CVSS v3 9.8
ATTENTION: Exploitable remotely/low skill level to exploit
**Vendor:**Schneider Electric
Equipment: EVLink Parking
Vulnerabilities: Use of Hard-coded Credentials, Code Injection, SQL Injection
Successful exploitation of these vulnerabilities could allow an attacker to stop the device and prevent charging, execute arbitrary commands, and access the web interface with full privileges.
The following versions of EVLink Parking, an electric vehicle charging station, are affected:
A hard-coded credentials vulnerability exists that could enable an attacker to gain access to the device.
CVE-2018-7800 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
A code injection vulnerability exists that could allow remote code execution with maximum privileges.
CVE-2018-7801 has been assigned to this vulnerability. A CVSS v3 base score of 8.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).
A SQL injection vulnerability exists that could give an attacker access to the web interface with full privileges.
CVE-2018-7802 has been assigned to this vulnerability. A CVSS v3 base score of 6.4 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N).
Vladimir Kononovich and Vyacheslav Moskvin of Positive Technologies reported these vulnerabilities to Schneider Electric.
Schneider Electric recommends users setup a firewall to restrict remote access to the charging stations by unauthorized users. A software update is also available for download to mitigate these vulnerabilities:
