An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-7502 and fix it if it is affected.\n\nWhat it is: CVE-2020-7502 is a high-severity memory corruption vulnerability in Modicon M218 Logic Controller (Firmware version 4.3 and prior), published on 16 Jun 2020. 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-2020-7502 in the wild and no public exploit code.\n\nAffected product: Modicon M218 Logic Controller (Firmware version 4.3 and prior). 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-2020-7502/ (Markdown: https://insights.sbomify.com/CVE-2020-7502/index.md)","id":"CVE-2020-7502","markdown":"https://insights.sbomify.com/CVE-2020-7502/index.md","name":"CVE-2020-7502","record":{"aliases":["GHSA-x4fw-v2f8-f3pj"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Modicon M218 Logic Controller","requires_auth":"none","summary":"An out-of-bounds write vulnerability in the Modicon M218 Logic Controller allows attackers to cause a denial of service via crafted TCP/IP packets.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"schneider","cpe":[{"product":"modicon_m218_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-787","name":"Out-of-bounds Write"}],"description":"A CWE-787: Out-of-bounds Write vulnerability exists in Modicon M218 Logic Controller (Firmware version 4.3 and prior), which may cause a Denial of Service when specific TCP/IP crafted packets are sent to the Modicon M218 Logic 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":"Memory corruption in Modicon M218 Logic Controller (Firmware version 4.3 and prior)","id":"CVE-2020-7502","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Cross-site request forgery in Easergy T300 (Firmware version 1.5.2 and older)","id":"CVE-2020-7503"},"packages":[],"prev":{"headline":"Hardcoded credentials in Vijeo Designer Basic (V1.1 HotFix 16 and prior) and Vijeo Designer (V6.2 SP9 and prior)","id":"CVE-2020-7501"},"products":["Modicon M218 Logic Controller (Firmware version 4.3 and prior)"],"published":"2020-06-16","related":[{"cvss_score":7.5,"headline":"Denial of service in Modicon M218 Logic Controller (V5.1.0.6 and prior)","id":"CVE-2021-22800","kev_date_added":null,"published":"2022-02-11"},{"cvss_score":7.5,"headline":"Memory corruption in Modicon M218 Logic Controller V5.0.0.7 and prior","id":"CVE-2020-7524","kev_date_added":null,"published":"2020-08-31"}],"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":"An out-of-bounds write vulnerability in the Modicon M218 Logic Controller allows attackers to cause a denial of service via crafted TCP/IP packets.","url":"https://insights.sbomify.com/CVE-2020-7502/"}
