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-2025-64734 in the wild and no public exploit code.\n\nAffected product: Gallagher T21 Reader. 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-2025-64734/ (Markdown: https://insights.sbomify.com/CVE-2025-64734/index.md)","id":"CVE-2025-64734","markdown":"https://insights.sbomify.com/CVE-2025-64734/index.md","name":"CVE-2025-64734","record":{"aliases":["GHSA-r4wh-whpg-rc2q"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Access control reader","requires_auth":"none","summary":"An attacker with physical access can cause a denial of service on the T21 Reader, preventing cardholders from entering the facility.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Gallagher","cpe":[],"cvss":{"score":2.4,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-772","name":"Missing Release of Resource after Effective Lifetime"}],"description":"Missing Release of Resource after Effective Lifetime (CWE-772) in the T21 Reader allows an attacker with physical access to the Reader to perform a denial-of-service attack against that specific reader, preventing cardholders from badging for entry. \n\nThis issue affects Command Centre Server: \n\n9.30 prior to vCR9.30.251028a (distributed in 9.30.2881 (MR3)), 9.20 prior to vCR9.20.251028a (distributed in 9.20.3265 (MR5)), 9.10 prior to vCR9.10.251028a (distributed in 9.10.4135 (MR8)),  all versions of 9.00 and prior.","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":"Denial of service in T21 Reader","id":"CVE-2025-64734","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Information disclosure in Affinity","id":"CVE-2025-64735"},"packages":[],"prev":{"headline":"Information disclosure in Affinity","id":"CVE-2025-64733"},"products":["T21 Reader"],"published":"2025-11-18","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":"partial"},"state":"PUBLISHED","updated":"2025-11-19","vendors":["Gallagher"]},"summary":"An attacker with physical access can cause a denial of service on the T21 Reader, preventing cardholders from entering the facility.","url":"https://insights.sbomify.com/CVE-2025-64734/"}
