If it is torn, the CV joint may be contaminated with water, salt, dirt. Quite a bit of the grease in the joint could have been thrown out of the boot. Look around, on the wheel and other places where it might have been thrown. Dirt damages the joint pretty quickly, so the axle will likely need replacement. That is the worst case scenario, that is if the boot has been torn long enough to get severely contaminated.
That being said, I had mine outer joint boot (same as yours) cracked for about a week or two, roughly 300km. Granted, this was on a different car, 7th gen Corolla with 150000km, but my point is that a damaged boot does not necessarily mean disaster right away. The boot was not torn wide open but it cracked on the side. I noticed some grease got thrown on the inside of the wheel. I took off the axle and upon inspection, the joint did not show scoring etc, so I just cleaned it thoroughly, flushed it with brake cleaner. Put a new boot on, new grease, back on car. That was 4 years ago, and I put 120.000km on it since. No problems.
