An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2018-19016 and fix it if it is affected.\n\nWhat it is: CVE-2018-19016 is a high-severity denial of service vulnerability in Rockwell Automation EtherNet/IP Web Server Modules 1756-EWEB (includes 1756-EWEBK) Version 5.001 and earlier, and CompactLogix 1768-EWEB Version 2.005 and earlier., published on 27 Mar 2019. 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-2018-19016 in the wild and no public exploit code.\n\nAffected product: Rockwell Automation EtherNet/IP Web Server Modules 1756-EWEB (includes 1756-EWEBK) Version 5.001 and earlier, and CompactLogix 1768-EWEB Version 2.005 and earlier.. 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-2018-19016/ (Markdown: https://insights.sbomify.com/CVE-2018-19016/index.md)","id":"CVE-2018-19016","markdown":"https://insights.sbomify.com/CVE-2018-19016/index.md","name":"CVE-2018-19016","record":{"aliases":["GHSA-c7x4-832f-v26q"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial network module","requires_auth":"none","summary":"A remote attacker can cause a denial-of-service condition in Rockwell Automation EtherNet/IP Web Server Modules by sending a crafted UDP packet to the SNMP service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"ethernet\\/ip_web_server_module_1756-eweb","vendor":"rockwellautomation"},{"product":"ethernet\\/ip_web_server_module_1768-eweb","vendor":"rockwellautomation"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Rockwell Automation EtherNet/IP Web Server Modules 1756-EWEB (includes 1756-EWEBK) Version 5.001 and earlier, and CompactLogix 1768-EWEB Version 2.005 and earlier.
