Improper privilege assignment in HPE Aruba Networking Fabric Composer 7.0.0 through 7.3.3 allows remote attackers to gain administrative access. The authentication-processing logic accepts specially crafted authentication attributes influenced by an unauthenticated requester and assigns incorrect privileges. Exploitation requires control over authentication responses and results in complete compromise of the Fabric Composer host.
