CVE-2024-7745Network attack vector

MFA bypass via skipped second-factor verification

Published Aug 28, 2024 · Updated Aug 28, 2024

Authentication bypass in Progress WS_FTP Server before 8.8.8 allows remote authenticated users to access Web Transfer without MFA. The Web Transfer Module login flow accepts a valid username and password and establishes a session without completing the required second-factor verification. Exploitation requires credentials for an MFA-enabled account and grants access to that account's permitted files and transfer operations.
