CVE-2021-41005Network attack vector

Authenticated switch reboot via undisclosed mechanism

Published Apr 12, 2022 · Updated Aug 4, 2024

Denial of service in Aruba Instant On 1930 firmware 1.0.7.0 and earlier allows remote authenticated users to reboot locally managed switches. Aruba has not disclosed the affected web-interface component or the operation on crafted authenticated input that triggers the reboot. Exploitation requires authenticated access to the local web interface; cloud-managed switches are unaffected, and the reported consequence is a service interruption caused by reboot.
