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-2023-6943 in the wild and no public exploit code.\n\nAffected product: Mitsubishi Electric Corporation EZSocket. 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-2023-6943/ (Markdown: https://insights.sbomify.com/CVE-2023-6943/index.md)","id":"CVE-2023-6943","markdown":"https://insights.sbomify.com/CVE-2023-6943/index.md","name":"CVE-2023-6943","record":{"aliases":["GHSA-8g5q-mp2w-j766"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Mitsubishi PLC software","requires_auth":"none","summary":"Remote attackers can execute malicious code via unsafe reflection in Mitsubishi Electric industrial automation software.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mitsubishi","cpe":[{"product":"ezsocket","vendor":"mitsubishielectric"},{"product":"fr_configurator2","vendor":"mitsubishielectric"},{"product":"got1000","vendor":"mitsubishielectric"},{"product":"got2000","vendor":"mitsubishielectric"},{"product":"gx_works2","vendor":"mitsubishielectric"},{"product":"gx_works3","vendor":"mitsubishielectric"},{"product":"mc_works64","vendor":"mitsubishielectric"},{"product":"melsoft_navigator","vendor":"mitsubishielectric"},{"product":"mt_works2","vendor":"mitsubishielectric"},{"product":"mx_component","vendor":"mitsubishielectric"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-470","name":"Use of Externally-Controlled Input to Select Classes or Code"}],"description":"Use of Externally-Controlled Input to Select Classes or Code ('Unsafe Reflection') vulnerability in Mitsubishi Electric Corporation EZSocket versions 3.0 to 5.92, GT Designer3 Version1(GOT1000) versions 1.325P and prior, GT Designer3 Version1(GOT2000) versions 1.320J and prior, GX Works2 versions 1.11M to 1.626C, GX Works3 versions 1.106L and prior, MELSOFT Navigator versions 1.04E to 2.102G, MT Works2 versions 1.190Y and prior, MX Component versions 4.00A to 5.007H and MX OPC Server DA/UA all versions allows a remote unauthenticated attacker to execute a malicious code by RPC with a path to a malicious library while connected to the products.","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":"Code injection in EZSocket","id":"CVE-2023-6943","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2023"},"n_packages":0,"n_references":3,"next":{"headline":"Rhdh: catalog-import function leaks credentials to frontend","id":"CVE-2023-6944"},"packages":[],"prev":{"headline":"Auth bypass in EZSocket","id":"CVE-2023-6942"},"products":["EZSocket","GT Designer3 Version1(GOT1000)","GT Designer3 Version1(GOT2000)","GX Works2","GX Works3","MELSOFT Navigator","MT Works2","MX Component","MX OPC Server DA/UA"],"published":"2024-01-30","related":[{"cvss_score":7.5,"headline":"Auth bypass in EZSocket","id":"CVE-2023-6942","kev_date_added":null,"published":"2024-01-30"},{"cvss_score":5.5,"headline":"Denial of service in Mitsubishi Electric GX Works2; Mitsubishi Electric MELSOFT Navigator; Mitsubishi Electric EZSocket","id":"CVE-2021-20606","kev_date_added":null,"published":"2021-12-17"},{"cvss_score":5.5,"headline":"Integer overflow in Mitsubishi Electric GX Works2; Mitsubishi Electric MELSOFT Navigator; Mitsubishi Electric EZSocket","id":"CVE-2021-20607","kev_date_added":null,"published":"2021-12-17"}],"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":"total"},"state":"PUBLISHED","updated":"2025-09-19","vendors":["Mitsubishi Electric Corporation"]},"summary":"Remote attackers can execute malicious code via unsafe reflection in Mitsubishi Electric industrial automation software.","url":"https://insights.sbomify.com/CVE-2023-6943/"}
