Summary

An issue was discovered in SMA Solar Technology products that allows for cross-site request forgery when a user runs Sunny Explorer and visits a malicious host. An attacker can change inverter settings, including user passwords.

Risk Assessment

This may result in complete compromise of the device, posing a serious security threat to the system. However, the vendor reports that exploitation is unlikely due to the rare use of Sunny Explorer.

Recommendation

It is recommended to restrict access to the Sunny Explorer application and monitor user activity. Consider updating the software if patches are available.

Original NVD description (English source)

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
