Cisco Unified IP Phone 9951

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.

Cisco IP Phone Duplicate Key Vulnerability

Cisco 9900 fourth-generation IP phones do not properly perform SDP negotiation, which allows remote attackers to cause a denial of service (device reboot) via crafted SDP packets, aka Bug ID CSCuf06698.

The firmware on Cisco Unified IP phones 8961, 9951, and 9971 uses weak permissions for memory block devices, which allows local users to gain privileges by mounting a device with a setuid file in its filesystem, aka Bug ID CSCui04382.

The image-upgrade functionality on Cisco 9900 Unified IP phones allows local users to gain privileges by placing shell commands in an unspecified parameter, aka Bug ID CSCuh10334.

Cisco 9900 Unified IP phones allow remote attackers to cause a denial of service (unregistration) via a crafted SIP header, aka Bug ID CSCul24898.

Cisco IP Phones Series 7800 and Series 8800 Call Log Information Disclosure Vulnerability

The mobility extension on Cisco Unified IP 9900 phones with firmware 9.4(.1) and earlier allows remote attackers to cause a denial of service (logoff) via crafted packets, aka Bug ID CSCuq12139.

Buffer overflow in the web-application interface on Cisco 9900 IP phones allows remote attackers to cause a denial of service (webapp interface outage) via long values in unspecified fields, aka Bug ID CSCuh10343.

The mobility extension on Cisco Unified IP 9900 phones with firmware 9.4(.1) and earlier allows remote attackers to obtain sensitive information by sniffing the network, aka Bug ID CSCuq12117.

The web framework on Cisco Unified IP 9900 phones with firmware 9.4(.1) and earlier allows remote attackers to upload files to arbitrary locations on a phone's filesystem via crafted HTTP requests, aka Bug ID CSCup90424.

The Serviceability servlet on Cisco 9900 IP phones does not properly restrict paths, which allows remote attackers to read arbitrary files by specifying a pathname in a file request, aka Bug ID CSCuh52810.

Cisco Unified IP 9900 phones with firmware 9.4(.1) and earlier allow local users to cause a denial of service (device reload) via crafted commands, aka Bug ID CSCup92790.

Cisco Unified IP 9900 phones with firmware 9.4(.1) and earlier use weak permissions for unspecified files, which allows local users to cause a denial of service (persistent hang or reboot) by writing to a phone's filesystem, aka Bug ID CSCup90474.
