A vulnerability in the Guest Portal login page of Cisco Identity Services Engine (ISE) could allow an unauthenticated, remote attacker to perform multiple login attempts in excess of the configured login attempt limit.

The vulnerability is due to insufficient server-side login attempt limit enforcement. An attacker could exploit this vulnerability by sending modified login attempts to the Guest Portal login page. An exploit could allow the attacker to perform brute-force password attacks on the ISE Guest Portal.

There are no workarounds that address this vulnerability.
