CVE-2017-9855

An issue was discovered in SMA Solar Technology products. A secondary authentication system is available for Installers called the Grid Guard system. This system uses predictable codes, and a single Grid Guard code can be used on any SMA inverter. Any such code, when combined with the installer...

CVE-2017-9854

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...

CVE-2017-9851

An issue was discovered in SMA Solar Technology products. By sending nonsense data or setting up a TELNET session to the database port of Sunny Explorer, the application can be crashed. NOTE: the vendor reports that the maximum possible damage is a communication failure. Also, only Sunny Boy...

CVE-2017-9855

The CVE-2017-9855 issue affects SMA Solar Technology inverters (Sunny Boy TLST-21/TL-21 and Sunny Tripower TL-10/TL-30). The vulnerability arises from the Grid Guard secondary authentication system, which uses predictable codes that can be reused across any SMA inverter. When combined with the in...

CVE-2017-9858

An issue was discovered in SMA Solar Technology products. By sending crafted packets to an inverter and observing the response, active and inactive user accounts can be determined. This aids in further attacks such as a brute force attack as one now knows exactly which users exist and which do no...

CVE-2017-9854

CVE-2017-9854 affects SMA Solar Technology Sunny Explorer-related components. The issue allows an attacker to sniff specific localhost packets and read plaintext passwords as users type them into Sunny Explorer, potentially compromising the entire device. Affected products are Sunny Boy TLST-21/T...

CVE-2017-9856

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...

CVE-2017-9857

The vulnerability CVE-2017-9857 in SMA Solar Technology products stems from the SMAdata2+ protocol: it does not properly use authentication with encryption, making it vulnerable to man-in-the-middle, packet injection, and replay attacks. Affected are Sunny Boy TLST-21/TL-21 and Sunny Tripower TL-...

CVE-2017-9856

The connected PT-2017-19222 entry confirms concrete technical details: SMA Solar Technology inverters (Sunny Boy TLST-21/TL-21 and Sunny Tripower TL-10/TL-30) use a simple encryption algorithm for SMAdata2+ passwords, allowing an attacker to decrypt passwords to plaintext and authenticate to the ...
