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-2021-40053 in the wild and no public exploit code.\n\nAffected product: Huawei Emui. 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-2021-40053/ (Markdown: https://insights.sbomify.com/CVE-2021-40053/index.md)","id":"CVE-2021-40053","markdown":"https://insights.sbomify.com/CVE-2021-40053/index.md","name":"CVE-2021-40053","record":{"aliases":["GHSA-6465-pr9x-552x"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Huawei HarmonyOS","requires_auth":"none","summary":"Attackers can exploit permission control flaws in the Nearby module to compromise system availability and data integrity.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"huawei","cpe":[{"product":"emui","vendor":"huawei"},{"product":"harmonyos","vendor":"huawei"},{"product":"magic_ui","vendor":"huawei"}],"cvss":{"score":9.1,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-276","name":"Incorrect Default Permissions"}],"description":"There is a permission control vulnerability in the Nearby module.Successful exploitation of this vulnerability will affect availability and integrity.","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 HarmonyOS;EMUI;Magic UI","id":"CVE-2021-40053","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"huawei:emui","products":["huawei:emui","huawei:harmonyos","huawei:magic_ui"],"type":"missing_authorization","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Integer overflow in EMUI","id":"CVE-2021-40054"},"packages":[],"prev":{"headline":"Integer overflow in EMUI","id":"CVE-2021-40052"},"products":["HarmonyOS;EMUI;Magic UI"],"published":"2022-03-07","related":[{"cvss_score":9.8,"headline":"Memory corruption in EMUI","id":"CVE-2023-52370","kev_date_added":null,"published":"2024-02-18"},{"cvss_score":9.8,"headline":"Business logic in EMUI","id":"CVE-2023-52378","kev_date_added":null,"published":"2024-02-18"},{"cvss_score":9.8,"headline":"Code injection in EMUI","id":"CVE-2023-52381","kev_date_added":null,"published":"2024-02-18"},{"cvss_score":9.8,"headline":"Memory corruption in EMUI","id":"CVE-2023-52103","kev_date_added":null,"published":"2024-01-16"},{"cvss_score":9.8,"headline":"Privilege escalation in EMUI","id":"CVE-2023-46773","kev_date_added":null,"published":"2023-12-06"},{"cvss_score":9.8,"headline":"Privilege escalation in EMUI","id":"CVE-2023-44105","kev_date_added":null,"published":"2023-10-11"},{"cvss_score":9.8,"headline":"Privilege escalation in EMUI","id":"CVE-2023-44106","kev_date_added":null,"published":"2023-10-11"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can exploit permission control flaws in the Nearby module to compromise system availability and data integrity.","url":"https://insights.sbomify.com/CVE-2021-40053/"}
