CVE-2023-32974Network attack vector

Unauthenticated file disclosure via path traversal

Published Oct 13, 2023 · Updated Sep 17, 2024

Path traversal in QNAP QTS 5.1.x, QuTS hero h5.1.x, and QuTScloud c5.x allows remote attackers to read unexpected files over a network. QNAP has not disclosed the affected component or the operation that fails to constrain an attacker-controlled path. No authentication or user interaction is required, and the documented consequence is limited to exposure of file contents.
