CVE-2017-9854
CriticalSummary
An issue was discovered in SMA Solar Technology products that allows plaintext passwords to be sniffed as they are typed into Sunny Explorer by the user. These passwords can then be used to compromise the device.
Risk Assessment
The risk to the organization involves the potential for unauthorized control over the device, although the likelihood of exploitation is low since packets are typically sent only once during installation.
Recommendation
It is recommended to monitor and secure local connections and restrict access to the Sunny Explorer application to minimize the risk of password interception.
Other vulnerabilities in SMA Solar Technology products, specifically Sunny Boy TLST-21, TL-21, Sunny Tripower TL-10, and TL-30
See all- CVE-2017-9861Critical
An issue was discovered in SMA Solar Technology products related to the SIP implementation, which does not properly use authentication with encryption. This makes it vulnerable to replay attacks, packet injection attacks, and man in the middle attacks.
- CVE-2017-9860Critical
An issue was discovered in SMA Solar Technology products that allows an attacker to update device firmware without authentication using the SMAdata2+ protocol or Sunny Explorer. If an attacker creates a custom firmware version accepted by the inverter, it can be completely compromised.
Original NVD description (English source)
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 exploitation likelihood is low because these packets are usually sent only once during installation. Also, only Sunny Boy TLST-21 and TL-21 and Sunny Tripower TL-10 and TL-30 could potentially be affected
