Researchers Report 84 Flaws in 4G and 5G Cores, Including a Session Hijacking Flaw

Researchers from Singapore's Nanyang Technological University have identified a large number of security vulnerabilities in 4G and 5G core networks. These flaws could be exploited to launch denial-of-service attacks or hijack user sessions, allowing an attacker to take control of a user's network session. The vulnerabilities are described as a widespread class of flaws, suggesting a significant impact on the security of these networks. The study's findings highlight potential security risks in 4G and 5G core networks. A total of 84 flaws were reported by the researchers. The identified vulnerabilities could have serious consequences if exploited by attackers.
