An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2018-7798 and fix it if it is affected.\n\nWhat it is: CVE-2018-7798 is a high-severity missing authorization vulnerability in Schneider Electric SE Modicon M221, All Versions, published on 2 Nov 2018. 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-2018-7798 in the wild and no public exploit code.\n\nAffected product: Schneider Electric SE Modicon M221, 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-2018-7798/ (Markdown: https://insights.sbomify.com/CVE-2018-7798/index.md)","id":"CVE-2018-7798","markdown":"https://insights.sbomify.com/CVE-2018-7798/index.md","name":"CVE-2018-7798","record":{"aliases":["GHSA-wcc5-wx82-x4gx"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Modicon PLC","requires_auth":"none","summary":"An attacker can remotely modify IPv4 network settings on Schneider Modicon M221 devices due to insufficient data authenticity verification.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"schneider","cpe":[{"product":"somachine_basic","vendor":"schneider-electric"}],"cvss":{"score":8.2,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:L","version":"3.1"},"cwes":[{"id":"CWE-345","name":"Insufficient Verification of Data Authenticity"}],"description":"A Insufficient Verification of Data Authenticity (CWE-345) vulnerability exists in the Modicon M221, all versions, which could cause a change of IPv4 configuration (IP address, mask and gateway) when remotely connected to the device.","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":"Missing authorization in Modicon M221, All Versions","id":"CVE-2018-7798","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2018"},"n_packages":0,"n_references":2,"next":{"headline":"Code injection in Schneider Electric Software Update (SESU), all versions prior to V2.2.0","id":"CVE-2018-7799"},"packages":[],"prev":{"headline":"Open redirect in Power Monitoring Expert, Energy Expert (formerly Power Manager) - EcoStruxure\u0026#xaa; Power Monitoring Expert (PME) v8.2 (all editions), EcoStruxure\u0026#xaa; Energy Expert 1.3 (formerly Power Manager), EcoStruxure\u0026#xaa; Power SCADA Operation (PSO) 8.2 Advanced Reports and Dashboards Module, EcoStruxure\u0026#xaa; Power Monitoring Expert (PME) v9.0, EcoStruxure\u0026#xaa; Energy Expert v2.0, and EcoStruxure\u0026#xaa;Power SCADA Operation (PSO) 9.0 Advanced Reports and Dashboards Module","id":"CVE-2018-7797"},"products":["Modicon M221, All Versions"],"published":"2018-11-02","related":[{"cvss_score":7.5,"headline":"XML external entity in SoMachine Basic","id":"CVE-2018-7783","kev_date_added":null,"published":"2018-07-03"}],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-29","vendors":["Schneider Electric SE"]},"summary":"An attacker can remotely modify IPv4 network settings on Schneider Modicon M221 devices due to insufficient data authenticity verification.","url":"https://insights.sbomify.com/CVE-2018-7798/"}
