An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-5597 and fix it if it is affected.\n\nWhat it is: CVE-2020-5597 is a high-severity vulnerability in Mitsubishi Electric Corporation GOT2000 series GT27, GT25, and GT23, published on 7 Jul 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-2020-5597 in the wild and no public exploit code.\n\nAffected product: Mitsubishi Electric Corporation GOT2000 series GT27, GT25, and GT23. 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-2020-5597/ (Markdown: https://insights.sbomify.com/CVE-2020-5597/index.md)","id":"CVE-2020-5597","markdown":"https://insights.sbomify.com/CVE-2020-5597/index.md","name":"CVE-2020-5597","record":{"aliases":["GHSA-xvm6-4q8f-x3f5"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial HMI firmware","requires_auth":"none","summary":"Remote attackers can cause denial of service or execute arbitrary code on Mitsubishi Electric GOT2000 HMIs via crafted packets.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"coreos","vendor":"mitsubishielectric"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"TCP/IP function included in the firmware of Mitsubishi Electric GOT2000 series (CoreOS with version -Y and earlier installed in GT27 Model, GT25 Model, and GT23 Model) contains a null pointer dereference vulnerability, which may allow a remote attacker to stop the network functions of the products or execute a malicious program via a specially crafted packet.","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":"Null dereference in GOT2000 series GT27, GT25, and GT23","id":"CVE-2020-5597","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Auth bypass in GOT2000 series GT27, GT25, and GT23","id":"CVE-2020-5598"},"packages":[],"prev":{"headline":"Other in GOT2000 series GT27, GT25, and GT23","id":"CVE-2020-5596"},"products":["GOT2000 series GT27, GT25, and GT23"],"published":"2020-07-07","related":[{"cvss_score":9.8,"headline":"Memory corruption in GT14 Model of GOT 1000 series","id":"CVE-2020-5644","kev_date_added":null,"published":"2020-11-06"},{"cvss_score":9.8,"headline":"Missing authorization in GT14 Model of GOT 1000 series","id":"CVE-2020-5647","kev_date_added":null,"published":"2020-11-06"},{"cvss_score":9.8,"headline":"Command injection in GT14 Model of GOT 1000 series","id":"CVE-2020-5648","kev_date_added":null,"published":"2020-11-06"},{"cvss_score":9.8,"headline":"Memory corruption in GOT2000 series GT27, GT25, and GT23","id":"CVE-2020-5595","kev_date_added":null,"published":"2020-07-07"},{"cvss_score":9.8,"headline":"Command injection in GOT2000 series GT27, GT25, and GT23","id":"CVE-2020-5599","kev_date_added":null,"published":"2020-07-07"},{"cvss_score":7.5,"headline":"Auth bypass in GT14 Model of GOT 1000 series","id":"CVE-2020-5645","kev_date_added":null,"published":"2020-11-06"},{"cvss_score":7.5,"headline":"Null dereference in GT14 Model of GOT 1000 series","id":"CVE-2020-5646","kev_date_added":null,"published":"2020-11-06"}],"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":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 arbitrary code on Mitsubishi Electric GOT2000 HMIs via crafted packets.","url":"https://insights.sbomify.com/CVE-2020-5597/"}
