Lifecycle Timeline
2DescriptionCVE.org
A privilege escalation vulnerability exists in the API of HPE Networking Fabric Composer. Successful exploitation could allow an authenticated low privilege operator user to escalate their permissions to those of an administrative user, leading to complete system compromise.
AnalysisAI
Privilege escalation in HPE Networking Fabric Composer's API allows an authenticated low-privilege operator user to elevate permissions to administrative level, resulting in complete system compromise. The flaw is exploitable over the network without user interaction, making it accessible to any attacker holding a valid operator account. …
