| CVE-2017-9864 | 1 Sma | 78 Sunny Boy 1.5, Sunny Boy 1.5 Firmware, Sunny Boy 2.5 and 75 more | 2019-10-03 | 5.0 MEDIUM | 7.5 HIGH |
| ** 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 analysis unreliable. NOTE: the vendor reports that this is largely irrelevant because it only affects log-entry timestamps, and because the plant time would later be reset via NTP. (It has never been the case that a lockout policy or random-number generator was affected.) Also, only Sunny Boy TLST-21 and TL-21 and Sunny Tripower TL-10 and TL-30 could potentially be affected. | |||||
| CVE-2017-9857 | 1 Sma | 78 Sunny Boy 1.5, Sunny Boy 1.5 Firmware, Sunny Boy 2.5 and 75 more | 2017-08-22 | 4.3 MEDIUM | 8.1 HIGH |
| ** 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, etc. can be replayed, injected, or used for a man in the middle session. All functionalities available in Sunny Explorer can effectively be done from anywhere within the network as long as an attacker gets the packet setup correctly. This includes the authentication process for all (including hidden) access levels and the changing of settings in accordance with the gained access rights. Furthermore, because the SMAdata2+ communication channel is unencrypted, an attacker capable of understanding the protocol can eavesdrop on communications. NOTE: the vendor's position is that authentication with encryption is not required on an isolated subnetwork. Also, only Sunny Boy TLST-21 and TL-21 and Sunny Tripower TL-10 and TL-30 could potentially be affected. | |||||
| CVE-2017-9858 | 1 Sma | 78 Sunny Boy 1.5, Sunny Boy 1.5 Firmware, Sunny Boy 2.5 and 75 more | 2017-08-22 | 5.0 MEDIUM | 7.5 HIGH |
| ** DISPUTED ** 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 not. NOTE: the vendor's position is that this "is not a security gap per se." Also, only Sunny Boy TLST-21 and TL-21 and Sunny Tripower TL-10 and TL-30 could potentially be affected. | |||||
| CVE-2017-9863 | 1 Sma | 79 Sunny Boy 1.5, Sunny Boy 1.5 Firmware, Sunny Boy 2.5 and 76 more | 2017-08-22 | 6.8 MEDIUM | 8.8 HIGH |
| ** 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 Explorer settings available to the authenticated user are also available to the attacker. (In some cases, this also includes changing settings that the user has no access to.) This may result in complete compromise of the device. NOTE: the vendor reports that exploitation is unlikely because Sunny Explorer is used only rarely. Also, only Sunny Boy TLST-21 and TL-21 and Sunny Tripower TL-10 and TL-30 could potentially be affected. | |||||
