Technical details
The vulnerability is a privilege escalation flaw in the API of HPE Networking Fabric Composer that fails to properly enforce authorization controls for certain operations. An authenticated user with low-privilege operator role can access information and perform actions beyond their authorized privilege level. The attack requires valid authentication credentials; no unauthenticated network attack is possible. Successful exploitation allows an attacker to retrieve restricted information and make limited unauthorized changes. HPE has released a security update to address this issue.
