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-2025-14027 in the wild and no public exploit code.\n\nAffected product: Rockwell Automation ControlLogix® Redundancy Enhanced Module. 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-2025-14027/ (Markdown: https://insights.sbomify.com/CVE-2025-14027/index.md)","id":"CVE-2025-14027","markdown":"https://insights.sbomify.com/CVE-2025-14027/index.md","name":"CVE-2025-14027","record":{"aliases":["GHSA-xwj8-ppx9-j533"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"ControlLogix Redundancy Module","requires_auth":"none","summary":"Attackers can cause denial of service on Rockwell ControlLogix Redundancy Modules via crafted inputs, requiring an upgrade to the newer module version.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Rockwell","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-401","name":"Missing Release of Memory after Effective Lifetime"}],"description":"Multiple denial-of-service vulnerabilities exist in the affected product.
