Qnap

Format string vulnerability in QNAP Qsync Central that allows authenticated remote attackers to read sensitive data or modify memory without user interaction. The vulnerability affects all versions prior to Qsync Central 4.5.0.6 (released March 20, 2025), with a CVSS score of 8.1 indicating high severity. While no public exploit or KEV status is currently documented, the low attack complexity and requirement for only low-privilege user access make this a significant risk for organizations running vulnerable versions.

Command injection vulnerability affecting QNAP NAS operating systems (QTS and QuTS hero) that allows authenticated remote attackers to execute arbitrary commands with high severity (CVSS 8.8). The vulnerability requires valid user credentials but no user interaction, making it exploitable by compromised accounts or insider threats. QNAP has released patches as of March 21, 2025, and exploitation details are limited in public disclosures at this time.
