#[https://threatpost.com/linux-bug-vpns-hijacking/150891/ Linux Bug Opens Most VPNs to Hijacking] - ''According to researchers at University of New Mexico and Breakpointing Bad, the bug (CVE-2019-14899), “allows…an attacker to determine if…a user is connected to a VPN, the virtual IP address they have been assigned by the VPN server, and whether or not there is an active connection to a given website.” In an advisory released this week, they noted that once a proof-of-concept exploit allowed them to determine a VPN client’s virtual IP address and make inferences about active connections, they were then able to use encrypted replies to unsolicited packets to determine the sequence and acknowledgment numbers of connections. These allowed them to hijack TCP sessions and inject data into the TCP stream.''
