Cryptographic compromise via weak random values
Published Jun 9, 2022 · Updated Aug 3, 2024
Cryptographic weakness in ZTE MF297D firmware MF297D_Nordic1_B05 allows attackers to compromise device security via adjacent access. The firmware uses weak random values in an undisclosed cryptographic operation; ZTE has not identified the affected component or protected value. High privileges on an adjacent network are required, and the vendor reports confidentiality, integrity, and availability effects without specifying the resulting actions.
