CVE-2023-47222Network attack vector

Network-exposed sensitive information disclosure

Published Apr 26, 2024 · Updated Aug 2, 2024

Sensitive information exposure in QNAP Media Streaming Add-on 500.1.x allows remote attackers to compromise a NAS via a network. QNAP maps the flaw to path traversal and improper authentication but has not disclosed the affected endpoint, pathname handling, or information exposed. Exploitation requires user interaction but no prior privileges, and the vendor rates confidentiality, integrity, and availability impact as high.
