An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2025-7731 and fix it if it is affected.\n\nWhat it is: CVE-2025-7731 is a high-severity vulnerability in Mitsubishi Electric Corporation MELSEC iQ-F Series FX5S-30MR/DS, published on 1 Sep 2025. 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-2025-7731 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-2025-7731/ (Markdown: https://insights.sbomify.com/CVE-2025-7731/index.md)","id":"CVE-2025-7731","markdown":"https://insights.sbomify.com/CVE-2025-7731/index.md","name":"CVE-2025-7731","record":{"aliases":[],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["data_read","data_modify","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Mitsubishi PLC CPU","requires_auth":"none","summary":"Remote attackers can intercept cleartext SLMP messages to steal credentials, allowing them to read/write device values and stop program operations.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mitsubishi","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-319","name":"Cleartext Transmission of Sensitive Information"}],"description":"Cleartext Transmission of Sensitive Information vulnerability in Mitsubishi Electric Corporation MELSEC iQ-F Series CPU module allows a remote unauthenticated attacker to obtain credential information by intercepting SLMP communication messages, and read or write the device values of the product and stop the operations of programs by using the obtained credential information.","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":"Information Disclosure Vulnerability in MELSEC iQ-F Series CPU module","id":"CVE-2025-7731","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2025"},"n_packages":0,"n_references":3,"next":{"headline":"Cross-site scripting in Lazy Load for Videos","id":"CVE-2025-7732"},"packages":[],"prev":{"headline":"Bold Page Builder \u003c= 5.4.5 -
