An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2023-3596 and fix it if it is affected.\n\nWhat it is: CVE-2023-3596 is a high-severity denial of service vulnerability in Rockwell Automation 1756-EN4TR Series A, published on 12 Jul 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-2023-3596 in the wild and no public exploit code.\n\nAffected product: Rockwell Automation 1756-EN4TR Series A. 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-2023-3596/ (Markdown: https://insights.sbomify.com/CVE-2023-3596/index.md)","id":"CVE-2023-3596","markdown":"https://insights.sbomify.com/CVE-2023-3596/index.md","name":"CVE-2023-3596","record":{"aliases":["GHSA-xvq9-c88q-jf5x"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial Ethernet Module","requires_auth":"none","summary":"A malicious user can cause a denial of service on Rockwell Automation ControlLogix communication modules by sending crafted CIP messages.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Rockwell","cpe":[{"product":"1756-en4tr_firmware","vendor":"rockwellautomation"},{"product":"1756-en4trk_firmware","vendor":"rockwellautomation"},{"product":"1756-en4trxt_firmware","vendor":"rockwellautomation"}],"cvss":{"score":7.5,"severity":"high","source":"cna","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-787","name":"Out-of-bounds Write"}],"description":"Where this vulnerability exists in the Rockwell Automation 1756-EN4* Ethernet/IP communication products, it could allow a malicious user to cause a denial of service by asserting the target system through maliciously crafted CIP messages.","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":"Rockwell Automation Allen-Bradley ControlLogix Communication Modules vulnerable to Denial of Service","id":"CVE-2023-3596","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Keycloak: secondary factor bypass in step-up authentication","id":"CVE-2023-3597"},"packages":[],"prev":{"headline":"Rockwell Automation ControlLogix Communication Modules Vulnerable to Remote Code Execution","id":"CVE-2023-3595"},"products":["1756-EN4TR Series A","1756-EN4TRK Series A","1756-EN4TRXT Series A\t"],"published":"2023-07-12","related":[{"cvss_score":8.7,"headline":"Logix Controllers Vulnerable to Denial-of-Service Vulnerability","id":"CVE-2024-8626","kev_date_added":null,"published":"2024-10-08"},{"cvss_score":8.6,"headline":"Rockwell Automation ControlLogix and GaurdLogix Vulnerable to Major Nonrecoverable Fault Due to Invalid Header Value","id":"CVE-2024-3493","kev_date_added":null,"published":"2024-04-15"}],"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":"2024-11-07","vendors":["Rockwell Automation"]},"summary":"A malicious user can cause a denial of service on Rockwell Automation ControlLogix communication modules by sending crafted CIP messages.","url":"https://insights.sbomify.com/CVE-2023-3596/"}
