Cybersecurity experts at universities and Big Tech have disclosed a vulnerability in a common client-server networking protocol that allows snoops to potentially bypass user authentication via man-in-the-middle (MITM) attacks. If the vulnerability, rated 7.5 out of 10 on the CVSS severity scale and tracked as CVE-2024-3596, is exploited – and it's not that easy to pull off – attackers could theoretically access to network devices and services without needing to obtain any credentials. It doe...
