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-2023-21455 in the wild and no public exploit code.\n\nAffected product: Samsung Mobile 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-2023-21455/ (Markdown: https://insights.sbomify.com/CVE-2023-21455/index.md)","id":"CVE-2023-21455","markdown":"https://insights.sbomify.com/CVE-2023-21455/index.md","name":"CVE-2023-21455","record":{"aliases":["GHSA-wxhm-9fww-9xcx"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Samsung mobile devices","requires_auth":"none","summary":"Improper authorization in Exynos baseband allows incorrect handling of unencrypted messages, potentially bypassing security checks on Samsung mobile devices.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Samsung Mobile","cpe":[{"product":"exynos_firmware","vendor":"samsung"}],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:L/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"Improper authorization implementation in Exynos baseband prior to SMR Mar-2023 Release 1 allows incorrect handling of unencrypted message.","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":"Auth bypass in Samsung Mobile Devices","id":"CVE-2023-21455","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Path traversal in Samsung Mobile Devices","id":"CVE-2023-21456"},"packages":[],"prev":{"headline":"Missing authorization in Samsung Mobile Devices","id":"CVE-2023-21454"},"products":["Samsung Mobile Devices"],"published":"2023-03-16","related":[{"cvss_score":6.5,"headline":"Auth bypass in Samsung Mobile Devices","id":"CVE-2022-39901","kev_date_added":null,"published":"2022-12-08"},{"cvss_score":6.5,"headline":"Information disclosure in Samsung Mobile Devices","id":"CVE-2022-39902","kev_date_added":null,"published":"2022-12-08"},{"cvss_score":5.3,"headline":"Information disclosure in Samsung Mobile Devices","id":"CVE-2022-39881","kev_date_added":null,"published":"2022-11-09"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-02-26","vendors":["Samsung Mobile"]},"summary":"Improper authorization in Exynos baseband allows incorrect handling of unencrypted messages, potentially bypassing security checks on Samsung mobile devices.","url":"https://insights.sbomify.com/CVE-2023-21455/"}
