Just the best thing to do is focus on a point on the other end and ride to it. Correct if they start veering all over like a drunk person but concentrate on making sure you aren't favoring one side or the other (seat bones, leaning, stretching one leg down more, etc.) and forward forward forward!
Weaving is EXACTLY what "Corporal" (1982-2009,RIP) did when I first rode him as a 4yo. After a few years under saddle I could ride a 12" path with him, all gaits and side-pass back and forth over it, etc. You have to teach the horse to use his "rear wheel drive" to control his body.
