AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N

Name of the Vulnerable Software and Affected Versions Citrix ShareFile versions prior to 19.23

Description The issue allows an attacker to downgrade from two-factor authentication to one-factor authentication. If an attacker has access to the victim's OTP physical token or virtual app, such as Google Authenticator, they can bypass the first authentication phase, which requires a username and password, and log in using only the username and OTP combination.

Recommendations For versions prior to 19.23, update to version 19.23 or later to resolve the issue. As a temporary workaround, consider restricting access to sensitive resources that use two-factor authentication until the update can be applied.
