Summary
A vulnerability in Cisco Identity Services Engine (ISE) could allow an
unauthenticated, remote attacker to exhaust guest user account resources.
The vulnerability is due to a guest account creation page that allows
unlimited guest accounts to be created upon refreshing the page. An attacker
could exploit this vulnerability by creating a new guest account then
repeatedly refreshing the page until the maximum number of guest accounts
for the system is reached. An exploit could allow the attacker to deny
creation of other guest accounts.
