Cleartext Storage of WiFi Credentials in Zyxel AX7501-B0 Firmware

CVE-2022-45439

Summary

The Zyxel AX7501-B0 firmware prior to version V5.17(ABPC.3)C0 improperly stores WiFi credentials in cleartext within its configuration file. This design flaw allows an unauthenticated attacker to potentially access these credentials, particularly if they are able to exploit another existing vulnerability to retrieve the configuration file. As a result, this opens up the WLAN service to unauthorized access, risking the security of the network.
