CVE-2020-8007
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe pwrstudio web application of EV Charger (in the server in Circontrol Raption through 5.6.2) is vulnerable to OS command injection via three fields of the configuration menu for ntpserver0, ntpserver1, and pingip.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceOS command injection vulnerability in the pwrstudio web application of Circontrol Raption EV chargers (versions through 5.6.2) allows remote attackers to execute arbitrary operating system commands by injecting malicious payloads into three configuration fields: ntpserver0, ntpserver1, and pingip. This critical flaw provides complete system compromise with no authentication required.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify pwrstudio web interface accessibilityAttempt to access the pwrstudio web application on the EV charger by navigating to the device IP address on common HTTP/HTTPS ports (80, 443, 8080). Confirm the login page or dashboard loads.Affected if The pwrstudio web interface is accessible from an untrusted network without authentication.
-
Locate firmware version informationLog into pwrstudio and navigate to the system information, about, or device status page. Look for a version field displaying the firmware version number.Affected if The displayed firmware version is 5.6.2 or lower.
-
Identify NTP server configuration fieldsWithin pwrstudio, locate the network settings or time configuration section. Look for input fields labeled ntpserver0 and ntpserver1 where NTP server addresses can be configured.Affected if The ntpserver0 and ntpserver1 configuration fields are present and accessible without authentication.
-
Identify ping configuration fieldIn pwrstudio, locate the diagnostic, network test, or connectivity settings section. Look for a field labeled pingip or similar used to specify an IP address for network testing.Affected if The pingip configuration field is present and accepts user input without authentication.
-
Verify web interface exposureDetermine if the pwrstudio interface is reachable from external networks by checking firewall rules, port exposures, or network segmentation. Confirm whether the management port is exposed to untrusted networks.Affected if The pwrstudio web interface is exposed to the internet or untrusted networks without IP restrictions.
A user is affected if the Raption EV charger runs pwrstudio firmware version 5.6.2 or lower AND the web interface with its ntpserver0, ntpserver1, and pingip configuration fields is accessible without authentication.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor-supplied firmware patch (version 5.6.3 or later) to address the command injection vectors. If patching is immediately unavailable, isolate the EV charger management network segment and restrict web interface access to trusted IPs only.
