I also just confirmed this works on CUCM 10.5.2:
Log in as platform admin
set password user security
Enter <what you suspect is old password>
Enter "cisco123" as new password
Confirm "cisco123" is new password
When prompted for DRS warning, hit "y"
First time my old password was wrong and got "The old password did not match"
Second time my old password was CORRECT and got "BAD PASSWORD: based on a dictionary word"
SUPER HELPFUL! Thanks so much gorourke!
