Critical Vulnerability in Syrus4 IoT Gateway Puts Millions of Drivers at Risk

Read Time:2 Minute, 17 Second

In the vast and interconnected world of modern vehicles, a silent threat has emerged, putting the safety of millions of drivers at risk. A critical vulnerability, identified as CVE-2023-6248, has been discovered in the Syrus4 IoT Telematics Gateway, a technology embedded in over 119,000 vehicles across 49 countries. Developed by Digital Communications Technologies (DCT), the Syrus4 IoT Gateway flaw, assigned a maximum CVSS score of 10.0, exposes a potential Pandora’s box of chaos, leaving millions of drivers vulnerable to hacking.

At the core of this alarming revelation is a flaw in the Syrus4 IoT Telematics Gateway’s version 23.43.2, unearthed by cybersecurity expert Yashin Mehaboobe from Xebia. This vulnerability transcends the typical exploits targeting individual vehicles; instead, it opens the door for attackers to remotely take control of entire fleets. Such an intrusion could lead to widespread chaos and, in the worst-case scenario, even accidents.

The gravity of CVE-2023-6248 lies in its ability to compromise the backend infrastructure, allowing attackers to manipulate software managing fleets of vehicles simultaneously. Unlike traditional vehicle exploits, this vulnerability grants unauthorized access to the Syrus4 IoT Gateway’s software, providing control over live locations, engine diagnostics, speakers, airbags, and the execution of arbitrary code on compromised devices.

The Achilles’ heel in this scenario is the critical issue in MQTT Server functionality, leading to improper authentication vulnerabilities. The unsecured MQTT server serves as a vulnerable entry point for remote, unauthenticated attackers, making it a potential breeding ground for malicious activities.

One of the most disconcerting features of Syrus4 is its capacity to remotely shut down vehicles. A cursory search revealed over 4,000 real-time vehicles connected to the server across the United States and Latin America. Despite the severity of this flaw, Digital Communications Technologies’ (DCT) response has been notably slow, raising concerns about the overall preparedness of industry leaders in addressing cybersecurity threats.

While awaiting a patch to rectify this critical vulnerability, proactive steps can be taken to mitigate risks. Users are advised to contact their fleet management companies to inquire about their security practices, exercise caution in using features reliant on the Syrus4 system (such as remote vehicle shutdown), and stay informed about the latest developments surrounding this vulnerability.

The situation underscores a pressing need for the automotive industry to prioritize and take robust measures regarding cybersecurity. With millions of drivers at risk of having their vehicles hacked, the potential consequences are nothing short of devastating. An urgent call is extended to DCT to take immediate action in rectifying this vulnerability and safeguarding the safety of their customers. In a world where innovation and connectivity define the automotive landscape, security must not be an afterthought but a cornerstone of technological advancement.
