Description

A vulnerability in Cisco Aironet Access Points (APs) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) on an affected device. The vulnerability is due to improper resource management while processing specific packets. An attacker could exploit this vulnerability by sending a series of crafted UDP packets to a specific port on an affected device. A successful exploit could either allow the attacker to tear down the connection between the AP and the wireless LAN controller, resulting in the affected device not being able to process client traffic, or cause the vulnerable device to reload, triggering a DoS condition. After the attack, the affected device should automatically recover its normal functions without manual intervention.

Affected configurations

• cisco wireless lan controller (>= 8.9 < 8.10.112.0) • cisco wireless lan controller software (< 8.5.161.0) • cisco wireless lan controller software (>= 8.6 < 8.8.130.0) • cisco business access points (>= 10.0 < 10.1.1.0) • cisco access points (< 16.12.4a) • cisco aironet access point software 8.5\(154.27\) • cisco aironet access point software 8.8\(125.0\) • cisco aironet access point software 8.10\(105.0\) • cisco aironet access point software 8.10\(105.4\) • cisco aironet access point software 17.1.2.6 • cisco aironet access point software 17.1.2.9 • cisco aironet access point software 17.2.0.37
