Summary
Brocade Fabric OS versions before 10.0.1 contain an improper privilege management flaw (CWE-269) in the AAA integration framework. A remote authenticated user can return crafted Vendor-Specific Attributes or directory claims from an external identity provider such as RADIUS, LDAP, TACACS+, or Federated IDP to bypass administrative role checks during session establishment. This grants root-equivalent chassis access.

Description from the CNA
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.
