Detailsinfo

A vulnerability was found in SMA Solar Technology Solar System and PV System (affected version unknown). It has been declared as problematic. Affected by this vulnerability is an unknown functionality of the component SIP. The manipulation with an unknown input leads to a injection vulnerability. The CWE definition for the vulnerability is CWE-74. The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. As an impact it is known to affect confidentiality. The summary by CVE is:

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 device from anywhere within the LAN. An attacker may use this to crash the device, stop it from communicating with the SMA servers, exploit known SIP vulnerabilities, or find sensitive information from the SIP communications. Furthermore, because the SIP communication channel is unencrypted, an attacker capable of understanding the protocol can eavesdrop on communications. For example, passwords can be extracted.

The bug was discovered 06/24/2017. The weakness was published 08/05/2017 (Website). It is possible to read the advisory at sma.de. This vulnerability is known as CVE-2017-9861 since 06/24/2017. The attack can be launched remotely. The exploitation doesn't need any form of authentication. The technical details are unknown and an exploit is not publicly available. The attack technique deployed by this issue is T1055 according to MITRE ATT&CK.

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.
