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-2025-7405 in the wild and no public exploit code.\n\nAffected product: Mitsubishi Electric Corporation MELSEC iQ-F Series FX5S-30MR/DS. 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-2025-7405/ (Markdown: https://insights.sbomify.com/CVE-2025-7405/index.md)","id":"CVE-2025-7405","markdown":"https://insights.sbomify.com/CVE-2025-7405/index.md","name":"CVE-2025-7405","record":{"aliases":[],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["data_read","data_modify","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Mitsubishi PLC","requires_auth":"none","summary":"Remote attackers can read, modify, or stop PLC operations due to missing authentication in MODBUS/TCP, impacting industrial control systems.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mitsubishi","cpe":[],"cvss":{"score":7.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"Missing Authentication for Critical Function vulnerability in Mitsubishi Electric Corporation MELSEC iQ-F Series CPU module allows a remote unauthenticated attacker to read or write the device values of the product and stop the operation of the programs, since MODBUS/TCP in the products does not have authentication features.","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":"Missing authorization in MELSEC iQ-F Series FX5S-30MR/DS","id":"CVE-2025-7405","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2025"},"n_packages":0,"n_references":3,"next":{"headline":"A Sudo Privilege Escalation Vulnerability in Nokia MantaRay NM","id":"CVE-2025-7406"},"packages":[],"prev":{"headline":"Calibre Web 0.6.24 \u0026 Autocaliweb 0.7.0 -
