CVE-2026-85422

Credential disclosure and message forgery via hardcoded key

Published Oct 8, 2026 · Updated Oct 8, 2026

Hardcoded-key use in Brocade Active Support Connectivity Gateway before 3.5.0 allows local users to decrypt stored management credentials. The software binaries embed a static key used both for sensitive data at rest and inter-node protocols, allowing extracted key material to authenticate forged administrative synchronization messages. The published assessment requires high local privileges; exploitation depends on extracting the key and accessing protected data or synchronization traffic.
