Telecom Security / Vulnerability
A group of academics has disclosed details of over 100 security vulnerabilities impacting LTE and 5G implementations that could be exploited by an attacker to disrupt access to service and even gain a foothold into the cellular core network. The 119 vulnerabilities , assigned 97 unique CVE identifiers, span seven LTE implementations – Open5GS , Magma , OpenAirInterface , Athonet , SD-Core , NextEPC , srsRAN – and three 5G implementations – Open5GS, Magma, OpenAirInterface, according to researchers from the University of Florida and North Carolina State University. The findings have been detailed in a study titled "RANsacked: A Domain-Informed Approach for Fuzzing LTE and 5G RAN-Core Interfaces." "Every one of the >100 vulnerabilities discussed below can be used to persistently disrupt all cellular communications (phone calls, messaging and data) at a city-wide level," the researchers said. "An attacker can continuously crash the Mobility Management En...
