## Overview

An unauthenticated remote attacker can modify the TLS client trust store in Brocade ASCG versions before 3.5.0. By supplying an unauthorized Certificate Authority (CA) certificate to an unauthenticated management interface, the attacker can cause the system to trust unauthorized certificates, potentially enabling Man-in-the-Middle (MITM) attacks against outbound communications with managed switches and peer nodes.

## Affected

- `brocade_active_support_connectivity_gateway < 3.5.0`

## Remediation

Upgrade past the affected range:

- `brocade_active_support_connectivity_gateway 3.5.0`
