Imagine being able to take over a device without needing a physical touch, reaching deep into its operating system with just an SMS message. Sound like science fiction? It's not. It's a reality made possible by recent security flaws discovered in Telit Cinterion cellular modems.
The venerable and extensive use of Cinterion modems in sectors as diverse as industrial, healthcare, and telecommunications has recently been disrupted due to a set of eight security issues. With identifiers ranging from CVE-2023-47610 to CVE-2023-47616, these vulnerabilities were first brought to light last November by the Kaspersky's ICS CERT division, having been reported to the vendor at the beginning of 2023.
Last Saturday, at the OffensiveCon conference in Berlin, security experts Alexander Kozlov and Sergey Anufrienko offered in-depth technical presentations on these vulnerabilities, distinctly describing how they could be exploited to gain control of Telit Cinterion devices.
Leading the pack of these vulnerabilities is CVE-2023-47610, a heap overflow problem that impacts the modem’s User Plane Location (SUPL) message handlers. This flaw boasts a severity score of 8.8 out of the maximum 10, further elevated to 9.8 by NIST, categorizing it as having a critical impact.
The severity stems from the ability of perpetrators to manipulate the flaw through SMS messages that execute arbitrary code on the modem remotely. This would provide the attacker with deep-level access to the modem's OS and facilitate manipulation of the RAM and flash memory—essentially providing full control over the modem's functionalities—all without authentication or needing physical access to the device.
The outcome? Grave threats to data confidentiality, and integrity, network security, and device integrity. Furthermore, the same vulnerabilities could potentially undermine the integrity of MIDlets, a type of Java-based application with various functions.
The research specifically targeted the Cinterion EHS5-E series modem. However, other products sharing similar software and hardware architecture, such as Cinterion BGS5, Cinterion EHS5/6/7, Cinterion PDS5/6/8, Cinterion ELS61/81, and Cinterion PLS62, are impacted as well.
Telit has addressed some of the disclosed vulnerabilities, albeit some persist unpatched, as reported by Kaspersky to BleepingComputer.
The need for robust cyber defensive measures against such potential attacks is evident. We must strive to continually enhance and reinforce our security procedures. While innovation can open numerous doors to progress and convenience, it invariably brings new vulnerability surfaces. Regardless front-end tech-savviness or not, old gamer or parent investing in gadgets for young ones, the need for security vigilance is universal in an era of Internet connectivity.
The story of Telit Cinterion cellular modems and its vulnerabilities is a far-reaching reminder that security ought to be a priority, whether you’re a global enterprise, a budding start-up, a sector-specific institution, or a gadget-loving individual. Let's stay woke, guys!
