Summary

Cisco Small Business Wireless Access Points contain a vulnerability that could allow an unauthenticated, adjacent attacker to impact the integrity and availability of services and data on the affected device.

The vulnerability is due to improper validation of the Service Set Identifier (SSID) when the affected product is performing a "site survey" to discover adjacent available networks. An attacker may be able to exploit this vulnerability by broadcasting a crafted SSID and convincing the administrator of the affected device to perform a site survey. A successful attack could cause a denial of service condition.

Additionally, there is the risk that the attacker could obtain the ability to override part of the memory of the affected device. However, the ability to override part of the memory is theoretical and could not be proven by Cisco.

What Is a Cisco Security Notice?

The Cisco Product Security Incident Response Team (PSIRT) publishes Cisco Security Notices to inform customers of low- to mid-level severity security issues involving Cisco products.

Customers who wish to upgrade to a software version that includes fixes for these issues should contact their normal support channels. Free software updates will not be provided for issues that are disclosed through a Cisco Security Notice.
