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-2018-17924 in the wild and no public exploit code.\n\nAffected product: Rockwell Automation. 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-2018-17924/ (Markdown: https://insights.sbomify.com/CVE-2018-17924/index.md)","id":"CVE-2018-17924","markdown":"https://insights.sbomify.com/CVE-2018-17924/index.md","name":"CVE-2018-17924","record":{"aliases":["GHSA-w6vr-5wrp-c9p7"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["denial_of_service","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial PLC","requires_auth":"none","summary":"Unauthenticated attackers can modify IP configurations on Rockwell controllers, causing communication loss and denial of service.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"1756-en2f_series_a_firmware","vendor":"rockwellautomation"},{"product":"1756-en2f_series_b_firmware","vendor":"rockwellautomation"},{"product":"1756-en2f_series_c_firmware","vendor":"rockwellautomation"},{"product":"1756-en2t_series_a_firmware","vendor":"rockwellautomation"},{"product":"1756-en2t_series_b_firmware","vendor":"rockwellautomation"},{"product":"1756-en2t_series_c_firmware","vendor":"rockwellautomation"},{"product":"1756-en2t_series_d_firmware","vendor":"rockwellautomation"},{"product":"1756-en2tr_series_a_firmware","vendor":"rockwellautomation"},{"product":"1756-en2tr_series_b_firmware","vendor":"rockwellautomation"},{"product":"1756-en2tr_series_c_firmware","vendor":"rockwellautomation"},{"product":"1756-en3tr_series_a_firmware","vendor":"rockwellautomation"},{"product":"1756-en3tr_series_b_firmware","vendor":"rockwellautomation"},{"product":"1756-enbt_firmware","vendor":"rockwellautomation"},{"product":"1756-eweb_series_a_firmware","vendor":"rockwellautomation"},{"product":"1756-eweb_series_b_firmware","vendor":"rockwellautomation"},{"product":"micrologix_1400_firmware","vendor":"rockwellautomation"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","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-306","name":"Missing Authentication for Critical Functionality"}],"description":"Rockwell Automation MicroLogix 1400 Controllers and 1756 ControlLogix Communications Modules An unauthenticated, remote threat actor could send a CIP connection request to an affected device, and upon successful connection, send a new IP configuration to the affected device even if the controller in the system is set to Hard RUN mode.
