Description

The vulnerability allows a remote attacker to bypass multifactor authentication.

The vulnerability exists due to the application allows push notification responses through the iOS ContextExtension feature, which leads to the victim confirming the authentication request regardless of the option selection. When a user long-presses the notification banner and selects an option, both options allow the authentication to succeed. A remote attacker with knowledge of the victim's password (or with ability to perform password spraying attack) can bypass second factor authentication and gain unauthorized access to the application protected with Okta Verify.
