Brocade Fabric OS <9.2.2 Remote SSH Key Forgery Enables MITM Session Hijacking
CVE-2024-7516 Published on November 12, 2024
Brocade Fabric OS before 9.2.2 does not enforce strict host key checking
A vulnerability in Brocade Fabric OS versions before 9.2.2 could allow man-in-the-middle attackers to conduct remote Service Session Hijacking that may arise from the attacker's ability to forge an SSH key while the Brocade Fabric OS Switch is performing various remote operations initiated by a switch admin.
Weakness Type
Key Exchange without Entity Authentication
The software performs a key exchange with an actor without verifying the identity of that actor. Performing a key exchange will preserve the integrity of the information sent between two entities, but this will not guarantee that the entities are who they claim they are. This may enable an attacker to impersonate an actor by modifying traffic between the two entities. Typically, this involves a victim client that contacts a malicious server that is impersonating a trusted server. If the client skips authentication or ignores an authentication failure, the malicious server may request authentication information from the user. The malicious server can then use this authentication information to log in to the trusted server using the victim's credentials, sniff traffic between the victim and trusted server, etc.
