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-2020-27534 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/docker/docker (Go): affected all versions; fixed in 19.03.9\n- github.com/docker/docker (Go): affected all versions; fixed in 19.03.9\n- github.com/moby/moby (Go): affected all versions; fixed in 19.03.9\n- github.com/moby/moby (Go): affected all versions; fixed in 19.03.9\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-2020-27534/ (Markdown: https://insights.sbomify.com/CVE-2020-27534/index.md)","id":"CVE-2020-27534","markdown":"https://insights.sbomify.com/CVE-2020-27534/index.md","name":"CVE-2020-27534","record":{"aliases":["GHSA-6hwg-w5jg-9c6x"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Docker Engine","requires_auth":"none","summary":"Docker Engine allows local attackers to execute arbitrary code or escalate privileges via path traversal in binfmt_misc checks.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"docker","vendor":"docker"}],"cvss":{"score":5.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"util/binfmt_misc/check.go in Builder in Docker Engine before 19.03.9 calls os.OpenFile with a potentially unsafe qemu-check temporary pathname, constructed with an empty first argument in an ioutil.TempDir call.","ecosystems":["Go"],"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":"Path Traversal in Moby builder","id":"CVE-2020-27534","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"path_traversal","year":"2020"},"n_packages":4,"n_references":5,"next":{"headline":"Memory corruption in n/a","id":"CVE-2020-27539"},"packages":[{"ecosystem":"Go","fixed":["19.03.9"],"introduced":["0"],"last_affected":[],"package":"github.com/docker/docker","purl":null,"source":"GHSA-6hwg-w5jg-9c6x"},{"ecosystem":"Go","fixed":["19.03.9"],"introduced":["0"],"last_affected":[],"package":"github.com/docker/docker","purl":"pkg:golang/github.com/docker/docker","source":"GHSA-6hwg-w5jg-9c6x"},{"ecosystem":"Go","fixed":["19.03.9"],"introduced":["0"],"last_affected":[],"package":"github.com/moby/moby","purl":null,"source":"GHSA-6hwg-w5jg-9c6x"},{"ecosystem":"Go","fixed":["19.03.9"],"introduced":["0"],"last_affected":[],"package":"github.com/moby/moby","purl":"pkg:golang/github.com/moby/moby","source":"GHSA-6hwg-w5jg-9c6x"}],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-27533"},"products":["n/a"],"published":"2020-12-30","related":[{"cvss_score":10,"headline":"Arbitrary Code Execution","id":"CVE-2014-9357","kev_date_added":null,"published":"2014-12-16"},{"cvss_score":8.8,"headline":"Privilege escalation in Docker","id":"CVE-2020-14298","kev_date_added":null,"published":"2020-07-13"},{"cvss_score":8.8,"headline":"Privilege escalation in Docker","id":"CVE-2020-14300","kev_date_added":null,"published":"2020-07-13"},{"cvss_score":8.8,"headline":"Deserialization in n/a","id":"CVE-2018-15514","kev_date_added":null,"published":"2018-09-01"},{"cvss_score":8.6,"headline":"Path Traversal in Docker","id":"CVE-2014-9356","kev_date_added":null,"published":"2019-12-02"},{"cvss_score":8.4,"headline":"Command injection in n/a","id":"CVE-2019-13139","kev_date_added":null,"published":"2019-08-22"},{"cvss_score":8.1,"headline":"Other in n/a","id":"CVE-2014-5282","kev_date_added":null,"published":"2018-02-06"}],"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":"Docker Engine allows local attackers to execute arbitrary code or escalate privileges via path traversal in binfmt_misc checks.","url":"https://insights.sbomify.com/CVE-2020-27534/"}
