's advisory.

An improper certificate validation vulnerability has been reported to affect several QNAP operating system versions. If exploited, the vulnerability could allow attackers with local network access to compromise the security of the system. We have already fixed the vulnerability in the following versions: QTS 5.1.9.2954 build 20241120 and later QTS 5.2.2.2950 build 20241114 and later QuTS hero h5.1.9.2954 build 20241120 and later QuTS hero h5.2.2.2952 build 20241116 and later

Root cause
A certificate validation error is silently swallowed instead of terminating the connection. Often, code added for a test environment makes its way into production.
