Summary

Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1 are affected. The account management interface fails to properly check authorization, due to a partial string comparison (CWE-187). Under specific conditions, an authenticated user with low privileges, reachable over an adjacent network, can change another account's access and assign administrative roles to it.

Description from the CNA

An authentication logic and privilege escalation vulnerability exists in the account management interface of Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1. Under specific conditions, an authenticated user can bypass authorization restrictions intended to prevent modifying another account's access privileges. Exploitation allows a lower-privileged user to assign administrative roles to a target account, leading to localized privilege escalation.
