Protected-data exposure via weak key exchange
Published Nov 21, 2024 · Updated Nov 21, 2024
Weak key exchange in Brocade SANnav before 2.2.2 allows remote authenticated users to read protected data from network traffic. Services on ports 24, 6514, 18023, 19094, and 19095 negotiate cryptographic key-exchange algorithms that Brocade classifies as weak; the algorithm names and protocol details are undisclosed. Exploitation requires low-privileged access and cryptanalysis of captured traffic, with no reported integrity or availability impact.
