An issue was discovered in SMA Solar Technology products. An attacker can use Sunny Explorer or the SMAdata2+ network protocol to update the device firmware without ever having to authenticate. If an attacker is able to create a custom firmware version that is accepted by the inverter, the inverter is compromised completely. This allows the attacker to do nearly anything: for example, giving access to the local OS, creating a botnet, using the inverters as a stepping stone into companies, etc. NOTE: the vendor reports that this attack has always been blocked by a final integrity and compatibility check. Also, only Sunny Boy TLST-21 and TL-21 and Sunny Tripower TL-10 and TL-30 could potentially be affected

Weakness

When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
