CVE-2022-33178Network attack vector

Privileged code execution via RADIUS role script

Published Oct 25, 2022 · Updated May 7, 2025

Improper input validation in Brocade Fabric OS before 9.0.0 allows remote authenticated users to execute arbitrary code through RADIUS. The RADIUS authentication system executes a script supplied in the Brocade-Auth-Role parameter instead of validating it as role data. Exploitation requires privileged control of the RADIUS-supplied attribute and grants code execution on the switch.
