An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2025-10259 and fix it if it is affected.\n\nWhat it is: CVE-2025-10259 is a medium-severity denial of service vulnerability in Mitsubishi Electric Corporation MELSEC iQ-F Series FX5S-30MR/DS, published on 6 Nov 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-2025-10259 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-2025-10259/ (Markdown: https://insights.sbomify.com/CVE-2025-10259/index.md)","id":"CVE-2025-10259","markdown":"https://insights.sbomify.com/CVE-2025-10259/index.md","name":"CVE-2025-10259","record":{"aliases":["GHSA-8pxf-65qh-4qrc"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Mitsubishi PLC CPU","requires_auth":"none","summary":"Remote attackers can cause a denial-of-service condition on Mitsubishi MELSEC iQ-F CPU modules by sending crafted TCP packets, disrupting specific connections.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mitsubishi","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-1284","name":"Improper Validation of Specified Quantity in Input"}],"description":"Improper Validation of Specified Quantity in Input vulnerability in TCP Communication Function on Mitsubishi Electric Corporation MELSEC iQ-F Series CPU module allows a remote attacker to disconnect the connection by sending specially crafted TCP packets to cause a denial-of-service (DoS) condition on the products.
