Descriptions

A vulnerability was discovered in Linux, FreeBSD, OpenBSD, MacOS, iOS, and Android that allows a malicious access point, or an adjacent user, to determine if a connected user is using a VPN, make positive inferences about the websites they are visiting, and determine the correct sequence and acknowledgement numbers in use, allowing the bad actor to inject data into the TCP stream. This provides everything that is needed for an attacker to hijack active connections inside the VPN tunnel.

Se detectó una vulnerabilidad en Linux, FreeBSD, OpenBSD, MacOS, iOS y Android, que permite a un punto de acceso malicioso, o un usuario adyacente, determinar si un usuario conectado está utilizando una VPN, hacer inferencias positivas sobre los sitios web que está visitando, y determinar la secuencia correcta y los números de reconocimiento en uso, permitiendo al actor malo inyectar datos en la secuencia TCP. Esto proporciona todo lo necesario para que un atacante secuestre conexiones activas dentro del túnel VPN.
