It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-35954 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-2021-35954/ (Markdown: https://insights.sbomify.com/CVE-2021-35954/index.md)","id":"CVE-2021-35954","markdown":"https://insights.sbomify.com/CVE-2021-35954/index.md","name":"CVE-2021-35954","record":{"aliases":["GHSA-wh39-w6w2-hmvf"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Activity Tracker","requires_auth":"none","summary":"Physically proximate attackers can dump firmware, flash malicious code, or brick the device via the Serial Wire Debug interface.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"reflex_2.0_firmware","vendor":"fastrack"}],"cvss":{"score":8.1,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[],"description":"fastrack Reflex 2.0 W307S_REFLEX_v90.89 Activity Tracker allows physically proximate attackers to dump the firmware, flash custom malicious firmware, and brick the device via the Serial Wire Debug (SWD) feature.","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":"Security feature bypass in n/a","id":"CVE-2021-35954","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Cross site scripting via HTML attributes in the back end","id":"CVE-2021-35955"},"packages":[],"prev":{"headline":"fastrack Reflex 2.0 W307S_REFLEX_v90.89 Activity Tracker allows a Remote attacker to cause a Denial of Service (device outage) via crafted c","id":"CVE-2021-35953"},"products":["n/a"],"published":"2022-12-26","related":[{"cvss_score":7.5,"headline":"fastrack Reflex 2.0 W307S_REFLEX_v90.89 Activity Tracker allows an Unauthenticated Remote attacker to send a malicious firmware update via B","id":"CVE-2021-35951","kev_date_added":null,"published":"2022-12-26"},{"cvss_score":7.5,"headline":"fastrack Reflex 2.0 W307S_REFLEX_v90.89 Activity Tracker allows a Remote attacker to cause a Denial of Service (device outage) via crafted c","id":"CVE-2021-35953","kev_date_added":null,"published":"2022-12-26"},{"cvss_score":5.3,"headline":"fastrack Reflex 2.0 W307S_REFLEX_v90.89 Activity Tracker allows a Remote attacker to change the time, date, and month via Bluetooth LE Chara","id":"CVE-2021-35952","kev_date_added":null,"published":"2022-12-26"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-04-14","vendors":["n/a"]},"summary":"Physically proximate attackers can dump firmware, flash malicious code, or brick the device via the Serial Wire Debug interface.","url":"https://insights.sbomify.com/CVE-2021-35954/"}
