Multiple MFPs, published on 29 Jan 2026. 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-2025-53869 in the wild and no public exploit code.\n\nAffected product: Brother Industries, Ltd. Multiple MFPs. 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-2025-53869/ (Markdown: https://insights.sbomify.com/CVE-2025-53869/index.md)","id":"CVE-2025-53869","markdown":"https://insights.sbomify.com/CVE-2025-53869/index.md","name":"CVE-2025-53869","record":{"aliases":["GHSA-wrgj-7835-qfh2"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Multifunction printers","requires_auth":"none","summary":"Man-in-the-middle attackers can replace root certificates due to improper validation, bypassing security features on Brother, Konica Minolta, and Ricoh MFPs.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"Multiple MFPs provided by Brother Industries, Ltd. does not properly validate server certificates, which may allow a man-in-the-middle attacker to replace the set of root certificates used by the product with a set of arbitrary certificates.","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":"Security feature bypass in Multiple MFPs","id":"CVE-2025-53869","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2025"},"n_packages":0,"n_references":4,"next":{"headline":"Command injection in FortiAP","id":"CVE-2025-53870"},"packages":[],"prev":{"headline":"BIG-IP SCP and SFTP vulnerability","id":"CVE-2025-53868"},"products":["Multiple MFPs"],"published":"2026-01-29","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":"2026-01-29","vendors":["Brother Industries, Ltd.","Konica Minolta, Inc.","Ricoh Company, Ltd."]},"summary":"Man-in-the-middle attackers can replace root certificates due to improper validation, bypassing security features on Brother, Konica Minolta, and Ricoh MFPs.","url":"https://insights.sbomify.com/CVE-2025-53869/"}
