Cisco: >> Unified Ip Phone 9951 Security Vulnerabilities
A vulnerability in Cisco Unified IP Phones could allow an unauthenticated, remote attacker to impersonate another user's phone if the Cisco Unified Communications Manager (CUCM) is in secure mode. This vulnerability is due to improper key generation during the manufacturing process that could result in duplicated manufactured keys installed on multiple devices. An attacker could exploit this vulnerability by performing a machine-in-the-middle attack on the secure communication between the phone and the CUCM. A successful exploit could allow the attacker to impersonate another user's phone. This vulnerability cannot be addressed with software updates. There is a workaround that addresses this vulnerability.

A vulnerability in the Web Access feature of Cisco IP Phones Series 7800 and Series 8800 could allow an unauthenticated, remote attacker to view sensitive information on an affected device. The vulnerability is due to improper access controls on the web-based management interface of an affected device. An attacker could exploit this vulnerability by sending malicious requests to the device, which could allow the attacker to bypass access restrictions. A successful attack could allow the attacker to view sensitive information, including device call logs that contain names, usernames, and phone numbers of users of the device.

A vulnerability in the Session Initiation Protocol (SIP) ingress packet processing of Cisco Unified IP Phone software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. The vulnerability is due to a lack of flow-control mechanisms in the software. An attacker could exploit this vulnerability by sending high volumes of SIP INVITE traffic to the targeted device. Successful exploitation could allow the attacker to cause a disruption of services on the targeted IP phone. Cisco Bug IDs: CSCve10064, CSCve14617, CSCve14638, CSCve14683, CSCve20812, CSCve20926, CSCve20945.
