Proxy credential disclosure via diagnostic bundle storage

Published Oct 8, 2026 · Updated Oct 8, 2026

Information disclosure in SupportLink on Brocade Fabric OS before 10.0.1 allows attackers to read HTTP proxy credentials from support bundles. Its diagnostic collection utilities store the full authenticated proxy URL in cleartext rather than excluding the credentials. Exposure requires SupportLink to use an authenticated HTTP proxy and access to a diagnostic bundle, including a copy held by support personnel or on a file share.
