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-2020-8157 in the wild and no public exploit code.\n\nAffected product: UniFi Cloud Key Gen2, Cloud Key Gen2 plus. 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-2020-8157/ (Markdown: https://insights.sbomify.com/CVE-2020-8157/index.md)","id":"CVE-2020-8157","markdown":"https://insights.sbomify.com/CVE-2020-8157/index.md","name":"CVE-2020-8157","record":{"aliases":["GHSA-3qh5-7339-m5xf"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"UniFi Cloud Key","requires_auth":"none","summary":"Attackers with physical access can gain unrestricted root privileges via the serial interface on UniFi Cloud Key devices.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"unifi_cloud_key_gen2_firmware","vendor":"ui"},{"product":"unifi_cloud_key_gen2_plus_firmware","vendor":"ui"}],"cvss":{"score":6.8,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"UniFi Cloud Key firmware \u003c= v1.1.10 for Cloud Key gen2 and Cloud Key gen2 Plus contains a vulnerability that allows unrestricted root access through the serial interface (UART).","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":"Auth bypass in UniFi Cloud Key Gen2, Cloud Key Gen2 plus","id":"CVE-2020-8157","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"TypeORM vulnerable to MAID and Prototype Pollution","id":"CVE-2020-8158"},"packages":[],"prev":{"headline":"Security feature bypass in Nextcloud Mail","id":"CVE-2020-8156"},"products":["UniFi Cloud Key Gen2, Cloud Key Gen2 plus"],"published":"2020-05-02","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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Attackers with physical access can gain unrestricted root privileges via the serial interface on UniFi Cloud Key devices.","url":"https://insights.sbomify.com/CVE-2020-8157/"}
