CVE-2023-45623Network attack vector

Unauthenticated service interruption via PAPI requests

Published Nov 14, 2023 · Updated Aug 30, 2024

Denial of service in affected HPE Aruba Access Points allows remote attackers to interrupt operation through PAPI Wi-Fi Uplink requests. The vendor identifies the Wi-Fi Uplink service as the locus but has not disclosed how it mishandles a crafted PAPI request. No authentication or user interaction is required; affected branch ceilings are ArubaOS 10.4.0.2 and 10.5.0.0 and InstantOS 8.6.0.22, 8.10.0.8, and 8.11.1.2, with interruption limited to the targeted access point.
