## 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 (Files or Directories Accessible to External Parties)

```text
Check this codebase for CVE-2024-43660 and fix it if it is affected.

What it is: 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.
Exploitation: There is no known exploitation of CVE-2024-43660 in the wild and no public exploit code.

Affected product: Iocharger firmware for AC models. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
