It was found that the internal TLS code in wget does not implement validation of the server's certificate.

Comment 4 Tomas Hoger 2018-06-28 03:27:04 EDT

The support for https in busybox's wget was first added in version 1.23.0.  The version of busybox in Red Hat Enterprise Linux 6 and earlier are based on older upstream busybox versions and do not support https at all.
