Description
busybox wget as included in the busybox base image doesn't verify TLS certificate:
$ docker run -ti --rm busybox wget -q https://expired.badssl.com && echo $?
wget: note: TLS certificate validation not implemented
0
While it prints an warning, most people won't realize this and are at risk downloading (and often executing).
See also #64: I also tend to agree that for full TLS, people should rather use another base image. But in this case I'd suggest disable https support altogether. Better no https than https without certificate validation and people not being aware of that.
