CVE-2021-1379 1 Cisco 55 Ip Conference Phone 7832, Ip Conference Phone 7832 Firmware, Ip Conference Phone 7832 With Multiplatform Firmware and 52 more 2026-01-06 6.5 Medium
Multiple vulnerabilities in the Cisco Discovery Protocol and Link Layer Discovery Protocol (LLDP) implementations for Cisco IP Phone Series 68xx/78xx/88xx could allow an unauthenticated, adjacent attacker to execute code remotely or cause a reload of an affected IP phone. These vulnerabilities are due to missing checks when the IP phone processes a Cisco Discovery Protocol or LLDP packet. An attacker could exploit these vulnerabilities by sending a malicious Cisco Discovery Protocol or LLDP packet to the targeted IP phone. A successful exploit could allow the attacker to execute code on the affected IP phone or cause it to reload unexpectedly, resulting in a denial of service (DoS) condition.Note: Cisco Discovery Protocol is a Layer 2 protocol. To exploit these vulnerabilities, an attacker must be in the same broadcast domain as the affected device (Layer 2 adjacent).Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.
CVE-2024-20378 1 Cisco 30 Ip Phone 6821, Ip Phone 6821 With Multiplatform Firmware, Ip Phone 6841 and 27 more 2026-01-05 7.5 High
A vulnerability in the web-based management interface of Cisco IP Phone firmware could allow an unauthenticated, remote attacker to retrieve sensitive information from an affected device.
