An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2019-6809 and fix it if it is affected.\n\nWhat it is: CVE-2019-6809 is a high-severity denial of service vulnerability in Schneider Electric SE Modicon M340, published on 17 Sep 2019. 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-2019-6809 in the wild and no public exploit code.\n\nAffected product: Schneider Electric SE Modicon M340. 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-2019-6809/ (Markdown: https://insights.sbomify.com/CVE-2019-6809/index.md)","id":"CVE-2019-6809","markdown":"https://insights.sbomify.com/CVE-2019-6809/index.md","name":"CVE-2019-6809","record":{"aliases":["GHSA-f73x-vrcr-2p7q"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Schneider Electric PLC","requires_auth":"none","summary":"Attackers can cause denial of service on Schneider Electric Modicon PLCs by sending invalid data to the controller.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"schneider","cpe":[{"product":"modicon_m340_firmware","vendor":"schneider-electric"},{"product":"modicon_m580_firmware","vendor":"schneider-electric"},{"product":"modicon_premium_firmware","vendor":"schneider-electric"},{"product":"modicon_quantum_firmware","vendor":"schneider-electric"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-755","name":"Improper Handling of Exceptional Conditions"},{"id":"CWE-248","name":"Uncaught Exception"}],"description":"A CWE-248: Uncaught Exception vulnerability exists in Modicon M580 (firmware versions prior to V2.90), Modicon M340 (firmware versions prior to V3.10), Modicon Premium (all versions), Modicon Quantum (all versions), which could cause a possible denial of service when reading invalid data from the controller.","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 Modicon M340","id":"CVE-2019-6809","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2019"},"n_packages":0,"n_references":1,"next":{"headline":"Missing authorization in BMXNOR0200H Ethernet / Serial RTU module","id":"CVE-2019-6810"},"packages":[],"prev":{"headline":"Missing authorization in Modicon M580 Modicon M340 Modicon Quantum Modicon Premium","id":"CVE-2019-6808"},"products":["Modicon M340","Modicon M580","Modicon Premium","Modicon Quantum"],"published":"2019-09-17","related":[{"cvss_score":9.8,"headline":"Auth bypass in Modicon M580 Modicon M340 Modicon Quantum Modicon Premium","id":"CVE-2018-7842","kev_date_added":null,"published":"2019-05-22"},{"cvss_score":9.8,"headline":"Auth bypass in Modicon M580 Modicon M340 Modicon Quantum Modicon Premium","id":"CVE-2018-7846","kev_date_added":null,"published":"2019-05-22"},{"cvss_score":9.8,"headline":"Missing authorization in Modicon M580 Modicon M340 Modicon Quantum Modicon Premium","id":"CVE-2018-7847","kev_date_added":null,"published":"2019-05-22"},{"cvss_score":9.8,"headline":"Missing authorization in Modicon M580 Modicon M340 Modicon Quantum Modicon Premium","id":"CVE-2019-6808","kev_date_added":null,"published":"2019-05-22"},{"cvss_score":7.5,"headline":"Information disclosure in Modicon M580, Modicon M340, Modicon Premium , Modicon Quantum (all firmware versions)","id":"CVE-2019-6845","kev_date_added":null,"published":"2019-10-29"},{"cvss_score":7.5,"headline":"Information disclosure in Modicon M580, Modicon M340, Modicon Premium , Modicon Quantum (all firmware versions)","id":"CVE-2019-6851","kev_date_added":null,"published":"2019-10-29"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["Schneider Electric SE"]},"summary":"Attackers can cause denial of service on Schneider Electric Modicon PLCs by sending invalid data to the controller.","url":"https://insights.sbomify.com/CVE-2019-6809/"}
