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-2021-25437 in the wild and no public exploit code.\n\nAffected product: Samsung Mobile Tizen wearable devices. 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-2021-25437/ (Markdown: https://insights.sbomify.com/CVE-2021-25437/index.md)","id":"CVE-2021-25437","markdown":"https://insights.sbomify.com/CVE-2021-25437/index.md","name":"CVE-2021-25437","record":{"aliases":["GHSA-36pg-q9f9-m4xv"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Tizen wearable OS","requires_auth":"none","summary":"Attackers can execute arbitrary code on Tizen wearable devices by replacing the FOTA update file due to improper access control.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Samsung Mobile","cpe":[{"product":"tizen","vendor":"linux"}],"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":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Improper access control vulnerability in Tizen FOTA service prior to Firmware update JUL-2021 Release allows attackers to arbitrary code execution by replacing FOTA update file.","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":"Missing authorization in Tizen wearable devices","id":"CVE-2021-25437","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Path traversal in Samsung Members","id":"CVE-2021-25438"},"packages":[],"prev":{"headline":"Code injection in Tizen wearable devices","id":"CVE-2021-25436"},"products":["Tizen wearable devices"],"published":"2021-07-08","related":[{"cvss_score":9.8,"headline":"Code injection in Tizen wearable devices","id":"CVE-2021-25434","kev_date_added":null,"published":"2021-07-08"},{"cvss_score":9.8,"headline":"Code injection in Tizen wearable devices","id":"CVE-2021-25435","kev_date_added":null,"published":"2021-07-08"},{"cvss_score":9.8,"headline":"Code injection in Tizen wearable devices","id":"CVE-2021-25436","kev_date_added":null,"published":"2021-07-08"},{"cvss_score":8.8,"headline":"Privilege escalation in n/a","id":"CVE-2018-16262","kev_date_added":null,"published":"2020-01-22"},{"cvss_score":8.8,"headline":"The PulseAudio system service in Tizen allows an unprivileged process to control its A2DP MediaEndpoint, due to improper D-Bus security policy configurations.","id":"CVE-2018-16263","kev_date_added":null,"published":"2020-01-22"},{"cvss_score":8.1,"headline":"Privilege escalation in n/a","id":"CVE-2018-16266","kev_date_added":null,"published":"2020-01-22"}],"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":"2024-08-03","vendors":["Samsung Mobile"]},"summary":"Attackers can execute arbitrary code on Tizen wearable devices by replacing the FOTA update file due to improper access control.","url":"https://insights.sbomify.com/CVE-2021-25437/"}
