Summary
CVE-2024-43660 is a high-severity Files or Directories Accessible to External Parties (CWE-552) vulnerability in Divd (inferred from references). Its CVSS base score is 7.1 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Automated Collection (T1119); ranked at the 47th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and AC-6 (Least Privilege) — see the control section below for these in your framework.

CVE-2024-43660 is a vulnerability in the Iocharger firmware for AC model chargers, affecting versions prior to 24120701. The issue stems from a CGI script, <redacted>.sh, that can be abused to download any file on the device's filesystem. This flaw is classified under CWE-552 (Files or Directories Accessible to External Parties) and has a CVSS 4.0 vector of AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/AU:Y, emphasizing high confidentiality impact with low-privilege authentication required.
An attacker with valid credentials can exploit this over any network connection where the charger's web interface is accessible, without needing user interaction or additional preconditions. Successful exploitation allows arbitrary file downloads, including sensitive data like /etc/shadow, CGI script source code, binaries, and configuration files, leading to critical confidentiality breaches. The CVSS 3.1 score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) underscores the network accessibility and high impact, though the attack is isolated to the device with no integrity, availability, or subsequent system effects.
Advisories from DIVD CSIRT detail the vulnerability at https://csirt.divd.nl/CVE-2024-43660/ and https://csirt.divd.nl/DIVD-2024-00035/, with the vendor site at https://iocharger.com. Mitigation involves updating to firmware version 24120701 or later to address the exposed CGI script.

any file on the filesystem, including sensitive files such as /etc/shadow, the CGI script source code or binaries and configuration files. CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/S:P/AU:Y CVSS clarification. The attack can be executed over any network connection the station is listening to and serves the web interface (AV:N), and there are no additional security measure sin place that need to be circumvented (AC:L), the attack does not rely on preconditions (AT:N). The attack does require authentication, but the level of authentication is irrelevant (PR:L), it does not require user interaction (UI:N). The confidentiality of all files of the devicd can be compromised (VC:H/VI:N/VA:N). There is no impact on subsequent systems. (SC:N/SI:N/SA:N). While this device is an EV charger handing significant amounts of power, this attack in isolation does not have a safety impact. The attack can be automated (AU:Y).

Mitigating Controls (NIST 800-53 r5) AI
AC-3 directly enforces authorization checks on access to files and directories, stopping unauthorized external exposure.
AC-6 limits granted privileges, reducing the chance that files or directories become reachable by external parties.
AC-4 enforces information flow rules that can block unauthorized external access to files or directories.

Enforcing least-privilege permissions and authorization policies directly prevents unauthorized file/directory exposure.
Data-at-rest protections such as encryption or ACLs reduce the impact of unintended file exposure.
Logical segmentation and access protections stop external parties from reaching files that should remain internal.
Hardened configuration baselines commonly include file-system permission settings that limit external access.
