Two-Factor Authentication Bypass in Citrix ShareFile by Citrix

CVE-2019-7218

Summary

Citrix ShareFile prior to version 19.23 has a vulnerability that allows attackers to bypass two-factor authentication by leveraging offline access to the user's one-time password (OTP) token. If an attacker acquires either the physical OTP token or the virtual application such as Google Authenticator, they can skip the first phase of authentication (username and password) and directly log in using only the username and OTP. This poses a significant risk to user accounts and sensitive information stored within the application.
