A hard-coded cryptographic key vulnerability exists in the user-configuration backup mechanism of TP-Link RE305 V3 and Archer C7 V5. A fixed AES-128 key and initialization vector are embedded in the firmware configuration-management component.

Successful exploitation may disclose sensitive configuration information contained in a backup file, including administrator passwords and Wi-Fi credentials.
