Name of the Vulnerable Software and Affected Versions Brocade Fabric OS versions 8.1.0 through 9.0.0

Description The issue is related to a weakness in the ldap implementation in Brocade Fabric OS, configured in Virtual Fabric mode. This weakness could allow a remote ldap user to login to the Brocade Fibre Channel SAN switch with "user" privileges if it is not associated with any groups.

Recommendations For Brocade Fabric OS versions 8.1.0 through 9.0.0, consider updating to version 9.0.0 or later to resolve the issue. As a temporary workaround, consider restricting access to the ldap implementation until a patch is available. Additionally, ensure that all ldap users are properly associated with groups to minimize the risk of exploitation.
