Technical details
The vulnerability is an information disclosure issue in the web-based management interface of HPE Networking Fabric Composer that allows unauthenticated remote access to sensitive data. An attacker on the network can reach the web interface and extract cleartext information without authentication, potentially gaining access to credentials, configuration data, or other sensitive information handled by the management interface. This exposed data could be leveraged to compromise additional network infrastructure components. Patch availability should be confirmed with HPE security advisories.
