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","published":"2017-08-05T17:29:01.000Z","lastModified":"2026-06-17T01:29:04.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.0","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-327"],"affected":["sma/sunny boy 3600 firmware","sma/sunny boy 5000 firmware","sma/sunny tripower core1 firmware","sma/sunny tripower 15000tl firmware","sma/sunny tripower 20000tl firmware","sma/sunny tripower 25000tl firmware","sma/sunny tripower 5000tl firmware","sma/sunny tripower 12000tl firmware","sma/sunny tripower 60 firmware","sma/sunny boy 3000tl firmware","sma/sunny boy 3600tl firmware","sma/sunny boy 4000tl firmware","sma/sunny boy 5000tl firmware","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 4.0 firmware","sma/sunny boy 5.0 firmware","sma/sunny central 2200 firmware","sma/sunny central 1000cp xt firmware","sma/sunny central 800cp xt firmware","sma/sunny central 850cp xt firmware","sma/sunny central 900cp xt 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 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 central storage 1000 firmware","sma/sunny central storage 2200 firmware","sma/sunny central storage 2500-ev firmware","sma/sunny boy storage 2.5 firmware"],"epss":{"score":0.01127,"percentile":0.66164,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (1.13%).
