CVE-2023-23368 & CVE-2023-23369: Critical Command Injection Vulnerabilities in QNAP Products

Share :

On November 4, 2023, QNAP published security advisories for two critical command injection vulnerabilities impacting multiple versions of QNAP operating systems and applications related to the vendor’s network-attached storage (NAS) devices. Both vulnerabilities have been given critical CVSS scores (CVE-2023-23368: 9.8, CVE-2023-23369: 9.0) and both can lead to unauthenticated, remote threat actors executing commands if successfully exploited.  

At this time, Arctic Wolf has not identified any reports of active exploitation or publicly available proof of concepts. Historically, threat actors have targeted QNAP NAS products with multiple vulnerabilities being added to CISA’s Known Exploited Vulnerabilities Catalog after threat actors leveraged them to deploy ransomware.
