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-2020-8252 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- node (Bitnami): affected from 10.0.0; fixed in 10.22.1, 12.18.4, 14.9.0\n- node-min (Bitnami): affected from 10.0.0; fixed in 10.22.1, 12.18.4, 14.9.0\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-2020-8252/ (Markdown: https://insights.sbomify.com/CVE-2020-8252/index.md)","id":"CVE-2020-8252","markdown":"https://insights.sbomify.com/CVE-2020-8252/index.md","name":"CVE-2020-8252","record":{"aliases":["ALPINE-CVE-2020-8252","BIT-node-2020-8252","BIT-node-min-2020-8252","CLEANSTART-2026-MB55413","CLEANSTART-2026-OH78893","DEBIAN-CVE-2020-8252","GHSA-c5r6-cm8r-wgh9","MGASA-2020-0398","UBUNTU-CVE-2020-8252","USN-4548-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Node.js libuv","requires_auth":"low_privilege","summary":"A buffer overflow in libuv's realpath implementation allows attackers to execute arbitrary code or cause denial of service via long paths.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"fedora","vendor":"fedoraproject"},{"product":"node.js","vendor":"nodejs"},{"product":"leap","vendor":"opensuse"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"The implementation of realpath in libuv \u003c 10.22.1, \u003c 12.18.4, and \u003c 14.9.0 used within Node.js incorrectly determined the buffer size which can result in a buffer overflow if the resolved path is longer than 256 bytes.","ecosystems":["Bitnami"],"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":"Memory corruption in Node","id":"CVE-2020-8252","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"fedoraproject:fedora","products":["fedoraproject:fedora","nodejs:node.js","opensuse:leap"],"type":"memory_corruption","year":"2020"},"n_packages":2,"n_references":8,"next":{"headline":"Auth bypass in Citrix XenMobile Server","id":"CVE-2020-8253"},"packages":[{"ecosystem":"Bitnami","fixed":["10.22.1","12.18.4","14.9.0"],"introduced":["10.0.0","12.0.0","14.0.0"],"last_affected":[],"package":"node","purl":"pkg:bitnami/node","source":"BIT-node-2020-8252"},{"ecosystem":"Bitnami","fixed":["10.22.1","12.18.4","14.9.0"],"introduced":["10.0.0","12.0.0","14.0.0"],"last_affected":[],"package":"node-min","purl":"pkg:bitnami/node-min","source":"BIT-node-min-2020-8252"}],"prev":{"headline":"Denial of service in Node","id":"CVE-2020-8251"},"products":["Node"],"published":"2020-09-18","related":[{"cvss_score":9.8,"headline":"PHP-CGI OS Command Injection","id":"CVE-2024-4577","kev_date_added":"2024-06-12","published":"2024-06-09"},{"cvss_score":9.8,"headline":"Grafana Authentication Bypass","id":"CVE-2021-39226","kev_date_added":"2022-08-25","published":"2021-10-05"},{"cvss_score":9.8,"headline":"VMware ESXi and Horizon DaaS OpenSLP Heap-Based Buffer Overflow","id":"CVE-2019-5544","kev_date_added":"2021-11-03","published":"2019-12-06"},{"cvss_score":9.6,"headline":"Google Chromium V8 Type Confusion","id":"CVE-2024-4947","kev_date_added":"2024-05-20","published":"2024-05-15"},{"cvss_score":9.6,"headline":"Google Chromium Visuals Use-After-Free","id":"CVE-2024-4671","kev_date_added":"2024-05-13","published":"2024-05-09"},{"cvss_score":9.6,"headline":"Google Chromium Mojo Insufficient Data Validation","id":"CVE-2022-3075","kev_date_added":"2022-09-08","published":"2022-09-26"},{"cvss_score":9.6,"headline":"Google Chromium Indexed DB API Use-After-Free","id":"CVE-2021-30633","kev_date_added":"2021-11-03","published":"2021-10-08"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"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":"2025-04-30","vendors":["NodeJS"]},"summary":"A buffer overflow in libuv's realpath implementation allows attackers to execute arbitrary code or cause denial of service via long paths.","url":"https://insights.sbomify.com/CVE-2020-8252/"}
