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-2021-44527 in the wild and no public exploit code.\n\nAffected product: UniFi Switches. 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-2021-44527/ (Markdown: https://insights.sbomify.com/CVE-2021-44527/index.md)","id":"CVE-2021-44527","markdown":"https://insights.sbomify.com/CVE-2021-44527/index.md","name":"CVE-2021-44527","record":{"aliases":["GHSA-2fpq-jhjc-vqfv"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"UniFi Switch","requires_auth":"none","summary":"A network-accessible attacker can cause a Denial of Service on UniFi Switches, requiring a firmware upgrade to mitigate.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"unifi_switch_firmware","vendor":"ui"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","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-400","name":"Uncontrolled Resource Consumption"}],"description":"A vulnerability found in UniFi Switch firmware Version 5.43.35 and earlier allows a malicious actor who has already gained access to the network to perform a Deny of Service (DoS) attack on the affected switch.This vulnerability is fixed in UniFi Switch firmware 5.76.6 and later.","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":"Denial of service in UniFi Switches","id":"CVE-2021-44527","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":"actionpack Open Redirect in Host Authorization Middleware","id":"CVE-2021-44528"},"packages":[],"prev":{"headline":"Auth bypass in n/a","id":"CVE-2021-44526"},"products":["UniFi Switches"],"published":"2021-12-07","related":[{"cvss_score":9,"headline":"Integer overflow in UniFi Access Points","id":"CVE-2023-35085","kev_date_added":null,"published":"2023-08-10"},{"cvss_score":8.3,"headline":"Command injection in UniFi Access Points","id":"CVE-2023-38034","kev_date_added":null,"published":"2023-08-10"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"A network-accessible attacker can cause a Denial of Service on UniFi Switches, requiring a firmware upgrade to mitigate.","url":"https://insights.sbomify.com/CVE-2021-44527/"}
