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-2019-6535 in the wild and no public exploit code.\n\nAffected product: Mitsubishi Electric Q03/04/06/13/26UDVCPU. 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-2019-6535/ (Markdown: https://insights.sbomify.com/CVE-2019-6535/index.md)","id":"CVE-2019-6535","markdown":"https://insights.sbomify.com/CVE-2019-6535/index.md","name":"CVE-2019-6535","record":{"aliases":["GHSA-6j5w-96r9-mm4v"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Mitsubishi PLC","requires_auth":"none","summary":"Remote attackers can crash the Ethernet stack and disrupt USB communication on Mitsubishi MELSEC-Q PLCs by sending specific bytes to Port 5007.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"q03udecpu_firmware","vendor":"mitsubishielectric"},{"product":"q03udvcpu_firmware","vendor":"mitsubishielectric"},{"product":"q04udehcpu_firmware","vendor":"mitsubishielectric"},{"product":"q04udpvcpu_firmware","vendor":"mitsubishielectric"},{"product":"q04udvcpu_firmware","vendor":"mitsubishielectric"},{"product":"q06udehcpu_firmware","vendor":"mitsubishielectric"},{"product":"q06udpvcpu_firmware","vendor":"mitsubishielectric"},{"product":"q06udvcpu_firmware","vendor":"mitsubishielectric"},{"product":"q100udehcpu_firmware","vendor":"mitsubishielectric"},{"product":"q10udehcpu_firmware","vendor":"mitsubishielectric"},{"product":"q13udehcpu_firmware","vendor":"mitsubishielectric"},{"product":"q13udpvcpu_firmware","vendor":"mitsubishielectric"},{"product":"q13udvcpu_firmware","vendor":"mitsubishielectric"},{"product":"q20udehcpu_firmware","vendor":"mitsubishielectric"},{"product":"q26udehcpu_firmware","vendor":"mitsubishielectric"},{"product":"q26udpvcpu_firmware","vendor":"mitsubishielectric"},{"product":"q26udvcpu_firmware","vendor":"mitsubishielectric"},{"product":"q50udehcpu_firmware","vendor":"mitsubishielectric"}],"cvss":{"score":7.5,"severity":"high","source":"cna","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-400","name":"Uncontrolled Resource Consumption"}],"description":"Mitsubishi Electric Q03/04/06/13/26UDVCPU: serial number 20081 and prior, Q04/06/13/26UDPVCPU: serial number 20081 and prior, and Q03UDECPU, Q04/06/10/13/20/26/50/100UDEHCPU: serial number 20101 and prior.
