An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2019-6848 and fix it if it is affected.\n\nWhat it is: CVE-2019-6848 is a high-severity denial of service vulnerability in Modicon M580 CPU (BMEx58*) and Modicon M580 communication module (BMENOC0311, BMENOC0321) (see notification for version info), published on 29 Oct 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-2019-6848 in the wild and no public exploit code.\n\nAffected product: Modicon M580 CPU (BMEx58*) and Modicon M580 communication module (BMENOC0311, BMENOC0321) (see notification for version info). 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-2019-6848/ (Markdown: https://insights.sbomify.com/CVE-2019-6848/index.md)","id":"CVE-2019-6848","markdown":"https://insights.sbomify.com/CVE-2019-6848/index.md","name":"CVE-2019-6848","record":{"aliases":["GHSA-gj96-2265-wv5x"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Modicon PLC","requires_auth":"none","summary":"Attackers can cause a Denial of Service on Modicon M580 PLCs by sending specific data to the REST API, impacting industrial control operations.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"schneider","cpe":[{"product":"modicon_bmenoc_0311_firmware","vendor":"schneider-electric"},{"product":"modicon_bmenoc_0321_firmware","vendor":"schneider-electric"},{"product":"modicon_m580_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-755","name":"Improper Handling of Exceptional Conditions"}],"description":"A CWE-755: Improper Handling of Exceptional Conditions vulnerability exists in Modicon M580 CPU (BMEx58*) and Modicon M580 communication module (BMENOC0311, BMENOC0321) (see notification for version info), which could cause a Denial of Service attack on the PLC when sending specific data on the REST API of the controller/communication module.","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 M580 CPU (BMEx58*) and Modicon M580 communication module (BMENOC0311, BMENOC0321) (see notification for version info)","id":"CVE-2019-6848","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":"Information disclosure in Modicon M580, Modicon BMENOC 0311, Modicon BMENOC 0321","id":"CVE-2019-6849"},"packages":[],"prev":{"headline":"Denial of service in Modicon M580, Modicon M340, and Modicon BMxCRA / 140CRA modules (see notification for version info)","id":"CVE-2019-6847"},"products":["Modicon M580 CPU (BMEx58*) and Modicon M580 communication module (BMENOC0311, BMENOC0321) (see notification for version info)"],"published":"2019-10-29","related":[{"cvss_score":7.5,"headline":"Information disclosure in Modicon M580, Modicon BMENOC 0311, Modicon BMENOC 0321","id":"CVE-2019-6849","kev_date_added":null,"published":"2019-10-29"},{"cvss_score":7.5,"headline":"Information disclosure in Modicon M580, Modicon BMENOC 0311, Modicon BMENOC 0321","id":"CVE-2019-6850","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":["n/a"]},"summary":"Attackers can cause a Denial of Service on Modicon M580 PLCs by sending specific data to the REST API, impacting industrial control operations.","url":"https://insights.sbomify.com/CVE-2019-6848/"}
