An issue was discovered in Midnight Commander through 4.8.26. When establishing an SFTP connection, the fingerprint of the server is neither checked nor displayed. As a result, a user connects to the server without the ability to verify its authenticity.

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 ESM host has packages installed that are affected by a vulnerability as referenced in the USN-5160-1 advisory.

    It was discovered that Midnight Commander would not check server fingerprints when establishing an SFTP     connection. If a remote attacker were able to intercept communications this flaw could be exploited to     impersonate the SFTP server.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.
