It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-4019 in the wild and no public exploit code.\n\nAffected product: Atlassian Companion App. 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-2020-4019/ (Markdown: https://insights.sbomify.com/CVE-2020-4019/index.md)","id":"CVE-2020-4019","markdown":"https://insights.sbomify.com/CVE-2020-4019/index.md","name":"CVE-2020-4019","record":{"aliases":["GHSA-vcrx-86h7-q9f8"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Atlassian Companion App","requires_auth":"none","summary":"Local attackers can execute arbitrary code by exploiting an untrusted search path vulnerability in the file editing functionality.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"atlassian","cpe":[{"product":"companion","vendor":"atlassian"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-426","name":"Untrusted Search Path"}],"description":"The file editing functionality in the Atlassian Companion App before version 1.0.0 allows local attackers to have the app run a different executable in place of the app's cmd.exe via a untrusted search path vulnerability.","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":"Path traversal in Companion App","id":"CVE-2020-4019","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Code injection in Companion App","id":"CVE-2020-4020"},"packages":[],"prev":{"headline":"Cross-site request forgery in Crucible","id":"CVE-2020-4018"},"products":["Companion App"],"published":"2020-06-01","related":[{"cvss_score":9.6,"headline":"Security feature bypass in Companion for Mac","id":"CVE-2023-22524","kev_date_added":null,"published":"2023-12-06"},{"cvss_score":7.2,"headline":"Code injection in Companion App","id":"CVE-2020-4020","kev_date_added":null,"published":"2020-06-01"}],"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":"2024-09-16","vendors":["Atlassian"]},"summary":"Local attackers can execute arbitrary code by exploiting an untrusted search path vulnerability in the file editing functionality.","url":"https://insights.sbomify.com/CVE-2020-4019/"}
