An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2026-8805 and fix it if it is affected.\n\nWhat it is: CVE-2026-8805 is a high-severity vulnerability in Mitsubishi Electric MELSEC iQ-F Series FX5-EIP EtherNet/IP Module FX5-EIP, published on 19 Jun 2026. 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-2026-8805 in the wild and no public exploit code.\n\nAffected product: Mitsubishi Electric MELSEC iQ-F Series FX5-EIP EtherNet/IP Module FX5-EIP. 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-2026-8805/ (Markdown: https://insights.sbomify.com/CVE-2026-8805/index.md)","id":"CVE-2026-8805","markdown":"https://insights.sbomify.com/CVE-2026-8805/index.md","name":"CVE-2026-8805","record":{"aliases":["GHSA-hc5r-cmjq-47w9"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"PLC EtherNet/IP module","requires_auth":"none","summary":"Remote attackers can cause denial of service in Mitsubishi MELSEC iQ-F EtherNet/IP modules by rapidly establishing numerous TCP connections, triggering an integer overflow.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mitsubishi","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"Integer Overflow or Wraparound vulnerability in the EtherNet/IP function of Mitsubishi Electric MELSEC iQ-F Series FX5-EIP EtherNet/IP module FX5-EIP versions 1.000 and prior allows a remote attacker to cause a denial-of-service (DoS) condition in the affected product by rapidly establishing a large number of TCP connections to it, resulting in an inconsistency in the product's internal connection management process and triggering improper memory access.","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 (DoS) vulnerability in MELSEC iQ-F Series EtherNet/IP module","id":"CVE-2026-8805","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Denial-of-service (DoS) vulnerability in MELSEC iQ-F Series FX5-ENET/IP Ethernet module","id":"CVE-2026-8806"},"packages":[],"prev":{"headline":"Cleartext Storage of Sensitive Information for Puppet Resource API","id":"CVE-2026-8804"},"products":["Mitsubishi Electric MELSEC iQ-F Series FX5-EIP EtherNet/IP Module FX5-EIP"],"published":"2026-06-19","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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-06-22","vendors":["Mitsubishi Electric Corporation"]},"summary":"Remote attackers can cause denial of service in Mitsubishi MELSEC iQ-F EtherNet/IP modules by rapidly establishing numerous TCP connections, triggering an integer overflow.","url":"https://insights.sbomify.com/CVE-2026-8805/"}
