Name of the Vulnerable Software and Affected Versions
Brocade ASCG versions prior to 3.5.0
Description
An unauthenticated remote attacker can modify the TLS client trust store by supplying an unauthorized Certificate Authority (CA) certificate to an unauthenticated management interface. This allows the system to trust unauthorized certificates, which may enable Man-in-the-Middle (MITM) attacks—a technique where an attacker intercepts and potentially alters communication between two parties—against outbound communications with managed switches and peer nodes.
Recommendations
Update Brocade ASCG to version 3.5.0 or later.
Fix
Improper Certificate Validation
