An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2019-10977 and fix it if it is affected.\n\nWhat it is: CVE-2019-10977 is a high-severity denial of service vulnerability in Mitsubishi Electric MELSEC-Q series Ethernet module, published on 23 May 2019. 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-2019-10977 in the wild and no public exploit code.\n\nAffected product: Mitsubishi Electric MELSEC-Q series Ethernet module. 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-2019-10977/ (Markdown: https://insights.sbomify.com/CVE-2019-10977/index.md)","id":"CVE-2019-10977","markdown":"https://insights.sbomify.com/CVE-2019-10977/index.md","name":"CVE-2019-10977","record":{"aliases":["GHSA-3fgw-638m-mm8f"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Mitsubishi Ethernet module","requires_auth":"none","summary":"An attacker can cause a denial-of-service condition on Mitsubishi MELSEC-Q Ethernet modules by sending crafted TCP packets to the FTP service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"qj71e71-100_firmware","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-755","name":"Improper Handling of Exceptional Conditions"},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"In Mitsubishi Electric MELSEC-Q series Ethernet module QJ71E71-100 serial number 20121 and prior, an attacker could send crafted TCP packets against the FTP service, forcing the target devices to enter an error mode and cause a denial-of-service condition.","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":"Denial of service in MELSEC-Q series Ethernet module","id":"CVE-2019-10977","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2019"},"n_packages":0,"n_references":2,"next":{"headline":"Memory corruption in Red Lion Controls Crimson (Windows configuration software)","id":"CVE-2019-10978"},"packages":[],"prev":{"headline":"XML external entity in Mitsubishi Electric FR Configurator2","id":"CVE-2019-10976"},"products":["MELSEC-Q series Ethernet module"],"published":"2019-05-23","related":[{"cvss_score":8.6,"headline":"Denial of service in Mitsubishi Electric MELSEC-Q Series Ethernet Interface Module","id":"CVE-2016-8368","kev_date_added":null,"published":"2017-02-13"},{"cvss_score":7.5,"headline":"Weak cryptography in Mitsubishi Electric MELSEC-Q Series Ethernet Interface Module","id":"CVE-2016-8370","kev_date_added":null,"published":"2017-02-13"}],"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"]},"summary":"An attacker can cause a denial-of-service condition on Mitsubishi MELSEC-Q Ethernet modules by sending crafted TCP packets to the FTP service.","url":"https://insights.sbomify.com/CVE-2019-10977/"}
