Authenticated code execution via unchecked buffer copy
Published Oct 13, 2023 · Updated Sep 16, 2024
A buffer copy vulnerability in QNAP QTS, QuTS hero, and QuTScloud allows remote authenticated users to execute code via network requests. The advisory identifies a buffer copy that fails to check input size, but does not name the affected function or request field. Authenticated administrator access is required, and successful exploitation can execute attacker-controlled code on the NAS operating system.
