What is CVE-2024-43660?
CVE-2024-43660 is a high-severity path traversal vulnerability in Iocharger firmware for AC models, published on 9 Jan 2025. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
The CGI script <redacted>.sh can be used to download any file on the filesystem.
This issue affects Iocharger firmware for AC model chargers beforeversion 24120701.
Likelihood: High, but credentials required.
Impact: Critical – The script can be used to download 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).
Weakness: CWE-552
