CVE-2022-28169Network attack vector

Admin escalation via operator session reuse

Published Oct 25, 2022 · Updated May 9, 2025

Privilege escalation in Brocade Fabric OS before 9.1.1, 9.0.1e, or 8.2.3c allows remote authenticated users to create admin users via Webtools. The Webtools user-addition request accepts an intercepted operator authorization header, allowing a low-privilege role to reuse that session identity and assign administrator privileges. The attacker must already authenticate to the management interface and obtain the operator header; the impact is unauthorized account creation and full confidentiality and integrity loss on the switch.
