## What is CVE-2019-10669?

CVE-2019-10669 is a high-severity command injection vulnerability in Librenms Librenms, published on 9 Sep 2019. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

An issue was discovered in LibreNMS through 1.47. There is a command injection vulnerability in html/includes/graphs/device/collectd.inc.php where user supplied parameters are filtered with the mysqli_escape_real_string function. This function is not the appropriate function to sanitize command arguments as it does not escape a number of command line syntax characters such as ` (backtick), allowing an attacker to inject commands into the variable $rrd_cmd, which gets executed via passthru().

Weakness: CWE-78 (Improper Neutralization of Special Elements used in an OS Command)

```text
Check this codebase for CVE-2019-10669 and fix it if it is affected.

What it is: CVE-2019-10669 is a high-severity command injection vulnerability in Librenms Librenms, published on 9 Sep 2019. 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-2019-10669 exists.

Affected product: Librenms Librenms. 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.
