CVE-2024-42396Network attack vector

Unauthenticated access-point service interruption

Published Aug 6, 2024 · Updated Mar 25, 2025

Denial of service in HPE Aruba Instant allows remote attackers to interrupt affected access points through unauthenticated PAPI traffic. The AP Certificate Management daemon accepts PAPI requests, but HPE has not disclosed the specific malformed input or faulty operation that causes the interruption. Network reachability to the PAPI service is sufficient; the documented impact is limited to disrupting normal AP operation, with no confidentiality or integrity impact.
