Cadogan linked up with the League Two side on a three-month deal in late September having seen his contract at Crystal Palace cancelled by mutual consent back in the summer.
The 22-year-old has suitably impressed during 15 appearances for the Shots, providing five assists for each of the club's five goals in their last two games, including all three for Danny Hylton's hat-trick in the FA Cup triumph over Rotherham.
Cadogan told Aldershot's official website: "Playing regularly in a team will be good for my career progression and I am looking forward to helping the team move up the table."
Manager Dean Holdsworth added: "I am absolutely delighted with this signing. Since he has been with us Kieron has grown in confidence and really adapted to our style of play.
"His quality of deliveries have been superb and he will improve because he is hungry to do so. I am delighted he has committed to the club."
