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-2024-8937 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-2024-8937/ (Markdown: https://insights.sbomify.com/CVE-2024-8937/index.md)","id":"CVE-2024-8937","markdown":"https://insights.sbomify.com/CVE-2024-8937/index.md","name":"CVE-2024-8937","record":{"aliases":["GHSA-9pjf-rrr2-qjqf"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"PLC CPU","requires_auth":"none","summary":"A memory corruption vulnerability in Schneider Electric PLCs allows arbitrary code execution via crafted Modbus packets after a Man-in-the-Middle attack.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability exists that could\ncause a potential arbitrary code execution after a successful Man-In-The Middle attack followed by sending a\ncrafted Modbus function call to tamper with memory area involved in the authentication process.","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 M340 CPU (part numbers BMXP34*)","id":"CVE-2024-8937","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2024"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in Modicon M340 CPU (part numbers BMXP34*)","id":"CVE-2024-8938"},"packages":[],"prev":{"headline":"Information disclosure in Modicon M340 CPU (part numbers BMXP34*)","id":"CVE-2024-8936"},"products":["Modicon M340 CPU (part numbers BMXP34*)","Modicon MC80 (part numbers BMKC80)","Modicon Momentum Unity M1E Processor (171CBU*)"],"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":"A memory corruption vulnerability in Schneider Electric PLCs allows arbitrary code execution via crafted Modbus packets after a Man-in-the-Middle attack.","url":"https://insights.sbomify.com/CVE-2024-8937/"}
