Cisco 1000 Series Connected Grid Router Integrated Wireless Access Point Denial of Service Vulnerability

<p>A vulnerability in the integrated wireless access point (AP) packet processing of the Cisco&nbsp;1000 Series Connected Grid Router (CGR1K) could allow an unauthenticated, adjacent attacker to cause a denial of service condition on an affected device.</p>
<p>This vulnerability is due to insufficient input validation of received traffic. An attacker could exploit this vulnerability by sending crafted traffic to an affected device. A successful exploit could allow the attacker to cause the integrated AP to stop processing traffic, resulting in a DoS condition. It may be necessary to manually reload the CGR1K to restore AP operation.</p>
<p>Cisco&nbsp;has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.</p>
