Secret disclosure and memory modification via format strings
Published Oct 3, 2025 · Updated Oct 3, 2025
Format-string injection in QTS 5.2.x and QuTS hero h5.2.x allows remote authenticated users to read secret data or modify memory. QNAP has not disclosed the affected component, input field, or formatting call that interprets attacker-controlled text. Administrator access is required, and the published record limits the established consequences to secret-data exposure or process-memory modification.
