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-2023-4418 in the wild and no public exploit code.\n\nAffected product: SICK AG LMS5xx. 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-2023-4418/ (Markdown: https://insights.sbomify.com/CVE-2023-4418/index.md)","id":"CVE-2023-4418","markdown":"https://insights.sbomify.com/CVE-2023-4418/index.md","name":"CVE-2023-4418","record":{"aliases":["GHSA-xqcv-p45j-c72q"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"LMS5xx laser scanner","requires_auth":"none","summary":"Remote attackers can disrupt availability of SICK LMS5xx laser scanners via TCP SYN flood, impacting industrial operations.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"SICK AG","cpe":[{"product":"lms500_firmware","vendor":"sick"},{"product":"lms511_firmware","vendor":"sick"},{"product":"lms531_firmware","vendor":"sick"}],"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":"A remote unprivileged attacker can sent multiple packages to the LMS5xx to disrupt its availability through a TCP SYN-based denial-of-service (DDoS) attack. \nBy exploiting this vulnerability, an attacker can flood the targeted LMS5xx with a high volume of TCP SYN requests, overwhelming its resources and causing it to become unresponsive or unavailable for legitimate users.","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 LMS5xx","id":"CVE-2023-4418","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2023"},"n_packages":0,"n_references":3,"next":{"headline":"Hardcoded credentials in LMS5xx","id":"CVE-2023-4419"},"packages":[],"prev":{"headline":"Missing authorization in Remote Desktop Manager","id":"CVE-2023-4417"},"products":["LMS5xx"],"published":"2023-08-24","related":[{"cvss_score":9.8,"headline":"Hardcoded credentials in LMS5xx","id":"CVE-2023-4419","kev_date_added":null,"published":"2023-08-24"},{"cvss_score":9.8,"headline":"Information disclosure in LMS5xx","id":"CVE-2023-4420","kev_date_added":null,"published":"2023-08-24"},{"cvss_score":7.5,"headline":"Weak cryptography in LMS5xx","id":"CVE-2023-31412","kev_date_added":null,"published":"2023-08-24"}],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-06-01","vendors":["SICK AG"]},"summary":"Remote attackers can disrupt availability of SICK LMS5xx laser scanners via TCP SYN flood, impacting industrial operations.","url":"https://insights.sbomify.com/CVE-2023-4418/"}
