Description

A vulnerability in the networking component of Cisco access point (AP) software could allow an unauthenticated, remote attacker to cause a temporary disruption of service. This vulnerability is due to overuse of AP resources. An attacker could exploit this vulnerability by connecting to an AP on an affected device as a wireless client and sending a high rate of traffic over an extended period of time. A successful exploit could allow the attacker to cause the Datagram TLS (DTLS) session to tear down and reset, causing a denial of service (DoS) condition.

Affected configurations

• cisco catalyst 9166 firmware (< 17.6.6) • cisco catalyst 9164 firmware (< 17.6.6) • cisco catalyst 9136 firmware (< 17.6.6) • cisco catalyst 9130 firmware (< 17.6.6) • cisco catalyst 9124 firmware (< 17.6.6)
