Technical description

An issue was discovered in SMA Solar Technology products. By sniffing for specific packets on the localhost, plaintext passwords can be obtained as they are typed into Sunny Explorer by the user. These passwords can then be used to compromise the overall device. NOTE: the vendor reports that exploitation likelihood is low because these packets are usually sent only once during installation. Also, only Sunny Boy TLST-21 and TL-21 and Sunny Tripower TL-10 and TL-30 could potentially be affected

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
