Default credentials

DISPUTED An issue was discovered in SMA Solar Technology products. All inverters have a very weak password policy for the user and installer password. No complexity requirements or length requirements are set. Also, strong passwords are impossible due to a maximum of 12 characters and a limited s...

Design/Logic Flaw

DISPUTED 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...

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-2017-9860

An issue was discovered in SMA Solar Technology products. An attacker can use Sunny Explorer or the SMAdata2+ network protocol to update the device firmware without ever having to authenticate. If an attacker is able to create a custom firmware version that is accepted by the inverter, the invert...

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-2017-9862

An issue was discovered in SMA Solar Technology products. When signed into Sunny Explorer with a wrong password, it is possible to create a debug report, disclosing information regarding the application and allowing the attacker to create and save a .txt file with contents to his liking. An...

Default credentials

DISPUTED An issue was discovered in SMA Solar Technology products. 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 cracker...

Authentication flaw

DISPUTED An issue was discovered in SMA Solar Technology products. The SIP implementation does not properly use authentication with encryption: it is vulnerable to replay attacks, packet injection attacks, and man in the middle attacks. An attacker is able to successfully use SIP to communicate...

Cross site request forgery (csrf)

DISPUTED An issue was discovered in SMA Solar Technology products. If a user simultaneously has Sunny Explorer running and visits a malicious host, cross-site request forgery can be used to change settings in the inverters for example, issuing a POST request to change the user password. All Sunny...

CVE-2017-9863

An issue was discovered in SMA Solar Technology products. If a user simultaneously has Sunny Explorer running and visits a malicious host, cross-site request forgery can be used to change settings in the inverters for example, issuing a POST request to change the user password. All Sunny Explorer...

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...

Design/Logic Flaw

DISPUTED An issue was discovered in SMA Solar Technology products. An attacker can change the plant time even when not authenticated in any way. This changes the system time, possibly affecting lockout policies and random-number generators based on timestamps, and makes timestamps for data analys...

Authentication flaw

DISPUTED An issue was discovered in SMA Solar Technology products. The SMAdata2+ communication protocol does not properly use authentication with encryption: it is vulnerable to man in the middle, packet injection, and replay attacks. Any setting change, authentication packet, scouting packet, et...

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-2017-9859

An issue was discovered in SMA Solar Technology products. 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...

CVE-2017-9852

An Incorrect Password Management issue was discovered in SMA Solar Technology products. Default passwords exist that are rarely changed. User passwords will almost always be default. Installer passwords are expected to be default or similar across installations installed by the same company but a...
