Information disclosure

DISPUTED 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...

CVE-2017-9857

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, etc. can be...

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-2017-9858

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-2017-9864

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 analysis...

CVE-2017-9858

CVE-2017-9858 affects SMA Solar Technology inverters (Sunny Boy TLST-21, TL-21; Sunny Tripower TL-10, TL-30). By sending crafted packets to the inverter and observing responses, an attacker can determine which user accounts are active or inactive, enabling brute-force planning. The vendor notes t...

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-2017-9859

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-2017-9855

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-2017-9853

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 set of...

CVE-2017-9861

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 with the...

CVE-2017-9864

Summary of CVE-2017-9864 (SMA Solar Technology inverter/time setting issue) : An attacker can change the plant time on SMA Solar Technology inverters (notably Sunny Boy TLST-21/TL-21 and Sunny Tripower TL-10/TL-30) without authentication, causing the system time to shift. This can affect timestam...

CVE-2017-9859

CVE-2017-9859 concerns SMA Solar Technology inverters (Sunny Boy TLST-21/TL-21 and Sunny Tripower TL-10/TL-30). The issue is use of a weak hashing algorithm to encrypt passwords for REGISTER requests, which can be cracked offline, enabling an attacker to recover the password and register at SMA s...

CVE-2017-9863

SMA Solar Technology Sunny Explorer-related CSRF vulnerability (CVE-2017-9863) affects Sunny Boy TLST-21/TL-21 and Sunny Tripower TL-10/TL-30. When a user runs Sunny Explorer and visits a malicious host, an unauthenticated attacker can exploit cross-site request forgery to change inverter setting...

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-2017-9854

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-2017-9855

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

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-2017-9855

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...
