An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2023-31409 and fix it if it is affected.\n\nWhat it is: CVE-2023-31409 is a medium-severity denial of service vulnerability in SICK FTMG-ESD15AXX AIR FLOW SENSOR, published on 15 May 2023. 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-2023-31409 in the wild and no public exploit code.\n\nAffected product: SICK FTMG-ESD15AXX AIR FLOW SENSOR. 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-2023-31409/ (Markdown: https://insights.sbomify.com/CVE-2023-31409/index.md)","id":"CVE-2023-31409","markdown":"https://insights.sbomify.com/CVE-2023-31409/index.md","name":"CVE-2023-31409","record":{"aliases":["GHSA-7c4w-rgx7-j66j"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"SICK air flow sensor","requires_auth":"none","summary":"Remote attackers can cause denial of service on SICK air flow sensors via Slowloris-style HTTP attacks, affecting industrial availability.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"SICK AG","cpe":[{"product":"ftmg-esd15axx_firmware","vendor":"sick"},{"product":"ftmg-esd20axx_firmware","vendor":"sick"},{"product":"ftmg-esd25axx_firmware","vendor":"sick"},{"product":"ftmg-esn40sxx_firmware","vendor":"sick"},{"product":"ftmg-esn50sxx_firmware","vendor":"sick"},{"product":"ftmg-esr40sxx_firmware","vendor":"sick"},{"product":"ftmg-esr50sxx_firmware","vendor":"sick"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"Uncontrolled Resource Consumption in SICK FTMg AIR FLOW SENSOR with Partnumbers 1100214, 1100215, 1100216, 1120114, 1120116, 1122524, 1122526 allows an remote attacker to influence the availability of the webserver by invocing a Slowloris style attack via HTTP requests.","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 SICK FTMG-ESD15AXX AIR FLOW SENSOR","id":"CVE-2023-31409","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":"Information disclosure in EventCam App","id":"CVE-2023-31410"},"packages":[],"prev":{"headline":"Cross-site scripting in SICK FTMG-ESD15AXX AIR FLOW SENSOR","id":"CVE-2023-31408"},"products":["SICK FTMG-ESD15AXX AIR FLOW SENSOR","SICK FTMG-ESD20AXX AIR FLOW SENSOR","SICK FTMG-ESD25AXX AIR FLOW SENSOR","SICK FTMG-ESN40SXX AIR FLOW SENSOR","SICK FTMG-ESN50SXX AIR FLOW SENSOR","SICK FTMG-ESR40SXX AIR FLOW SENSOR","SICK FTMG-ESR50SXX AIR FLOW SENSOR"],"published":"2023-05-15","related":[{"cvss_score":7.5,"headline":"Missing authorization in SICK FTMG-ESD15AXX AIR FLOW SENSOR","id":"CVE-2023-23445","kev_date_added":null,"published":"2023-05-15"},{"cvss_score":7.5,"headline":"Missing authorization in SICK FTMG-ESD15AXX AIR FLOW SENSOR","id":"CVE-2023-23446","kev_date_added":null,"published":"2023-05-15"},{"cvss_score":7.5,"headline":"Denial of service in SICK FTMG-ESD15AXX AIR FLOW SENSOR","id":"CVE-2023-23447","kev_date_added":null,"published":"2023-05-15"},{"cvss_score":6.2,"headline":"Auth bypass in SICK FTMG-ESD15AXX AIR FLOW SENSOR","id":"CVE-2023-23450","kev_date_added":null,"published":"2023-05-15"},{"cvss_score":5.3,"headline":"Information disclosure in SICK FTMG-ESD15AXX AIR FLOW SENSOR","id":"CVE-2023-23448","kev_date_added":null,"published":"2023-05-15"},{"cvss_score":5.3,"headline":"Information disclosure in SICK FTMG-ESD15AXX AIR FLOW SENSOR","id":"CVE-2023-23449","kev_date_added":null,"published":"2023-05-15"},{"cvss_score":5.3,"headline":"Cross-site scripting in SICK FTMG-ESD15AXX AIR FLOW SENSOR","id":"CVE-2023-31408","kev_date_added":null,"published":"2023-05-15"}],"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 cause denial of service on SICK air flow sensors via Slowloris-style HTTP attacks, affecting industrial availability.","url":"https://insights.sbomify.com/CVE-2023-31409/"}
