What could be a way to find the url to the CMS login?
first dont doubel post...
2 cpanel dossent store the password in the same db as the rest of the content as far as i know for security reasons
install an addon named wappalizer its for firefox. its a easy drop down menu with information about the site cms, os, php v, webserver, analytics, framework and so on
find the cms by addon or source of page or layout.
check where the login is from cmd source.
if there is no login consider uploading a shell via sql injection
