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-2021-1597 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-2021-1597/ (Markdown: https://insights.sbomify.com/CVE-2021-1597/index.md)","id":"CVE-2021-1597","markdown":"https://insights.sbomify.com/CVE-2021-1597/index.md","name":"CVE-2021-1597","record":{"aliases":["GHSA-v4r3-25fr-99fj"],"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":"Unauthenticated adjacent attackers can cause a denial of service on Cisco Video Surveillance IP cameras by sending crafted LLDP packets that trigger a memory leak.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"video_surveillance_7070_firmware","vendor":"cisco"},{"product":"video_surveillance_7530pd_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"}],"description":"Multiple vulnerabilities in the Link Layer Discovery Protocol (LLDP) implementation for Cisco Video Surveillance 7000 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. These vulnerabilities are due to incorrect processing of certain LLDP packets at ingress time. An attacker could exploit these vulnerabilities by sending crafted LLDP 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: 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":"Cisco Video Surveillance 7000 Series IP Cameras Link Layer Discovery Protocol Memory Leak Vulnerabilities","id":"CVE-2021-1597","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco Video Surveillance 7000 Series IP Cameras Link Layer Discovery Protocol Memory Leak Vulnerabilities","id":"CVE-2021-1598"},"packages":[],"prev":{"headline":"Cisco Video Surveillance 7000 Series IP Cameras Link Layer Discovery Protocol Memory Leak Vulnerabilities","id":"CVE-2021-1596"},"products":["Cisco Video Surveillance 7000 Series IP Cameras"],"published":"2021-07-08","related":[{"cvss_score":6.5,"headline":"Cisco Video Surveillance 7000 Series IP Cameras Link Layer Discovery Protocol Memory Leak Vulnerabilities","id":"CVE-2021-1595","kev_date_added":null,"published":"2021-07-08"},{"cvss_score":6.5,"headline":"Cisco Video Surveillance 7000 Series IP Cameras Link Layer Discovery Protocol Memory Leak Vulnerabilities","id":"CVE-2021-1596","kev_date_added":null,"published":"2021-07-08"},{"cvss_score":6.5,"headline":"Cisco Video Surveillance 7000 Series IP Cameras Link Layer Discovery Protocol Memory Leak Vulnerabilities","id":"CVE-2021-1598","kev_date_added":null,"published":"2021-07-08"},{"cvss_score":6.5,"headline":"Denial of service in Cisco Video Surveillance 7000 Series IP Cameras","id":"CVE-2021-1563","kev_date_added":null,"published":"2021-06-04"},{"cvss_score":6.5,"headline":"Denial of service in Cisco Video Surveillance 7000 Series IP Cameras","id":"CVE-2021-1564","kev_date_added":null,"published":"2021-06-04"}],"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":"Unauthenticated adjacent attackers can cause a denial of service on Cisco Video Surveillance IP cameras by sending crafted LLDP packets that trigger a memory leak.","url":"https://insights.sbomify.com/CVE-2021-1597/"}
