CVE-2017-9863 describes a Cross-Site Request Forgery (CSRF) vulnerability in SMA Solar Technology products, specifically affecting Sunny Boy TLST-21, TL-21, Sunny Tripower TL-10, and TL-30 inverters when Sunny Explorer is running. This vulnerability allows an attacker to manipulate inverter settings, including changing user passwords, potentially leading to complete device compromise. With a CVSS score of 8.8 (High), the attack requires user interaction (UI:R) but has low attack complexity (AC:L), posing a significant risk of high impact to confidentiality, integrity, and availability. While the vendor considers exploitation unlikely due to infrequent Sunny Explorer usage, there is no public exploit code (Metasploit, Nuclei, ExploitDB) and it is not listed in the KEV catalog, though it has garnered some community discussion and media coverage.
