## What is CVE-2023-32349?

CVE-2023-32349 is a high-severity command injection vulnerability in Teltonika RUT model routers, published on 22 May 2023. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

Version 00.07.03.4 and prior of Teltonika’s RUT router firmware contain a packet dump utility that contains proper validation for filter parameters. However, variables for validation checks are stored in an external configuration file. An authenticated attacker could use an exposed UCI configuration utility to change these variables and enable malicious parameters in the dump utility, which could result in arbitrary code execution.

Weakness: CWE-15 (External Control of System or Configuration Setting)

Check this codebase for CVE-2023-32349 and fix it if it is affected.

What it is: CVE-2023-32349 is a high-severity command injection vulnerability in Teltonika RUT model routers, published on 22 May 2023. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2023-32349 in the wild and no public exploit code.

Affected product: Teltonika RUT model routers. 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.
