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-2023-27921 in the wild and no public exploit code.\n\nAffected product: JINS MEME CORE. 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-2023-27921/ (Markdown: https://insights.sbomify.com/CVE-2023-27921/index.md)","id":"CVE-2023-27921","markdown":"https://insights.sbomify.com/CVE-2023-27921/index.md","name":"CVE-2023-27921","record":{"aliases":["GHSA-2c74-2hh4-g45r"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Smart glasses firmware","requires_auth":"none","summary":"A network-adjacent attacker can decrypt sensor data from JINS MEME CORE devices due to a hard-coded cryptographic key in the firmware.","user_interaction":"not_required","vuln_class":"hardcoded_credentials"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"jins_meme_firmware","vendor":"jins"}],"cvss":{"score":6.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-798","name":"Use of Hard-coded Credentials"}],"description":"JINS MEME CORE Firmware version 2.2.0 and earlier uses a hard-coded cryptographic key, which may lead to data acquired by a sensor of the affected product being decrypted by a network-adjacent attacker.","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":"Hardcoded credentials in JINS MEME CORE","id":"CVE-2023-27921","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"hardcoded_credentials","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site scripting in Newsletter","id":"CVE-2023-27922"},"packages":[],"prev":{"headline":"Missing authorization in SolarView Compact","id":"CVE-2023-27920"},"products":["JINS MEME CORE"],"published":"2023-05-23","related":[],"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":"2025-01-31","vendors":["JINS Inc."]},"summary":"A network-adjacent attacker can decrypt sensor data from JINS MEME CORE devices due to a hard-coded cryptographic key in the firmware.","url":"https://insights.sbomify.com/CVE-2023-27921/"}
