**Name of the Vulnerable Software and Affected Versions** Deye/Revolt/Bosswerk Inverter version MW3 15U 5406 1.47/MW3 15U 5406 1.471 **Description** A vulnerability was found in the Access Point Setting Handler component. The manipulation with the input `12345678` leads to the use of a hard-coded password. It is possible to launch the attack on the physical device. The complexity of an attack is rather high, and the exploitation is known to be difficult. The exploit has been disclosed to the public and may be used. **Recommendations** Upgrade to version MW3 16U 5406 1.53 to address this issue. It is recommended to upgrade the affected component. As a temporary workaround, consider restricting access to the Access Point Setting Handler until the upgrade is applied.
