This week several vulnerabilities were reported in EVlink charging stations manufactured by Schneider Electric, that service electric vehicles. EVlink provides electric vehicle charging products for both home and commercial use, placing these vulnerabilities in the subset category of equipment manufacturing of the Manufacturing Sector of the Critical Infrastructure Sectors designated by the Presidential Policy Directive 21 . The three vulnerabilities (CVE ID: CVE-2018-7800, CVE-2018-7801, and CVE-2018-7802) can grant a malicious actor elevated privileges to the charging interface allowing them to have the highest control over the charging station. The most critically rated vulnerability CVE-2018-7800 can allow an individual to gain access to the charging interface, and execute various commands that allow actions ranging from unlocking the charging cable resulting in theft of the device to altering the charging process of a consumer. The two other vulnerabilities CVE-2018-7801 and CVE-2018-7802 grant similar privileges through different methods. CVE-2018-7801 grants elevated privileges when a remote code execution is performed, and CVE-2018-7802 is a SQL injection vulnerability allowing elevated privileges to the web interface of the product.
