CVE-2017-9856 (GCVE-0-2017-9856)

Vulnerability from cvelistv5 – Published: 2017-08-05 17:00 – Updated: 2024-08-05 17:18 Disputed

Summary

An issue was discovered in SMA Solar Technology products. Sniffed passwords from SMAdata2+ communication can be decrypted very easily. The passwords are "encrypted" using a very simple encryption algorithm. This enables an attacker to find the plaintext passwords and authenticate to the device. NOTE: the vendor reports that only Sunny Boy TLST-21 and TL-21 and Sunny Tripower TL-10 and TL-30 could potentially be affected

Severity ?
