DescriptionCVE.org

A vulnerability exists in the API of HPE Networking Fabric Composer that allows for an attacker with administrative privileges to access sensitive information in a cleartext format. A successful exploit allows an attacker to retrieve sensitive information that was expected to remain protected within the affected system.

AnalysisAI

Cleartext exposure of sensitive information in the HPE Networking Fabric Composer API allows a local attacker holding administrative credentials to retrieve secrets that the system is expected to protect in encrypted form. The vulnerability is constrained to local access with high privileges already obtained, yielding a CVSS 3.1 score of 4.4 (Medium). …
