## Overview

A vulnerability in Brocade ASCG version before 3.5.0 could allow an attacker to obtain a static cryptographic key hardcoded into the software binaries to secure sensitive data at rest and to protect inter-node communication protocols. An attacker who extracts this key can decrypt stored management credentials or craft forged administrative synchronization messages.

## Affected

- `brocade_active_support_connectivity_gateway < 3.5.0`

## Remediation

Upgrade past the affected range:

- `brocade_active_support_connectivity_gateway 3.5.0`
