CVE-2026-1407Public exploit

Credential disclosure via cleartext UART boot logs

Published Jan 25, 2026 · Updated Jan 25, 2026

Information disclosure in Beetel 777VR1 Firmware 01.00.09 and 01.00.09_55 allows physically proximate attackers to read credentials. The UART console prints sensitive credentials in cleartext while the router boots, exposing them through an attached serial connection. Exploitation requires physical device access and high-complexity UART interaction; the published impact is limited to disclosure.
