Title
Authenticated Local Sensitive Information Disclosure in HPE Networking Instant On
Summary
A sensitive information disclosure vulnerability exists in the underlying operating system of HPE Networking Instant On. Successful exploitation could allow an authenticated local attacker with high privileges to retrieve information which could be used to potentially gain further access to network services supported by HPE Networking Instant On, only if certain preconditions outside of the attacker's control are met.
