## What is CVE-2024-43658?

CVE-2024-43658 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

Patch traversal, External Control of File Name or Path vulnerability in  Iocharger Home allows deletion of arbitrary files
This issue affects Iocharger firmware for AC model before firmware version 25010801.

Likelihood: High, but requires authentication

Impact: Critical – The vulnerability can be used to delete any file on the charging station, severely impacting the integrity of the charging station. Furthermore, the vulnerability could be used to delete binaries required for the functioning of the charging station, severely impacting the availability of the charging station.

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 compromised of the integrity and availability of the device (VVC:N/VI:H/VA:H), with no effect on subsequent systems (SC:N/SI:N/SA:N). We do not forsee a safety impact (S:N). This attack can be automated (AU:Y).

Weakness: CWE-73 (External Control of File Name or Path), CWE-27 (Path Traversal: 'dir/../../filename')

Check this codebase for CVE-2024-43658 and fix it if it is affected.

What it is: CVE-2024-43658 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-2024-43658 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.
