Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.73%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
When aborting a SFTP connection, MobaXterm before v22.1 sends a hardcoded password to the server. The server treats this as an invalid login attempt which can result in a Denial of Service (DoS) for the user if services like fail2ban are used.
