CVE-2024-54127

Wi-Fi credential disclosure via unprotected UART shell

Published Dec 5, 2024 · Updated Dec 5, 2024

Cleartext credential storage in TP-Link Archer C50 before Archer C50(EU)V4 240917 allows physically proximate attackers to read Wi-Fi credentials. The device exposes an access-uncontrolled terminal on its serial interface, and the resulting UART shell makes stored Wi-Fi credentials readable in cleartext. Exploitation requires physical access to the router and discloses its wireless-network credentials.
