Summary
A vulnerability in the Active Directory integration component of Cisco Identity Service Engine (ISE) could allow an unauthenticated, remote attacker to perform a denial of service attack.
Insight
Insight

An attacker could exploit this vulnerability by crafting a special but formally correct PAP authentication request that will trigger the issue. An exploit could allow the attacker to cause the failures of all subsequent authentication requests for the same Active Directory domain.
