Summary
A vulnerability in Cisco Identity Services Engine (ISE) could allow an
authenticated, remote attacker to cause the affected system to stop processing
Remote Authentication Dial-In User Service (RADIUS) packets.
The vulnerability is due to improper implementation of deadlock code when the
system receives crafted RADIUS accounting packets from two different network
access servers (NASs). An attacker could exploit this vulnerability by
crafting RADIUS account packets and sending them to the affected system. An
exploit could allow the attacker to cause the RADIUS process to become
unresponsive, causing the affected system to stop processing RADIUS packets.
