Description

In affected TP-Link Aginet devices, use of hardcoded cryptographic keys embedded in the firmware to protect sensitive configuration data may allow an attacker who has access to device storage to recover the keys and decrypt stored data. Successful exploitation may allow access to decrypted sensitive configuration data, including credentials and service-related information.
