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-2020-12856 in the wild and no public exploit code.\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-2020-12856/ (Markdown: https://insights.sbomify.com/CVE-2020-12856/index.md)","id":"CVE-2020-12856","markdown":"https://insights.sbomify.com/CVE-2020-12856/index.md","name":"CVE-2020-12856","record":{"aliases":["A-157038281","ASB-A-157038281","GHSA-9q2w-3c47-gq6j"],"analysis":{"component_type":"mobile_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Contact tracing app","requires_auth":"none","summary":"Remote attackers can re-identify users over time via Bluetooth in contact tracing apps, compromising user privacy.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"abtracetogether","vendor":"alberta"},{"product":"covidsafe","vendor":"health"},{"product":"tracetogether","vendor":"tracetogether"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"OpenTrace, as used in COVIDSafe through v1.0.17, TraceTogether, ABTraceTogether, and other applications on iOS and Android, allows remote attackers to conduct long-term re-identification attacks and possibly have unspecified other impact, because of how Bluetooth is used.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2020-05-15","github_poc":1,"max_poc_stars":25,"metasploit":0,"nuclei":0,"refs":[{"date":"2020-05-15T00:18:03Z","kind":"github_poc","ref":"https://github.com/alwentiu/COVIDSafe-CVE-2020-12856","stars":25,"title":"A bluetooth-related vulnerability in some contact tracing apps"}],"tier":"poc_unverified"},"has_fix":true,"headline":"Information disclosure in n/a","id":"CVE-2020-12856","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2020"},"n_packages":0,"n_references":3,"next":{"headline":"Information disclosure in n/a","id":"CVE-2020-12857"},"packages":[],"prev":{"headline":"Open redirect in n/a","id":"CVE-2020-12855"},"products":["n/a"],"published":"2020-05-18","related":[{"cvss_score":6.5,"headline":"Denial of service in n/a","id":"CVE-2020-12717","kev_date_added":null,"published":"2020-05-14"}],"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Remote attackers can re-identify users over time via Bluetooth in contact tracing apps, compromising user privacy.","url":"https://insights.sbomify.com/CVE-2020-12856/"}
