## What is CVE-2024-39915?

CVE-2024-39915 is a critical command injection vulnerability in sni Thruk, published on 15 Jul 2024. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

Thruk is a multibackend monitoring webinterface for Naemon, Nagios, Icinga and Shinken using the Livestatus API. This authenticated RCE in Thruk allows authorized users with network access to inject arbitrary commands via the URL parameter during PDF report generation. The Thruk web application does not properly process the url parameter when generating a PDF report. An authorized attacker with access to the reporting functionality could inject arbitrary commands that would be executed when the script /script/html2pdf.sh is called. The vulnerability can be exploited by an authorized user with network access. This issue has been addressed in version 3.16. Users are advised to upgrade. There are no known workarounds for this vulnerability.

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

What it is: CVE-2024-39915 is a critical command injection vulnerability in sni Thruk, published on 15 Jul 2024. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2024-39915 exists.

Affected product: sni Thruk. 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.
