Hotfix for Biztalk Server SFTP Adaptor

Xing Liu 20

I am attempting to update winscp version used by Biztalk 2020 to 6.3.3 to account for security fix for CVE-2024-31497.

I am getting error:

Application: BTSNTSvc64.exe

Framework Version: v4.0.30319

Description: The process was terminated due to an unhandled exception.

Exception Info: System.MissingMethodException

at Microsoft.BizTalk.Adapter.Sftp.SftpFileReceiver.PollSftpServer()

When attempting to substitute in the version 6.3.3 dll using assembly redirect. Send ports work, but receive ports do not.

Is there a workaround for this or a hotfix coming?

We get the same error when using BizTalk 2020 CU5. We have tried Version 6.3.4 and 6.3.5 of WinSCP.

Ok after putting more energy into this all I had to do was go for the suggesten version on the CU5 update-page for WInSCP.
Version 6.1.2 seems to be working fine. (so the "or newer" seems to be a problem). I have also posted this info on the WinSCP forum. Still waiting for a response from there.
