Overview of the QNAP Zero-Days
Several QNAP (Quality Network Appliance Provider) Operating Systems for Network Attached Storage (NAS) zero-day vulnerabilities have been discovered and are now impacting over 80,000 devices. These were discovered as zero-day vulnerabilities and are still unpatched for two of the four affected Operating Systems. QNAP is responsible for providing network-attached storage appliances used for sharing files, storage management and surveillance applications, and virtualization. Basically, QNAP is the spot to back up all of your important files, photos, media, and music, an overall storage hub.
The vulnerabilities can be traced through CVE-2022-27597 and CVE-2022-27598, which are memory access violations that could cause unstable code and provide a patch for an authenticated cybercriminal to execute arbitrary code. If these are exploited, the vulnerability allows remote authenticated users to get secret values.
These vulnerabilities affect the QTS, QuTS hero, QuTScloud, and QVP OS. It appears QNAP has released fixed versions in QTS version 18.104.22.1686 build 20230322 and later, and the QuTS hero version h22.214.171.1248 build 20230324 and later. Unfortunately, both the QuTScloud and QVP OS remain unpatched, but QNAP is working on a fix for these flaws.
If your device is affected, you can secure it by regularly updating your system to the latest version, which is a common best practice used for many appliances and software versions.
