Technical details
The vulnerability is a session binding weakness in FTP passive mode data transfer handling, where data connections are not cryptographically or logically tied to the authenticated control channel. An attacker on the network path can establish a data connection to the passive port without proving authentication on the control connection, potentially reading or modifying in-flight FTP transfers. Remediation would require explicit binding of passive data connections to their originating authenticated control session.
