Name of the Vulnerable Software and Affected Versions Cisco Wireless LAN Controller version 8.3.102.0

Description A vulnerability in RADIUS Change of Authorization (CoA) request processing could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition by disconnecting a single connection. The issue is due to a lack of proper input validation of the RADIUS CoA packet header. An attacker could exploit this by sending a crafted RADIUS CoA packet to a targeted device, allowing them to disconnect a connection through the WLC unexpectedly.
