An issue was discovered in certain Apple products. macOS before 10.13 is affected. The issue involves the Captive Network Assistant component. It allows remote attackers to discover cleartext passwords in opportunistic circumstances by sniffing the network during use of the captive portal browser, which has a UI error that can lead to cleartext transmission without the users awareness.
The product transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors.
