It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2020-36657 exists.\n\nAffected product: n/a. 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-2020-36657/ (Markdown: https://insights.sbomify.com/CVE-2020-36657/index.md)","id":"CVE-2020-36657","markdown":"https://insights.sbomify.com/CVE-2020-36657/index.md","name":"CVE-2020-36657","record":{"aliases":["GHSA-h9jm-ppr9-845g","UBUNTU-CVE-2020-36657"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Gentoo uptimed","requires_auth":"low_privilege","summary":"Local attackers with uptimed account access can gain root privileges via hard link attacks due to unsafe chown operations in uptimed.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"uptimed","vendor":"uptimed_project"}],"cvss":{"score":7.8,"severity":"high","source":"cisa-adp","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-59","name":"Improper Link Resolution Before File Access"}],"description":"uptimed before 0.4.6-r1 on Gentoo allows local users (with access to the uptimed user account) to gain root privileges by creating a hard link within the /var/spool/uptimed directory, because there is an unsafe chown -R call.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Privilege escalation in n/a","id":"CVE-2020-36657","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Security feature bypass in n/a","id":"CVE-2020-36658"},"packages":[],"prev":{"headline":"Spectra \u003c 1.15.0 - Contributor+ Stored Cross-Side Scripting","id":"CVE-2020-36656"},"products":["n/a"],"published":"2023-01-25","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":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-04-01","vendors":["n/a"]},"summary":"Local attackers with uptimed account access can gain root privileges via hard link attacks due to unsafe chown operations in uptimed.","url":"https://insights.sbomify.com/CVE-2020-36657/"}
