Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of mc installed on the remote host is prior to 4.8.29-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-2147 advisory.

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. (CVE-2021-36370)
