Technical description

Brocade Fabric OS versions before 10.0.1 contain an authorization logic vulnerability in the AAA (Authentication, Authorization, and Accounting) integration framework allows remote authenticated users to gain root-equivalent chassis access controls. By returning specific, crafted Vendor-Specific Attributes (VSAs) or directory claims from an external identity provider (such as RADIUS, LDAP, TACACS+, or Federated IDP), an account can bypass administrative role restriction checks during session establishment.

Remediation

Check the references section for vendor advisories and patches from broadcom. Update fabric_operating_system to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
