Integrated Modem Poses Security Threat to Millions of IoT Devices


Millions of IoT Devices at Risk Due to Vulnerabilities in Cinterion Modems – Seven Severe Vulnerabilities and Mitigation Strategies

Millions of IoT Devices at Risk Due to Vulnerabilities in Cellular Modem Technology

A recent discovery by researchers from Kaspersky has revealed that millions of IoT devices across various sectors are at risk of compromise due to vulnerabilities in the cellular modem technology they rely on for communication. The vulnerabilities, predominantly found in Cinterion modems from Telit, pose a significant threat to industries such as financial services, telecommunications, healthcare, and automotive.

One of the most severe vulnerabilities, known as CVE-2023-47610, allows remote attackers to execute arbitrary code via SMS on affected devices. Telit has issued patches to address some of the flaws but not all, leaving many devices still vulnerable to exploitation.

Telit Cinterion modems are integrated into a wide range of IoT products, making it challenging to compile a comprehensive list of affected devices. The potential impact of these vulnerabilities is extensive, potentially leading to unauthorized access to sensitive data, operational disruptions, and threats to public safety and security.

To mitigate the risks associated with these vulnerabilities, Kaspersky recommends disabling nonessential SMS capabilities on vulnerable IoT devices and implementing private APNs with strict security settings. Telecom vendors also play a crucial role in preventing attackers from exploiting the vulnerability through network-level controls.

The rising concern over IoT security is further highlighted by a growing number of attacks targeting IoT and OT networks. It is essential for organizations to take proactive measures to secure their IoT devices and networks to prevent potential data breaches and operational disruptions.
