CVE-2025-59392

Admin account takeover via unauthenticated USB reset

Published Nov 6, 2025 · Updated Nov 6, 2025

Authentication bypass in Elspec G5 devices through 1.2.2.19 allows physically proximate attackers to reset the Admin password via USB. The device processes a publicly documented reset string from an inserted USB drive as an alternate password-reset channel without authenticating the person at the port. Physical access to a USB port is required, and a successful reset grants control of the administrative account.
