CVE-2019-1635 1 Cisco 32 Ip Conference Phone 7832, Ip Conference Phone 7832 Firmware, Ip Conference Phone 8832 and 29 more 2020-10-16 7.8 HIGH 7.5 HIGH
A vulnerability in the call-handling functionality of Session Initiation Protocol (SIP) Software for Cisco IP Phone 7800 Series and 8800 Series could allow an unauthenticated, remote attacker to cause an affected phone to reload unexpectedly, resulting in a temporary denial of service (DoS) condition. The vulnerability is due to incomplete error handling when XML data within a SIP packet is parsed. An attacker could exploit this vulnerability by sending a SIP packet that contains a malicious XML payload to an affected phone. A successful exploit could allow the attacker to cause the affected phone to reload unexpectedly, resulting in a temporary DoS condition.
CVE-2020-3111 1 Cisco 54 Ip Conference Phone 7832, Ip Conference Phone 7832 Firmware, Ip Conference Phone 7832 With Multiplatform Firmware and 51 more 2020-02-07 8.3 HIGH 8.8 HIGH
A vulnerability in the Cisco Discovery Protocol implementation for the Cisco IP Phone could allow an unauthenticated, adjacent attacker to remotely execute code with root privileges or cause a reload of an affected IP phone. The vulnerability is due to missing checks when processing Cisco Discovery Protocol messages. An attacker could exploit this vulnerability by sending a crafted Cisco Discovery Protocol packet to the targeted IP phone. A successful exploit could allow the attacker to remotely execute code with root privileges or cause a reload of an affected IP phone, resulting in a denial of service (DoS) condition. Cisco Discovery Protocol is a Layer 2 protocol. To exploit this vulnerability, an attacker must be in the same broadcast domain as the affected device (Layer 2 adjacent).
CVE-2019-1922 1 Cisco 24 Ip Conference Phone 7832, Ip Conference Phone 7832 Firmware, Ip Conference Phone 8832 and 21 more 2019-10-09 7.8 HIGH 7.5 HIGH
A vulnerability in Cisco SIP IP Phone Software for Cisco IP Phone 7800 Series and 8800 Series could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected phone. The vulnerability is due to insufficient validation of input Session Initiation Protocol (SIP) packets. An attacker could exploit this vulnerability by altering the SIP replies that are sent to the affected phone during the registration process. A successful exploit could allow the attacker to cause the phone to reboot and not complete the registration process.
CVE-2018-0316 1 Cisco 13 Ip Phone 6841, Ip Phone 6851, Ip Phone 7811 and 10 more 2019-10-09 7.8 HIGH 7.5 HIGH
A vulnerability in the Session Initiation Protocol (SIP) call-handling functionality of Cisco IP Phone 6800, 7800, and 8800 Series Phones with Multiplatform Firmware could allow an unauthenticated, remote attacker to cause an affected phone to reload unexpectedly, resulting in a temporary denial of service (DoS) condition. The vulnerability exists because the firmware of an affected phone incorrectly handles errors that could occur when an incoming phone call is not answered. An attacker could exploit this vulnerability by sending a set of maliciously crafted SIP packets to an affected phone. A successful exploit could allow the attacker to cause the affected phone to reload unexpectedly, resulting in a temporary DoS condition. This vulnerability affects Cisco IP Phone 6800, 7800, and 8800 Series Phones with Multiplatform Firmware if they are running a Multiplatform Firmware release prior to Release 11.1(2). Cisco Bug IDs: CSCvi24718.
CVE-2018-0332 1 Cisco 27 Ip Phone 7811, Ip Phone 7821, Ip Phone 7841 and 24 more 2019-10-09 5.0 MEDIUM 7.5 HIGH
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.
CVE-2018-0341 1 Cisco 13 Ip Phone 6841, Ip Phone 6851, Ip Phone 7811 and 10 more 2019-10-09 9.0 HIGH 8.8 HIGH
A vulnerability in the web-based UI of Cisco IP Phone 6800, 7800, and 8800 Series with Multiplatform Firmware before 11.2(1) could allow an authenticated, remote attacker to perform a command injection and execute commands with the privileges of the web server. The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by including arbitrary shell commands in a specific user input field. Cisco Bug IDs: CSCvi51426.
