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-2025-4053 in the wild and no public exploit code.\n\nAffected product: Be-Tech Mifare Classic cards. 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-2025-4053/ (Markdown: https://insights.sbomify.com/CVE-2025-4053/index.md)","id":"CVE-2025-4053","markdown":"https://insights.sbomify.com/CVE-2025-4053/index.md","name":"CVE-2025-4053","record":{"aliases":["GHSA-cg49-x3j6-7j3g"],"analysis":{"component_type":"iot_embedded","fix_type":"end_of_life","impacts":["privilege_escalation","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Hotel access control","requires_auth":"low_privilege","summary":"Attackers with a guest card can create a master key to unlock all building locks due to cleartext storage, requiring full system replacement.","user_interaction":"not_required","vuln_class":"hardcoded_credentials"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERT-PL","cpe":[],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:P/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-312","name":"Cleartext Storage of Sensitive Information"}],"description":"The data stored in Be-Tech Mifare Classic card is stored in cleartext. An attacker having access to a Be-Tech hotel guest Mifare Classic card can create a master key card that unlocks all the locks in the building. \n\nThis issue affects all Be-Tech Mifare Classic card systems. To fix the vulnerability, it is necessary to replace the software, encoder, cards, and PCBs in the locks.","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":"Unauthorized creation of master key in Mifare Classic Be-Tech cards","id":"CVE-2025-4053","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"hardcoded_credentials","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Relevanssi \u003c= 4.24.3 (Free) and \u003c= 2.27.4 (Premium) - Unauthenticated Stored Cross-Site Scripting via Search Highlights","id":"CVE-2025-4054"},"packages":[],"prev":{"headline":"Security feature bypass in Chrome","id":"CVE-2025-4052"},"products":["Mifare Classic cards"],"published":"2025-05-26","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"total"},"state":"PUBLISHED","updated":"2025-05-27","vendors":["Be-Tech"]},"summary":"Attackers with a guest card can create a master key to unlock all building locks due to cleartext storage, requiring full system replacement.","url":"https://insights.sbomify.com/CVE-2025-4053/"}
