An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-8147 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- utils-extend (npm): affected from 0.0.0; no fix listed\n- utils-extend (npm): affected from 0.0.0; no fix listed\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-2020-8147/ (Markdown: https://insights.sbomify.com/CVE-2020-8147/index.md)","id":"CVE-2020-8147","markdown":"https://insights.sbomify.com/CVE-2020-8147/index.md","name":"CVE-2020-8147","record":{"aliases":["GHSA-6pq3-928q-x6w6"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"npm utils-extend library","requires_auth":"none","summary":"Prototype pollution in utils-extend allows attackers to achieve remote code execution or denial of service in applications using the library.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"utils-extend","vendor":"utils-extend_project"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"},{"id":"CWE-471","name":"Modification of Assumed-Immutable Data (MAID)"}],"description":"Flaw in input validation in npm package utils-extend version 1.0.8 and earlier may allow prototype pollution attack that may result in remote code execution or denial of service of applications using utils-extend.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Prototype Pollution","id":"CVE-2020-8147","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"code_injection","year":"2020"},"n_packages":2,"n_references":1,"next":{"headline":"Auth bypass in UniFi Cloud Key Gen2","id":"CVE-2020-8148"},"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0.0.0"],"last_affected":[],"package":"utils-extend","purl":null,"source":"GHSA-6pq3-928q-x6w6"},{"ecosystem":"npm","fixed":[],"introduced":["0.0.0"],"last_affected":[],"package":"utils-extend","purl":"pkg:npm/utils-extend","source":"GHSA-6pq3-928q-x6w6"}],"prev":{"headline":"Privilege escalation in UniFi Video Controller (for Windows 7/8/10 x64)","id":"CVE-2020-8146"},"products":["utils-extend"],"published":"2020-04-03","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"Prototype pollution in utils-extend allows attackers to achieve remote code execution or denial of service in applications using the library.","url":"https://insights.sbomify.com/CVE-2020-8147/"}
