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-2021-37023 in the wild and no public exploit code.\n\nAffected product: Huawei Harmonyos. 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-2021-37023/ (Markdown: https://insights.sbomify.com/CVE-2021-37023/index.md)","id":"CVE-2021-37023","markdown":"https://insights.sbomify.com/CVE-2021-37023/index.md","name":"CVE-2021-37023","record":{"aliases":["GHSA-f2j4-5mw5-qhr4"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Huawei HarmonyOS","requires_auth":"none","summary":"Attackers can read and write media files in non-distributed directories on any networked Huawei HarmonyOS device due to improper access control.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"huawei","cpe":[{"product":"harmonyos","vendor":"huawei"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"There is a Improper Access Control vulnerability in Huawei Smartphone.Successful exploitation of this vulnerability will cause media files which can be reads and writes in non-distributed directories on any device on the network..","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":"Path traversal in HarmonyOS","id":"CVE-2021-37023","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"huawei:harmonyos","products":["huawei:harmonyos"],"type":"path_traversal","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Denial of service in HarmonyOS","id":"CVE-2021-37024"},"packages":[],"prev":{"headline":"Memory corruption in HarmonyOS","id":"CVE-2021-37022"},"products":["HarmonyOS"],"published":"2021-11-23","related":[{"cvss_score":10,"headline":"Memory corruption in HarmonyOS","id":"CVE-2026-34865","kev_date_added":null,"published":"2026-04-13"},{"cvss_score":10,"headline":"Other in HarmonyOS","id":"CVE-2023-34157","kev_date_added":null,"published":"2023-06-16"},{"cvss_score":9.8,"headline":"Denial of service in HarmonyOS","id":"CVE-2023-41294","kev_date_added":null,"published":"2023-09-25"},{"cvss_score":9.8,"headline":"Denial of service in HarmonyOS","id":"CVE-2022-48478","kev_date_added":null,"published":"2023-05-26"},{"cvss_score":9.8,"headline":"Memory corruption in HarmonyOS","id":"CVE-2022-48479","kev_date_added":null,"published":"2023-05-26"},{"cvss_score":9.8,"headline":"Race condition in HarmonyOS","id":"CVE-2022-46316","kev_date_added":null,"published":"2022-12-20"},{"cvss_score":9.8,"headline":"Memory corruption in HarmonyOS","id":"CVE-2022-38980","kev_date_added":null,"published":"2022-10-14"}],"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":"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":["Huawei"]},"summary":"Attackers can read and write media files in non-distributed directories on any networked Huawei HarmonyOS device due to improper access control.","url":"https://insights.sbomify.com/CVE-2021-37023/"}
