Title
Improper PAPI Packet handling leads to unauthorized access in HPE Networking Instant ON APs
Summary
An authentication bypass vulnerability exists in the PAPI protocol of HPE Networking Instant ON APs that could allow an unauthenticated adjacent attacker to circumvent existing authentication controls. Successful exploitation could allow an attacker to circumvent certain existing authentication mechanisms and send unauthorized network traffic to the target device.
