Vulnerability Details : CVE-2017-9863
An issue was discovered in SMA Solar Technology products. If a user simultaneously has Sunny Explorer running and visits a malicious host, cross-site request forgery can be used to change settings in the inverters (for example, issuing a POST request to change the user password). All Sunny Explorer settings available to the authenticated user are also available to the attacker. (In some cases, this also includes changing settings that the user has no access to.) This may result in complete compromise of the device. NOTE: the vendor reports that exploitation is unlikely because Sunny Explorer is used only rarely. Also, only Sunny Boy TLST-21 and TL-21 and Sunny Tripower TL-10 and TL-30 could potentially be affected
