CVE-2023-23363 & CVE-2023-23364: High-Severity Bugs Unveiled in QNAP’s QTS & Multimedia Console
In the era of cloud computing and digitized storage, keeping systems secured is paramount. But as technology advances, so do the tactics of cybercriminals. QNAP has released security updates to patch two critical vulnerabilities in its QTS operating system and Multimedia Console application. Both vulnerabilities could allow attackers to execute arbitrary code on affected devices, giving them complete control over the system.
