An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-4020 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-2020-4020/ (Markdown: https://insights.sbomify.com/CVE-2020-4020/index.md)","id":"CVE-2020-4020","markdown":"https://insights.sbomify.com/CVE-2020-4020/index.md","name":"CVE-2020-4020","record":{"aliases":["GHSA-72w5-xxp4-hp3g"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Atlassian Companion App","requires_auth":"high_privilege","summary":"Remote attackers controlling a connected Confluence Server can execute arbitrary executables on the Atlassian Companion App due to protection mechanism failure.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"atlassian","cpe":[{"product":"companion","vendor":"atlassian"}],"cvss":{"score":7.2,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"The file downloading functionality in the Atlassian Companion App before version 1.0.0 allows remote attackers, who control a Confluence Server instance that the Companion App is connected to, execute arbitrary .exe files via a Protection Mechanism Failure.","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":"Code injection in Companion App","id":"CVE-2020-4020","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Cross-site scripting in Jira Server and Data Center","id":"CVE-2020-4021"},"packages":[],"prev":{"headline":"Path traversal in Companion App","id":"CVE-2020-4019"},"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":7.8,"headline":"Path traversal in Companion App","id":"CVE-2020-4019","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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-16","vendors":["Atlassian"]},"summary":"Remote attackers controlling a connected Confluence Server can execute arbitrary executables on the Atlassian Companion App due to protection mechanism failure.","url":"https://insights.sbomify.com/CVE-2020-4020/"}
