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-2021-34734 in the wild and no public exploit code.\n\nAffected product: Cisco Video Surveillance 7000 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-2021-34734/ (Markdown: https://insights.sbomify.com/CVE-2021-34734/index.md)","id":"CVE-2021-34734","markdown":"https://insights.sbomify.com/CVE-2021-34734/index.md","name":"CVE-2021-34734","record":{"aliases":["GHSA-v9rw-54r8-5m4q"],"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 firmware","requires_auth":"none","summary":"An unauthenticated adjacent attacker can cause a denial of service on Cisco Video Surveillance IP cameras by sending crafted LLDP packets.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"video_surveillance_7000_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-415","name":"Double Free"}],"description":"A vulnerability in the Link Layer Discovery Protocol (LLDP) implementation for the Cisco Video Surveillance 7000 Series IP Cameras firmware could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition. This vulnerability is due to improper management of memory resources, referred to as a double free. An attacker could exploit this vulnerability by sending crafted LLDP packets to an affected device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition. Note: LLDP 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).","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":"Use after free in Cisco Video Surveillance 7000 Series IP Cameras","id":"CVE-2021-34734","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco ATA 190 Series Analog Telephone Adapter Software Vulnerabilities","id":"CVE-2021-34735"},"packages":[],"prev":{"headline":"Cisco Prime Infrastructure and Cisco Evolved Programmable Network Manager Information Disclosure Vulnerability","id":"CVE-2021-34733"},"products":["Cisco Video Surveillance 7000 Series IP Cameras"],"published":"2021-08-18","related":[],"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":"2024-11-07","vendors":["Cisco"]},"summary":"An unauthenticated adjacent attacker can cause a denial of service on Cisco Video Surveillance IP cameras by sending crafted LLDP packets.","url":"https://insights.sbomify.com/CVE-2021-34734/"}
