Background for this topic.

5G is the fifth generation mobile network technology designed to connect virtually everyone and everything together including machines, objects, and devices. It is engineered to provide higher multi-Gbps data speeds, ultra-low latency, more reliability, massive network capacity, increased availability, and a more uniform user experience to more users. With its advancements over previous generations, 5G is poised to enable a new kind of network that is designed to connect virtually everyone and everything together including machines, objects, and devices.In the context of information security, 5G introduces both opportunities and challenges. The technology's ability to support a vast number of connected devices amplifies the attack surface for malicious activities. Enhanced mobile broadband (eMBB), ultra-reliable low-latency communications (URLLC), and massive machine-type communications (mMTC) are foundational capabilities that could potentially be exploited if not properly secured. Conversely, 5G also brings robust security features, such as improved encryption, stronger user privacy mechanisms, and the potential for network slicing to allow for customized security policies. Adoption of 5G necessitates updated security protocols and strategies to address emerging threats and to leverage the technology's full potential for secure communication.

Vulnerabilities in Cellular Packet Cores Part IV: Authentication

Our research reveals two significant vulnerabilities in Microsoft Azure Private 5G Core (AP5GC). The first vulnerability (CVE-2024-20685) allows a crafted signaling message to crash the control plane, leading to potential service outages. The second (ZDI-CAN-23960) disconnects and replaces attached base stations, disrupting network operations. While these issues are implementation-specific, their exploitation is made possible by a systemic weakness: the lack of mandatory authentication procedures between base stations and packet-cores.

Attacks on 5G Infrastructure From Users’ Devices

Crafted packets from cellular devices such as mobile phones can exploit faulty state machines in the 5G core to attack cellular infrastructure. Smart devices that critical industries such as defense, utilities, and the medical sectors use for their daily operations depend on the speed, efficiency, and productivity brought by 5G. This entry describes CVE-2021-45462 as a potential use case to deploy a denial-of-service (DoS) attack to private 5G networks.
