Detailsinfo

A vulnerability classified as problematic has been found in SMA Solar Technology Solar System and PV System (the affected version unknown). This affects an unknown part of the component Sunny Explorer. The manipulation as part of a POST Request leads to a cross-site request forgery vulnerability. CWE is classifying the issue as CWE-352. The web application does not, or can not, sufficiently verify whether a well-formed, valid, consistent request was intentionally provided by the user who submitted the request. This is going to have an impact on integrity. The summary by CVE is:

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.

The bug was discovered 06/24/2017. The weakness was disclosed 08/05/2017 (Website). The advisory is shared at sma.de. This vulnerability is uniquely identified as CVE-2017-9863 since 06/24/2017. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. It demands that the victim is doing some kind of user interaction. Neither technical details nor an exploit are publicly available.

The vulnerability was handled as a non-public zero-day exploit for at least 42 days. During that time the estimated underground price was around $0-$5k. The real existence of this vulnerability is still doubted at the moment.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
