Sensitive information disclosure via unrestricted storage
Published Jun 16, 2021 · Updated Sep 17, 2024
Insecure storage in QNAP myQNAPcloud Link before 2.2.21 allows remote attackers to read sensitive information from unrestricted storage. QNAP identifies an unrestricted storage mechanism but has not published the storage location, exposed data, or access operation. The vendor describes remote exploitation, while its CVSS assessment requires a local, highly privileged attacker; the consequence is confidentiality-only disclosure.
