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 · unedited
Improper Neutralization of Special Elements used in a Command ('Command Injection') vulnerability allows OS Command Injection as root This issue affects Iocharger firmware for AC model chargers before version 24120701. Likelihood: Moderate – It might be difficult for an attacker to identify the file structure of the <redated> directory, and then modify the backup to add a new CGI script in the correct directory. Furthermore, the attacker will need an account to restore the settings backup, or convince a user with such access to upload a modified backup file. Impact: Critical – The attacker has full control over the charging station as the root user, and can arbitrarily add, modify and deletefiles and services. CVSS clarification: Any network interface serving the web ui is vulnerable (AV:N) and there are not additional security measures to circumvent (AC:L), nor does the attack require and existing preconditions (AT:N). The attack is authenticated, but the level of authentication does not matter (PR:L), nor is any user interaction required (UI:N). The attack leads to a full compromised (VC:H/VI:H/VA:H), and compromised devices can be used to pivot into networks that should potentially not be accessible (SC:L/SI:L/SA:H). Becuase this is an EV charger handing significant power, there is a potential safety impact (S:P). This attack can be automated (AU:Y).

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 confidence

Iocharger AC model chargers before version 24120701 contain an OS command injection vulnerability in the settings backup/restore functionality. An authenticated attacker can modify a settings backup file to inject and execute arbitrary commands as root, achieving full device compromise.

MitigationUpdate Iocharger AC charger firmware to version 24120701 or later. If updating is not immediately possible, restrict network access to the web management interface to trusted sources only.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the device model
    Access the web management interface of the charger or check the device label to confirm it is an Iocharger AC model charger
    Affected if The device is not an Iocharger AC model charger
  2. Check the firmware version
    Log into the web management interface and navigate to the System Settings or About page to view the current firmware version. Compare this version number to 24120701
    Affected if The installed firmware version is lower than 24120701
  3. Verify web interface accessibility
    Determine if the web management interface is accessible from network locations. Check router/firewall rules or attempt to access the device IP from an untrusted network
    Affected if The web interface is exposed to untrusted networks and the firmware version is below 24120701
  4. Confirm authentication status
    Check whether default credentials are still in use or if the administrator account is accessible. Attempt to log into the web interface with valid credentials
    Affected if An attacker can authenticate to the device and the firmware version is below 24120701

The device is affected if it is an Iocharger AC model charger running firmware version lower than 24120701 with its web management interface accessible to the attacker.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Update Iocharger AC charger firmware to version 24120701 or later. If updating is not immediately possible, restrict network access to the web management interface to trusted sources only.

Recommended fix Moderate confidence

firmware version 24120701

  1. Contact Iocharger technical support or visit the official Iocharger website to obtain the firmware version 24120701 for your AC model charger
  2. Follow the vendor's documented firmware update procedure to apply version 24120701
  3. After upgrading, verify the firmware version is correctly installed
  4. Ensure the web interface is no longer exposed to untrusted networks if possible
