Description
A firmware update mechanism in the affected charging controller fails to validate the authenticity of firmware packages delivered through the device's management interface. Because cryptographic signatures are not verified, an attacker with the ability to interfere with or impersonate the management channel could cause the device to install an unauthorized firmware package. This condition could allow execution of unauthorized code with high privileges on the device.
