CVE-2024-28326

Physical root terminal access

Published Apr 26, 2024 · Updated Jul 9, 2026

Incorrect physical access control in ASUS RT-N12+ B1 firmware allows physically proximate attackers to obtain root terminal access. The public record identifies the router's UART interface as the locus but does not disclose how the console fails to restrict privileged access. Physical access to the router and a UART connection are required; successful access grants full administrative control over the device.
