An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2024-8936 and fix it if it is affected.\n\nWhat it is: CVE-2024-8936 is a high-severity vulnerability in Schneider Electric Modicon M340 CPU (part numbers BMXP34*), published on 13 Nov 2024. 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-2024-8936 in the wild and no public exploit code.\n\nAffected product: Schneider Electric Modicon M340 CPU (part numbers BMXP34*). 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-2024-8936/ (Markdown: https://insights.sbomify.com/CVE-2024-8936/index.md)","id":"CVE-2024-8936","markdown":"https://insights.sbomify.com/CVE-2024-8936/index.md","name":"CVE-2024-8936","record":{"aliases":["GHSA-rrmf-46w6-f74r"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Modicon PLC","requires_auth":"none","summary":"An attacker can read controller memory via a crafted Modbus request after a Man-In-The-Middle attack on Schneider Electric Modicon M340 CPUs.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"schneider","cpe":[],"cvss":{"score":8.3,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"CWE-20: Improper Input Validation vulnerability exists that could lead to loss of confidentiality of controller memory\nafter a successful Man-In-The-Middle attack followed by sending a crafted Modbus function call used to tamper\nwith memory.","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 M340 CPU (part numbers BMXP34*)","id":"CVE-2024-8936","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2024"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in Modicon M340 CPU (part numbers BMXP34*)","id":"CVE-2024-8937"},"packages":[],"prev":{"headline":"Auth bypass in Modicon M340 CPU (part numbers BMXP34*)","id":"CVE-2024-8935"},"products":["Modicon M340 CPU (part numbers BMXP34*)"],"published":"2024-11-13","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2024-11-13","vendors":["Schneider Electric"]},"summary":"An attacker can read controller memory via a crafted Modbus request after a Man-In-The-Middle attack on Schneider Electric Modicon M340 CPUs.","url":"https://insights.sbomify.com/CVE-2024-8936/"}
