An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2018-7823 and fix it if it is affected.\n\nWhat it is: CVE-2018-7823 is a medium-severity vulnerability in SoMachine Basic and Modicon M221, SoMachine Basic, all versions Modicon M221, all references, all versions prior to firmware V1.10.0.0, published on 22 May 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-2018-7823 in the wild and no public exploit code.\n\nAffected product: SoMachine Basic and Modicon M221, SoMachine Basic, all versions Modicon M221, all references, all versions prior to firmware V1.10.0.0. 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-2018-7823/ (Markdown: https://insights.sbomify.com/CVE-2018-7823/index.md)","id":"CVE-2018-7823","markdown":"https://insights.sbomify.com/CVE-2018-7823/index.md","name":"CVE-2018-7823","record":{"aliases":["GHSA-7424-xwr7-g6pc"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"PLC and engineering software","requires_auth":"none","summary":"Remote attackers can trigger the launch of SoMachine Basic via crafted Ethernet messages, potentially leading to unauthorized execution in Schneider Electric industrial control systems.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"schneider","cpe":[{"product":"modicon_m221_firmware","vendor":"schneider-electric"},{"product":"somachine_basic","vendor":"schneider-electric"}],"cvss":{"score":5.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[],"description":"A Environment (CWE-2) vulnerability exists in SoMachine Basic, all versions, and Modicon M221(all references, all versions prior to firmware V1.10.0.0) which could cause remote launch of SoMachine Basic when sending crafted ethernet message.","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":"Other 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-2018-7823","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2018"},"n_packages":0,"n_references":1,"next":{"headline":"Path traversal in Schneider Electric Modbus Serial Driver (For 64-bit Windows OS:V3.17 IE 37 and prior , For 32-bit Windows OS:V2.17 IE 27 and prior, and as part of the Driver Suite version:V14.12 and prior)","id":"CVE-2018-7824"},"packages":[],"prev":{"headline":"Misconfiguration 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-2018-7822"},"products":["SoMachine Basic and Modicon M221, SoMachine Basic, all versions Modicon M221, all references, all versions prior to firmware V1.10.0.0"],"published":"2019-05-22","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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"Remote attackers can trigger the launch of SoMachine Basic via crafted Ethernet messages, potentially leading to unauthorized execution in Schneider Electric industrial control systems.","url":"https://insights.sbomify.com/CVE-2018-7823/"}
