{"cve":"CVE-2020-3110","nvd":{"published":"2020-02-05T18:15:10.673","modified":"2026-06-17T03:17:21.733","status":"Modified","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-20"],"references":["http://packetstormsecurity.com/files/156203/Cisco-Discovery-Protocol-CDP-Remote-Device-Takeover.html","https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20200205-ipcameras-rce-dos","http://packetstormsecurity.com/files/156203/Cisco-Discovery-Protocol-CDP-Remote-Device-Takeover.html","https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20200205-ipcameras-rce-dos"],"products":["cisco:video_surveillance_8000p_ip_camera_firmware","cisco:video_surveillance_8020_ip_camera_firmware","cisco:video_surveillance_8030_ip_camera_firmware","cisco:video_surveillance_8070_ip_camera_firmware","cisco:video_surveillance_8400_ip_camera_firmware","cisco:video_surveillance_8620_ip_camera_firmware","cisco:video_surveillance_8630_ip_camera_firmware","cisco:video_surveillance_8930_speed_dome_ip_camera_firmware"],"source":"nvd","synced_at":"2026-10-19T21:02:53.949909883+00:00"},"epss":{"cve":"CVE-2020-3110","score":0.05728,"percentile":0.93045,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
