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-2012-6442 in the wild and no public exploit code.\n\nAffected product: Rockwell Automation 1756-ENBT, 1756-EWEB, 1768-ENBT, 1768-EWEB communication modules. 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-2012-6442/ (Markdown: https://insights.sbomify.com/CVE-2012-6442/index.md)","id":"CVE-2012-6442","markdown":"https://insights.sbomify.com/CVE-2012-6442/index.md","name":"CVE-2012-6442","record":{"aliases":["GHSA-5v56-2w57-vj72"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Rockwell PLC","requires_auth":"none","summary":"An unauthorized remote attacker can send a valid CIP message to reset Rockwell Automation PLCs, causing a denial of service and communication disruption.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"compactlogix_controllers_firmware","vendor":"rockwellautomation"},{"product":"compactlogix_firmware","vendor":"rockwellautomation"},{"product":"controllogix_controllers_firmware","vendor":"rockwellautomation"},{"product":"controllogix_firmware","vendor":"rockwellautomation"},{"product":"ethernet\\/ip_firmware","vendor":"rockwellautomation"},{"product":"flex_i\\/o_ethernet\\/ip__firmware","vendor":"rockwellautomation"},{"product":"flexlogix_firmware","vendor":"rockwellautomation"},{"product":"guardlogix_controllers_firmware","vendor":"rockwellautomation"},{"product":"guardlogix_firmware","vendor":"rockwellautomation"},{"product":"micrologix_firmware","vendor":"rockwellautomation"},{"product":"softlogix_controllers_firmware","vendor":"rockwellautomation"},{"product":"softlogix_firmware","vendor":"rockwellautomation"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:C","version":"2.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"},{"id":"CWE-284","name":"Improper Access Control"}],"description":"When an affected product receives a valid CIP message from an unauthorized or unintended source to Port 2222/TCP, Port 2222/UDP, Port 44818/TCP, or Port 44818/UDP that instructs the product to reset, a DoS can occur.
