It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-3544 and fix it if it is affected.\n\nWhat it is: CVE-2020-3544 is a high-severity memory corruption vulnerability in Cisco Video Surveillance 8000 Series IP Cameras, published on 8 Oct 2020. 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-2020-3544 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-2020-3544/ (Markdown: https://insights.sbomify.com/CVE-2020-3544/index.md)","id":"CVE-2020-3544","markdown":"https://insights.sbomify.com/CVE-2020-3544/index.md","name":"CVE-2020-3544","record":{"aliases":["GHSA-g7gf-hwm5-m89c"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"IP camera","requires_auth":"none","summary":"An adjacent attacker can execute arbitrary code or cause a denial of service on Cisco Video Surveillance IP cameras via malicious CDP packets.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"A vulnerability in the Cisco Discovery Protocol implementation for Cisco Video Surveillance 8000 Series IP Cameras could allow an unauthenticated, adjacent attacker to execute arbitrary code on an affected device or cause the device to reload. This vulnerability is due to missing checks when an IP camera processes a Cisco Discovery Protocol packet. An attacker could exploit this vulnerability by sending a malicious Cisco Discovery Protocol packet to an affected device. A successful exploit could allow the attacker to execute code on the affected IP camera 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 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":"Memory corruption in Cisco Video Surveillance 8000 Series IP Cameras","id":"CVE-2020-3544","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco FXOS Software Buffer Overflow Vulnerability","id":"CVE-2020-3545"},"packages":[],"prev":{"headline":"Cisco Video Surveillance 8000 Series IP Cameras Cisco Discovery Protocol Memory Leak Vulnerability","id":"CVE-2020-3543"},"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-2020-3506","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-2020-3543","kev_date_added":null,"published":"2020-10-08"},{"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":"total"},"state":"PUBLISHED","updated":"2024-11-13","vendors":["Cisco"]},"summary":"An adjacent attacker can execute arbitrary code or cause a denial of service on Cisco Video Surveillance IP cameras via malicious CDP packets.","url":"https://insights.sbomify.com/CVE-2020-3544/"}
