Cisco Small Business SPA3x/5x Series Denial of Service Vulnerability

Advisory ID: cisco-sa-20160831-spa

Revision 1.0

Summary
=======

A vulnerability in the HTTP framework of Cisco Small Business SPA300 Series IP Phones, Cisco Small Business SPA500 Series IP Phones, and Cisco SPA51x IP Phones could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.

The vulnerability is due to incorrect handling of malformed HTTP traffic. An attacker could exploit this vulnerability by sending crafted HTTP requests to an affected device. An exploit could allow the attacker to deny service continually by sending crafted HTTP requests to a phone, resulting in a DoS condition.

Cisco has released software updates that address this vulnerability. Workarounds that address this vulnerability are not available.
