CVE-2023-3263Network attack vector

Unauthenticated state disclosure via alternate-name parsing

Published Aug 14, 2023 · Updated Oct 9, 2024

Authentication bypass in Dataprobe iBoot PDU firmware 1.43.03312023 and earlier allows remote attackers to read relay and power state. The REST API credential parser mishandles special characters in supplied credentials and issues a valid authorization token for an alternate name. No prior authentication or user interaction is required; the reported consequence is limited to disclosure of relay and power-distribution state.
