The inverters make use of a weak hashing algorithm to encrypt the password for REGISTER requests. This hashing algorithm can be cracked relatively easily. An attacker will likely be able to crack the password using offline crackers. This cracked password can then be used to register at the SMA servers. NOTE: the vendor's position is that \"we consider the probability of the success of such manipulation to be extremely low.\" Also, only Sunny Boy TLST-21 and TL-21 and Sunny Tripower TL-10 and TL-30 could potentially be affected","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-327"],"references":["http://www.sma.de/en/statement-on-cyber-security.html","http://www.sma.de/fileadmin/content/global/specials/documents/cyber-security/Whitepaper-Cyber-Security-AEN1732_07.pdf","https://horusscenario.com/CVE-information/","http://www.sma.de/en/statement-on-cyber-security.html","http://www.sma.de/fileadmin/content/global/specials/documents/cyber-security/Whitepaper-Cyber-Security-AEN1732_07.pdf"],"products":["sma:sunny_boy_1.5_firmware","sma:sunny_boy_2.5_firmware","sma:sunny_boy_3.0_firmware","sma:sunny_boy_3.6_firmware","sma:sunny_boy_3000tl_firmware","sma:sunny_boy_3600_firmware","sma:sunny_boy_3600tl_firmware","sma:sunny_boy_4.0_firmware","sma:sunny_boy_4000tl_firmware","sma:sunny_boy_5.0_firmware","sma:sunny_boy_5000_firmware","sma:sunny_boy_5000tl_firmware","sma:sunny_boy_storage_2.5_firmware","sma:sunny_central_1000cp_xt_firmware","sma:sunny_central_2200_firmware","sma:sunny_central_500cp_xt_firmware","sma:sunny_central_630cp_xt_firmware","sma:sunny_central_720cp_xt_firmware","sma:sunny_central_760cp_xt_firmware","sma:sunny_central_800cp_xt_firmware","sma:sunny_central_850cp_xt_firmware","sma:sunny_central_900cp_xt_firmware","sma:sunny_central_storage_1000_firmware","sma:sunny_central_storage_2200_firmware","sma:sunny_central_storage_2500-ev_firmware","sma:sunny_central_storage_500_firmware","sma:sunny_central_storage_630_firmware","sma:sunny_central_storage_720_firmware","sma:sunny_central_storage_760_firmware","sma:sunny_central_storage_800_firmware","sma:sunny_central_storage_850_firmware","sma:sunny_central_storage_900_firmware","sma:sunny_tripower_12000tl_firmware","sma:sunny_tripower_15000tl_firmware","sma:sunny_tripower_20000tl_firmware","sma:sunny_tripower_25000tl_firmware","sma:sunny_tripower_5000tl_firmware","sma:sunny_tripower_60_firmware","sma:sunny_tripower_core1_firmware"],"source":"nvd","synced_at":"2026-10-19T20:44:47.710380879+00:00"},"epss":{"cve":"CVE-2017-9859","score":0.01127,"percentile":0.66344,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
