Traffic interception via weak SSH key exchange
Published May 3, 2023 · Updated Oct 22, 2024
Weak SSH key exchange in affected Fortinet FortiNAC releases allows remote attackers to intercept or alter protected traffic. The SSH service offers a weak key-exchange algorithm, although Fortinet has not disclosed the specific algorithm or its implementation details. Exploitation requires an on-path network position and user interaction; the reported consequence is limited to disclosure or modification of session data.
