Multiple vulnerabilities in Cisco IP Phone firmware could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition, gain unauthorized access, or view sensitive information on an affected system. For more information about these vulnerabilities, see the Details ["#details"] section of this advisory. Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.

A vulnerability in the web-based management interface of Cisco IP Phone firmware could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a DoS condition. This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by sending a crafted request to the web-based management interface of an affected device. A successful exploit could allow the attacker to cause the affected device to reload.
