looks normal to me- if the boot had a crack/hole in it u would have thick grease slime all over the place. cv boots do have and get a grease film on the outside to keep them from making a rubber squeaky noise.
Doesn't look like any grease from the boot to me. I hone one of my boots tear open and fixed under warranty. It slung dark brown grease everywhere. Took forever to get it all off.
