## What is CVE-2023-6248?

CVE-2023-6248 is a critical code injection vulnerability in Digital Communications Technologies Syrus4 IoT Telematics Gateway, published on 21 Nov 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

The Syrus4 IoT gateway utilizes an unsecured MQTT server to download and execute arbitrary commands, allowing a remote unauthenticated attacker to execute code on any Syrus4 device connected to the cloud service. The MQTT server also leaks the location, video and diagnostic data from each connected device. An attacker who knows the IP address of the server is able to connect and perform the following operations:

  *  Get location data of the vehicle the device is connected to
  *  Send CAN bus messages via the ECU module ( https://syrus.digitalcomtech.com/docs/ecu-1 https://syrus.digitalcomtech.com/docs/ecu-1 )

  *  Immobilize the vehicle via the safe-immobilizer module ( https://syrus.digitalcomtech.com/docs/system-tools#safe-immobilization https://syrus.digitalcomtech.com/docs/system-tools#safe-immobilization )

  *  Get live video through the connected video camera

  *  Send audio messages to the driver ( https://syrus.digitalcomtech.com/docs/system-tools#apx-tts https://syrus.digitalcomtech.com/docs/system-tools#apx-tts )

Weakness: CWE-94 (Improper Control of Generation of Code), CWE-319 (Cleartext Transmission of Sensitive Information), CWE-287 (Improper Authentication), CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor)

Check this codebase for CVE-2023-6248 and fix it if it is affected.

What it is: CVE-2023-6248 is a critical code injection vulnerability in Digital Communications Technologies Syrus4 IoT Telematics Gateway, published on 21 Nov 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2023-6248 in the wild and no public exploit code.

Affected product: Digital Communications Technologies Syrus4 IoT Telematics Gateway. 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.
