Administrator-gated memory disclosure and modification via format string
Published Oct 3, 2025 · Updated Oct 3, 2025
Externally controlled format strings in QNAP QTS 5.2.x and QuTS hero h5.2.x allow remote authenticated users to read secrets or modify memory. QNAP has not disclosed the affected component or function, beyond identifying that attacker-controlled input is used as a format string. Exploitation requires an administrator account; successful attacks expose secret data or change process memory contents.
