Description
An issue was discovered in SMA Solar Technology products. By sending crafted packets to an inverter and observing the response, active and inactive user accounts can be determined. This aids in further attacks (such as a brute force attack) as one now knows exactly which users exist and which do not. NOTE: the vendor's position is that this "is not a security gap per se." Also, only Sunny Boy TLST-21 and TL-21 and Sunny Tripower TL-10 and TL-30 could potentially be affected
