It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-3543 in the wild and no public exploit code.\n\nAffected product: Cisco Video Surveillance 8000 Series IP Cameras. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2020-3543/ (Markdown: https://insights.sbomify.com/CVE-2020-3543/index.md)","id":"CVE-2020-3543","markdown":"https://insights.sbomify.com/CVE-2020-3543/index.md","name":"CVE-2020-3543","record":{"aliases":["GHSA-jmv5-wf84-2hgh"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"IP camera","requires_auth":"none","summary":"An adjacent attacker can cause a memory leak and device crash by sending crafted Cisco Discovery Protocol packets to Cisco Video Surveillance IP cameras.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"8000p_ip_camera_firmware","vendor":"cisco"},{"product":"8020_ip_camera_firmware","vendor":"cisco"},{"product":"8030_ip_camera_firmware","vendor":"cisco"},{"product":"8070_ip_camera_firmware","vendor":"cisco"},{"product":"8400_ip_camera_firmware","vendor":"cisco"},{"product":"8620_ip_camera_firmware","vendor":"cisco"},{"product":"8630_ip_camera_firmware","vendor":"cisco"},{"product":"8930_speed_dome_ip_camera_firmware","vendor":"cisco"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-401","name":"Missing Release of Memory after Effective Lifetime"},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"A vulnerability in the Cisco Discovery Protocol of Cisco Video Surveillance 8000 Series IP Cameras could allow an unauthenticated, adjacent attacker to cause a memory leak, which could lead to a denial of service (DoS) condition on an affected device. The vulnerability is due to incorrect processing of certain Cisco Discovery Protocol packets. An attacker could exploit this vulnerability by sending certain Cisco Discovery Protocol packets to an affected device. A successful exploit could allow the attacker to cause the affected device to continuously consume memory, which could cause the device to crash and reload, resulting in a DOS condition. Note: 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).","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Cisco Video Surveillance 8000 Series IP Cameras Cisco Discovery Protocol Memory Leak Vulnerability","id":"CVE-2020-3543","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in Cisco Video Surveillance 8000 Series IP Cameras","id":"CVE-2020-3544"},"packages":[],"prev":{"headline":"Cisco Webex Training Unauthorized Meeting Join Vulnerability","id":"CVE-2020-3542"},"products":["Cisco Video Surveillance 8000 Series IP Cameras"],"published":"2020-10-08","related":[{"cvss_score":8.8,"headline":"Memory corruption in Cisco Video Surveillance 8000 Series IP Cameras","id":"CVE-2020-3544","kev_date_added":null,"published":"2020-10-08"},{"cvss_score":8.8,"headline":"Memory corruption in Cisco Video Surveillance 8000 Series IP Cameras","id":"CVE-2020-3506","kev_date_added":null,"published":"2020-08-26"},{"cvss_score":8.8,"headline":"Memory corruption in Cisco Video Surveillance 8000 Series IP Cameras","id":"CVE-2020-3507","kev_date_added":null,"published":"2020-08-26"},{"cvss_score":6.5,"headline":"Cisco Video Surveillance 8000 Series IP Cameras Cisco Discovery Protocol Memory Leak Vulnerability","id":"CVE-2020-3505","kev_date_added":null,"published":"2020-08-26"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-11-13","vendors":["Cisco"]},"summary":"An adjacent attacker can cause a memory leak and device crash by sending crafted Cisco Discovery Protocol packets to Cisco Video Surveillance IP cameras.","url":"https://insights.sbomify.com/CVE-2020-3543/"}
