No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

Cleartext storage and exposure of WPA2 credentials, and missing authentication on the rr/wr memory read/write commands, in the unauthenticated UART debug console of the Tenda N300 F3 (V603) allow a physically proximate attacker to obtain stored WPA2 credentials in cleartext and to read or write arbitrary memory via the serial console.
