To circumvent part of it client-side, run the following command in your macOS shell (for example by using Terminal.app) every boot after connecting to the school's network and enter your password and press enter when prompted: sudo arp -s 10.2.191.253 00:40:96:52:7d:d3 Additionally, use https://sjauth.ykpaoschool.cn:444/ instead of http://1.1.1.3/ for authentication. A full vulnerability report will be published here once the school correctly addresses them.
