Executive brief
HPE Networking Fabric Composer is a network fabric management platform used by enterprises to configure and oversee their network infrastructure. A privilege escalation vulnerability in its API allows authenticated operators with low-level permissions to perform unauthorized state-changing actions, including modifications to managed systems' configurations. This could enable unauthorized reconfiguration of critical network infrastructure by insider threats or compromised operator accounts.
Technical details
The vulnerability is a privilege escalation flaw in the API of HPE Networking Fabric Composer that fails to properly enforce authorization controls. An authenticated user with low-privilege operator permissions can bypass authorization checks to execute state-changing API operations that should be restricted to higher-privilege roles. The attack requires valid credentials and network access to the affected API. Successful exploitation allows an attacker to modify the configuration of systems managed by the platform, potentially disrupting network operations or enabling lateral movement within managed infrastructure. HPE has released patches for affected versions.
