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-2020-27252 in the wild and no public exploit code.\n\nAffected product: Medtronic Smart Model 25000 Patient Reader. 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-2020-27252/ (Markdown: https://insights.sbomify.com/CVE-2020-27252/index.md)","id":"CVE-2020-27252","markdown":"https://insights.sbomify.com/CVE-2020-27252/index.md","name":"CVE-2020-27252","record":{"aliases":["GHSA-qmhj-wg3r-x2h5"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Medtronic Patient Reader","requires_auth":"none","summary":"A race condition in the software update system allows attackers to upload and execute unsigned firmware, gaining remote control of the Medtronic MyCareLink Smart Patient Reader.","user_interaction":"required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"mycarelink_smart_model_25000_firmware","vendor":"medtronic"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-367","name":"Time-of-check Time-of-use (TOCTOU) Race Condition"}],"description":"Medtronic MyCareLink Smart 25000 is \n\nvulnerable to a race condition in the MCL Smart Patient Reader software update system, which allows unsigned firmware to be uploaded and executed on the Patient Reader.
