It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-7568 and fix it if it is affected.\n\nWhat it is: CVE-2020-7568 is a low-severity vulnerability in Modicon M221, all references, all versions, published on 19 Nov 2020. It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-7568 in the wild and no public exploit code.\n\nAffected product: Modicon M221, all references, all versions. 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-2020-7568/ (Markdown: https://insights.sbomify.com/CVE-2020-7568/index.md)","id":"CVE-2020-7568","markdown":"https://insights.sbomify.com/CVE-2020-7568/index.md","name":"CVE-2020-7568","record":{"aliases":["GHSA-45cc-9wgf-p2qq"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Modicon PLC","requires_auth":"none","summary":"Attackers can capture network traffic to disclose non-sensitive information from Modicon M221 controllers communicating with EcoStruxure Machine - Basic software.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"schneider","cpe":[{"product":"modicon_m221_firmware","vendor":"schneider-electric"}],"cvss":{"score":3.1,"severity":"low","source":"cisa-adp","vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"A CWE-200: Exposure of Sensitive Information to an Unauthorized Actor vulnerability exists in Modicon M221 (all references, all versions) that could allow non sensitive information disclosure when the attacker has captured the traffic between EcoStruxure Machine - Basic software and Modicon M221 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":"Information disclosure in Modicon M221, all references, all versions","id":"CVE-2020-7568","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"File upload in EcoStruxure Building Operation WebReports V1.9 - V3.1","id":"CVE-2020-7569"},"packages":[],"prev":{"headline":"Information disclosure in Modicon M221, all references, all versions","id":"CVE-2020-7567"},"products":["Modicon M221, all references, all versions"],"published":"2020-11-19","related":[{"cvss_score":9.8,"headline":"Weak cryptography in Modicon M221 (all references, all versions)","id":"CVE-2020-28214","kev_date_added":null,"published":"2020-12-11"},{"cvss_score":9.8,"headline":"Auth bypass in Modicon M221, all references, all versions prior to firmware V1.6.2.0","id":"CVE-2018-7790","kev_date_added":null,"published":"2018-08-29"},{"cvss_score":9.8,"headline":"Auth bypass in Modicon M221, all references, all versions prior to firmware V1.6.2.0","id":"CVE-2018-7791","kev_date_added":null,"published":"2018-08-29"},{"cvss_score":7.5,"headline":"Denial of service in SoMachine Basic and Modicon M221, SoMachine Basic, all versions Modicon M221, all references, all versions prior to firmware V1.10.0.0","id":"CVE-2018-7821","kev_date_added":null,"published":"2019-05-22"},{"cvss_score":7.5,"headline":"Weak cryptography in Modicon M221, all references, all versions prior to firmware V1.6.2.0","id":"CVE-2018-7792","kev_date_added":null,"published":"2018-08-29"},{"cvss_score":7.1,"headline":"Weak cryptography in Modicon M221, all references, all versions","id":"CVE-2020-7565","kev_date_added":null,"published":"2020-11-19"},{"cvss_score":7.1,"headline":"Weak cryptography in Modicon M221, all references, all versions","id":"CVE-2020-7566","kev_date_added":null,"published":"2020-11-19"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-29","vendors":["n/a"]},"summary":"Attackers can capture network traffic to disclose non-sensitive information from Modicon M221 controllers communicating with EcoStruxure Machine - Basic software.","url":"https://insights.sbomify.com/CVE-2020-7568/"}
