{"id":"CVE-2020-3110","aliases":["EUVD-2020-24381","GHSA-f98q-m88w-x2r9"],"status":"published","title":"Cisco Video Surveillance 8000 Series IP Cameras Cisco Discovery Protocol Remote Code Execution and Denial of Service Vulnerability","description":"A vulnerability in the Cisco Discovery Protocol implementation for the Cisco Video Surveillance 8000 Series IP Cameras could allow an unauthenticated, adjacent attacker to execute code remotely or cause a reload of an affected IP Camera. The vulnerability is due to missing checks when processing Cisco Discovery Protocol messages. An attacker could exploit this vulnerability by sending a malicious Cisco Discovery Protocol packet to the targeted IP Camera. A successful exploit could allow the attacker to expose the affected IP Camera for remote code execution or cause it to reload unexpectedly, 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). This vulnerability is fixed in Video Surveillance 8000 Series IP Camera Firmware Release 1.0.7 and later.","severity":{"version":"3.0","score":8.8,"vector":"CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","level":"high","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-11","score":0.05728,"percentile":0.93142,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-20"],"published":"2020-02-05T17:35:14Z","modified":"2026-06-17T03:17:21Z","products":[{"vendor":"cisco","product":"cisco video surveillance 8000 series ip cameras"},{"vendor":"cisco","product":"video_surveillance_8000p_ip_camera_firmware"},{"vendor":"cisco","product":"video_surveillance_8020_ip_camera_firmware"},{"vendor":"cisco","product":"video_surveillance_8030_ip_camera_firmware"},{"vendor":"cisco","product":"video_surveillance_8070_ip_camera_firmware"},{"vendor":"cisco","product":"video_surveillance_8400_ip_camera_firmware"},{"vendor":"cisco","product":"video_surveillance_8620_ip_camera_firmware"},{"vendor":"cisco","product":"video_surveillance_8630_ip_camera_firmware"},{"vendor":"cisco","product":"video_surveillance_8930_speed_dome_ip_camera_firmware"}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20200205-ipcameras-rce-dos","tags":["vendor-advisory","x_refsource_CISCO","x_transferred","Vendor Advisory"]},{"url":"http://packetstormsecurity.com/files/156203/Cisco-Discovery-Protocol-CDP-Remote-Device-Takeover.html","tags":["x_refsource_MISC","x_transferred","Third Party Advisory","VDB Entry"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2020-3110"},{"url":"https://github.com/advisories/GHSA-f98q-m88w-x2r9"}],"sources":{"cve":[{"id":"CVE-2020-3110","title":"Cisco Video Surveillance 8000 Series IP Cameras Cisco Discovery Protocol Remote Code Execution and Denial of Service Vulnerability","description":"A vulnerability in the Cisco Discovery Protocol implementation for the Cisco Video Surveillance 8000 Series IP Cameras could allow an unauthenticated, adjacent attacker to execute code remotely or cause a reload of an affected IP Camera.
