Description

The Web CGI Script on ZyXEL LTE4506-M606 V1.00(ABDO.2)C0 devices does not require authentication, which allows remote unauthenticated attackers (via crafted JSON action data to /cgi-bin/gui.cgi) to use all features provided by the router. Examples: change the router password, retrieve the Wi-Fi passphrase, send an SMS message, or modify the IP forwarding to access the internal network.

Affected configurations

• zyxel lte4506-m606 firmware (< v1.00\(abdo.6\)c0) • zyxel lte7460-m608 firmware (< v1.00\(abfr.5\)c0) • zyxel wah7706 firmware (< v1.00\(abbc.11\)c0)
