Conditions
SSH session logged in with local username that has privilege <15 running the 'show running-config' command.
This potentially affects any IOS-XE that does not have the fix integrated (not platform-specific).
Workaround
Configure affected local username with privilege level 15:
Device(config)#username cisco privilege 15
