Researchers Identify 84 Security Vulnerabilities in 4G and 5G Core Networks

Researchers from Nanyang Technological University discovered 84 vulnerabilities in 4G and 5G core networks, including session hijacking risks. The study highlights implicit trust errors in network functions, leading to potential DoS attacks and session manipulation, with 83 confirmed flaws addressed through CVE identifiers.

An academic study has disclosed a "widespread class" of security vulnerabilities impacting 4G and 5G core networks that, if successfully exploited, could trigger denial-of-service (DoS) attacks and even session hijacking, allowing an attacker to seize control of a user's network session.

The findings have been released by a group of researchers from Singapore's Nanyang Technological University
