An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2019-6831 and fix it if it is affected.\n\nWhat it is: CVE-2019-6831 is a high-severity denial of service vulnerability in Schneider Electric SE BMXNOR0200H Ethernet / Serial RTU module, 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-2019-6831 in the wild and no public exploit code.\n\nAffected product: Schneider Electric SE BMXNOR0200H Ethernet / Serial RTU module. 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-2019-6831/ (Markdown: https://insights.sbomify.com/CVE-2019-6831/index.md)","id":"CVE-2019-6831","markdown":"https://insights.sbomify.com/CVE-2019-6831/index.md","name":"CVE-2019-6831","record":{"aliases":["GHSA-gvw6-phvj-chmf"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial RTU module","requires_auth":"none","summary":"An attacker can cause disconnection of active connections in Schneider Electric RTU modules by sending a high volume of IEC 60870-5-104 packets.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"schneider","cpe":[{"product":"bmxnor0200h_firmware","vendor":"schneider-electric"}],"cvss":{"score":8.6,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-754","name":"Improper Check for Unusual or Exceptional Conditions"}],"description":"A CWE-754: Improper Check for Unusual or Exceptional Conditions vulnerability exists in BMXNOR0200H Ethernet / Serial RTU module (all firmware versions), which could cause disconnection of active connections when an unusually high number of IEC 60870- 5-104 packets are received by the module on port 2404/TCP.","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 BMXNOR0200H Ethernet / Serial RTU module","id":"CVE-2019-6831","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2019"},"n_packages":0,"n_references":2,"next":{"headline":"Auth bypass in Wiser for KNX","id":"CVE-2019-6832"},"packages":[],"prev":{"headline":"Denial of service in Modicon M580","id":"CVE-2019-6830"},"products":["BMXNOR0200H Ethernet / Serial RTU module"],"published":"2019-09-17","related":[{"cvss_score":8.8,"headline":"Missing authorization in BMXNOR0200H Ethernet / Serial RTU module","id":"CVE-2019-6810","kev_date_added":null,"published":"2019-09-17"},{"cvss_score":7.5,"headline":"Denial of service in BMXNOR0200H Ethernet / Serial RTU module","id":"CVE-2019-6813","kev_date_added":null,"published":"2019-09-17"}],"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":"An attacker can cause disconnection of active connections in Schneider Electric RTU modules by sending a high volume of IEC 60870-5-104 packets.","url":"https://insights.sbomify.com/CVE-2019-6831/"}
