## What is CVE-2023-31191?

CVE-2023-31191 is a critical denial of service vulnerability in bluemark ds230, published on 11 Jul 2023. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

DroneScout ds230 Remote ID receiver from BlueMark Innovations is affected by an information loss vulnerability through traffic injection.

An attacker can exploit this vulnerability by injecting, on carefully selected channels, high power spoofed Open Drone ID (ODID) messages which force the DroneScout ds230 Remote ID receiver to drop real Remote ID (RID) information and, instead, generate and transmit JSON encoded MQTT messages containing crafted RID information. Consequently, the MQTT broker, typically operated by a system integrator, will have no access to the drones’ real RID information.

This issue affects the adjacent channel suppression algorithm present in DroneScout ds230 firmware from version 20211210-1627 through 20230329-1042.

Weakness: CWE-223 (Omission of Security-relevant Information)

Check this codebase for CVE-2023-31191 and fix it if it is affected.

What it is: CVE-2023-31191 is a critical denial of service vulnerability in bluemark ds230, published on 11 Jul 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-2023-31191 in the wild and no public exploit code.

Affected product: bluemark ds230. 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.
