DescriptionCVE.org

A vulnerability in the web-based management interface of HPE Networking Fabric Composer could allow an unauthenticated remote attacker to access sensitive information if the attacker can convince an authenticated user of the interface to interact with a specially crafted URL. Successful exploitation could allow an attacker to retrieve information which could be used to potentially gain further access to network services supported by HPE Networking Fabric Composer.

AnalysisAI

Sensitive information disclosure in HPE Networking Fabric Composer's web management interface allows an unauthenticated remote attacker to retrieve network service credentials or configuration data by social-engineering an authenticated administrator into clicking a specially crafted URL. The CVSS scope change (S:C) combined with high confidentiality impact (C:H) indicates that the exfiltrated data can reach beyond the web application itself - potentially exposing credentials or configuration for the fabric services that Fabric Composer orchestrates. …
