CVE-2021-46247Network attack vector

Encrypted data disclosure via hard-coded key

Published Feb 17, 2022 · Updated Aug 4, 2024

Hard-coded key use in ASUS CMAX6000 1.02.00 allows remote attackers to recover encrypted data from the device over a network. The firmware embeds a fixed cryptographic key, but public sources do not identify the protected data, algorithm, key location, or recovery procedure. No authentication or user interaction is required according to NVD, and the documented consequence is limited to encrypted-data disclosure.
