It appears to be of the family Anyphaenidae - can be called 'Ghost spiders'.
These spiders are active climbers and can run very fast. Actually you saying it can climb glass is useful to ensure it likely has scopulate hair pads on the feet - which is a useful characteristic to help ensure identification.
Beautiful photographs by the way. A useful addition in this case would have been a photograph of the ventral abdomen, as for these it's often possible to see a split region which is entry of breathing tubes - tracheae. Most spiders only breath through book lungs - flat plates for gas exchange, but some have extra breathing tubes, and for Anyphaenidae the position of the entry of the air.
I cant go more specific on the identification, there's at least 23 species of the family in Colombia, in several genera. A couple can be ruled out, but most cannot from just photographs - sorry but spiders are often very poorly studied - a formal description of some characters may exist, but only in Europe and USA do we have 'field guides' and 'photo-guides' helping people match things they find.
Here you can find an overview of the family and access to papers on particular species, but the literature gets very technical very quickly.
