## What is CVE-2024-43363?

CVE-2024-43363 is a high-severity code injection vulnerability in Cacti Cacti, published on 7 Oct 2024. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

Cacti is an open source performance and fault management framework. An admin user can create a device with a malicious hostname containing php code and repeat the installation process (completing only step 5 of the installation process is enough, no need to complete the steps before or after it) to use a php file as the cacti log file. After having the malicious hostname end up in the logs (log poisoning), one can simply go to the log file url to execute commands to achieve RCE. This issue has been addressed in version 1.2.28 and all users are advised to upgrade. There are no known workarounds for this vulnerability.

Weakness: CWE-94 (Improper Control of Generation of Code)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2024-43363 and fix it if it is affected.

What it is: CVE-2024-43363 is a high-severity code injection vulnerability in Cacti Cacti, published on 7 Oct 2024. An attacker needs administrator access to exploit it, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2024-43363 exists.

Affected product: Cacti Cacti. 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.
