CVSS v3.1

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 )

Risk Analysis

The Syrus4 IoT gateway uses an unsecured MQTT server, allowing unauthenticated remote attackers to execute arbitrary system commands and access sensitive device data. This critical vulnerability poses a severe risk to physical vehicle control and diagnostic data privacy.

No public exploit is currently known, and it is not in CISA KEV. The vulnerability is remotely exploitable with low attack complexity.

Recommended Action

Ensure the device firmware is updated to address the MQTT server security configuration. Restrict network access to the device to prevent unauthorized connections.

Generated by the CTIWATCH analysis pipeline from this CVE's metadata (CVSS, EPSS, KEV status, exploit intelligence). Verify against vendor advisories before acting.

Technical Analysis

CVE-2023-6248 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
