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-2021-25378 in the wild and no public exploit code.\n\nAffected product: Samsung Mobile SmartThings. 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-2021-25378/ (Markdown: https://insights.sbomify.com/CVE-2021-25378/index.md)","id":"CVE-2021-25378","markdown":"https://insights.sbomify.com/CVE-2021-25378/index.md","name":"CVE-2021-25378","record":{"aliases":["GHSA-j677-7992-mrpc"],"analysis":{"component_type":"mobile_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"SmartThings mobile app","requires_auth":"none","summary":"Remote attackers can cause temporary denial of service in the SmartThings mobile application due to improper access control on a specific port.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Samsung Mobile","cpe":[{"product":"smartthings","vendor":"samsung"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Improper access control of certain port in SmartThings prior to version 1.7.63.6 allows remote temporary denial of service.","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":"Denial of service in SmartThings","id":"CVE-2021-25378","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Other in Gallery","id":"CVE-2021-25379"},"packages":[],"prev":{"headline":"Privilege escalation in Samsung Experience Service","id":"CVE-2021-25377"},"products":["SmartThings"],"published":"2021-04-09","related":[{"cvss_score":8.8,"headline":"Samsung SmartThings Improper Verification of Cryptographic Signature Authentication Bypass Vulnerability","id":"CVE-2025-2233","kev_date_added":null,"published":"2025-03-11"},{"cvss_score":7.5,"headline":"Missing authorization in Smart Things","id":"CVE-2022-30746","kev_date_added":null,"published":"2022-06-07"},{"cvss_score":5.9,"headline":"Auth bypass in SmartThings","id":"CVE-2024-34596","kev_date_added":null,"published":"2024-07-02"},{"cvss_score":5.9,"headline":"Missing authorization in SmartThings","id":"CVE-2024-20852","kev_date_added":null,"published":"2024-04-02"},{"cvss_score":5.5,"headline":"Missing authorization in Smart Things","id":"CVE-2022-30747","kev_date_added":null,"published":"2022-06-07"},{"cvss_score":5.3,"headline":"Privilege escalation in SmartThings","id":"CVE-2021-25508","kev_date_added":null,"published":"2021-11-05"}],"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":"Remote attackers can cause temporary denial of service in the SmartThings mobile application due to improper access control on a specific port.","url":"https://insights.sbomify.com/CVE-2021-25378/"}
