An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-5531 and fix it if it is affected.\n\nWhat it is: CVE-2020-5531 is a critical vulnerability in Mitsubishi Electric MELSEC C Controller Module and MELIPC Series MI5000, published on 17 Feb 2020. 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-2020-5531 in the wild and no public exploit code.\n\nAffected product: Mitsubishi Electric MELSEC C Controller Module and MELIPC Series MI5000. 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-2020-5531/ (Markdown: https://insights.sbomify.com/CVE-2020-5531/index.md)","id":"CVE-2020-5531","markdown":"https://insights.sbomify.com/CVE-2020-5531/index.md","name":"CVE-2020-5531","record":{"aliases":["GHSA-ffqg-m22j-5p83"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Mitsubishi PLC controller","requires_auth":"none","summary":"Remote attackers can cause denial of service or execute malware on Mitsubishi Electric MELSEC controllers via unspecified vectors.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"mi5122-vw_firmware","vendor":"mitsubishielectric"},{"product":"q24dhccpu-v_firmware","vendor":"mitsubishielectric"},{"product":"q24dhccpu-vg_firmware","vendor":"mitsubishielectric"},{"product":"r12ccpu-v_firmware","vendor":"mitsubishielectric"},{"product":"rd55up06-v_firmware","vendor":"mitsubishielectric"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"Mitsubishi Electric MELSEC C Controller Module and MELIPC Series MI5000 MELSEC-Q Series C Controller Module(Q24DHCCPU-V, Q24DHCCPU-VG User Ethernet port (CH1, CH2): First 5 digits of serial number 21121 or before), MELSEC iQ-R Series C Controller Module / C Intelligent Function Module(R12CCPU-V Ethernet port (CH1, CH2): First 2 digits of serial number 11 or before, and RD55UP06-V Ethernet port: First 2 digits of serial number 08 or before), and MELIPC Series MI5000(MI5122-VW Ethernet port (CH1): First 2 digits of serial number 03 or before, or the firmware version 03 or before) allow remote attackers to cause a denial of service and/or malware being executed via unspecified vectors.","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 Mitsubishi Electric MELSEC C Controller Module and MELIPC Series MI5000","id":"CVE-2020-5531","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Auth bypass in ilbo App","id":"CVE-2020-5532"},"packages":[],"prev":{"headline":"Cross-site request forgery in Easy Property Listings","id":"CVE-2020-5530"},"products":["Mitsubishi Electric MELSEC C Controller Module and MELIPC Series MI5000"],"published":"2020-02-17","related":[],"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":"2024-08-04","vendors":["Mitsubishi Electric Corporation"]},"summary":"Remote attackers can cause denial of service or execute malware on Mitsubishi Electric MELSEC controllers via unspecified vectors.","url":"https://insights.sbomify.com/CVE-2020-5531/"}
