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-2019-13555/ (Markdown: https://insights.sbomify.com/CVE-2019-13555/index.md)","id":"CVE-2019-13555","markdown":"https://insights.sbomify.com/CVE-2019-13555/index.md","name":"CVE-2019-13555","record":{"aliases":["GHSA-r5rh-4cpr-qxhj"],"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":"A remote attacker can cause a denial-of-service condition in Mitsubishi Electric MELSEC PLCs by exploiting a timing-dependent flaw in the FTP service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"l02\\/06\\/26cpu-cm_firmware","vendor":"mitsubishielectric"},{"product":"l02\\/06\\/26cpu-p_firmware","vendor":"mitsubishielectric"},{"product":"l02\\/06\\/26cpu_firmware","vendor":"mitsubishielectric"},{"product":"l26cpu-bt-cm_firmware","vendor":"mitsubishielectric"},{"product":"l26cpu-bt_firmware","vendor":"mitsubishielectric"},{"product":"l26cpu-pbt_firmware","vendor":"mitsubishielectric"},{"product":"q03\\/04\\/06\\/13\\/26udvcpu_firmware","vendor":"mitsubishielectric"},{"product":"q03udecpu_firmware","vendor":"mitsubishielectric"},{"product":"q04\\/06\\/10\\/13\\/20\\/26\\/50\\/100udehcpu_firmware","vendor":"mitsubishielectric"},{"product":"q04\\/06\\/13\\/26udpvcpu_firmware","vendor":"mitsubishielectric"}],"cvss":{"score":5.9,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"In Mitsubishi Electric MELSEC-Q Series Q03/04/06/13/26UDVCPU: serial number 21081 and prior, Q04/06/13/26UDPVCPU: serial number 21081 and prior, and Q03UDECPU, Q04/06/10/13/20/26/50/100UDEHCPU: serial number 21081 and prior, MELSEC-L Series L02/06/26CPU, L26CPU-BT: serial number 21101 and prior, L02/06/26CPU-P, L26CPU-PBT: serial number 21101 and prior, and L02/06/26CPU-CM, L26CPU-BT-CM: serial number 21101 and prior, a remote attacker can cause the FTP service to enter a denial-of-service condition dependent on the timing at which a remote attacker connects to the FTP server on the above CPU modules.","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 Mitsubishi Electric MELSEC-Q Series Q03/04/06/13/26UDVCPU: serial number 21081 and prior, Q04/06/13/26UDPVCPU: serial number 21081 and prior, and Q03UDECPU, Q04/06/10/13/20/26/50/100UDEHCPU: serial number 21081 and prior.
