Description

Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1586271

Description of problem:
Latest release at this time of Satellite (6.3.1) shows vulnerable for sweet32 attack (https://sweet32.info/)

Version-Release number of selected component (if applicable):
Satellite 6.3.1

How reproducible:
Everytime

Steps to Reproduce:
1. nmap -sT -PN -p 443 <SATELLITE> --script=ssl-enum-ciphers.nse
2.
3.

Actual results:
↪ nmap -sT -PN -p 443 satellite.example.com --script=ssl-enum-ciphers.nse
