It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-54811 in the wild and no public exploit code.\n\nAffected product: OpenPLC_V3. 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-2025-54811/ (Markdown: https://insights.sbomify.com/CVE-2025-54811/index.md)","id":"CVE-2025-54811","markdown":"https://insights.sbomify.com/CVE-2025-54811/index.md","name":"CVE-2025-54811","record":{"aliases":["GHSA-v57j-j5hj-cgf3"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"OpenPLC runtime","requires_auth":"none","summary":"Remote unauthenticated attackers can crash the OpenPLC runtime by triggering a specific server loop condition, halting automation logic.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:N/SC:N/SI:N/SA:H","version":"4.0"},"cwes":[{"id":"CWE-758","name":"Reliance on Undefined, Unspecified, or Implementation-Defined Behavior"}],"description":"OpenPLC_V3 has a vulnerability in the enipThread function that occurs due to the lack of a return value. This leads to a crash when the server loop ends and execution hits an illegal ud2 instruction. This issue can be triggered remotely without authentication by starting the same server multiple times or if the server exits unexpectedly. The vulnerability allows an attacker to cause a Denial of Service (DoS) against the PLC runtime, stopping any PC started remotely without authentication. This results in the PLC process crashing and halting all automation or control logic managed by OpenPLC.","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":"OpenPLC_V3","id":"CVE-2025-54811","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2025"},"n_packages":0,"n_references":2,"next":{"headline":"Apache Log4cxx: Improper HTML escaping in HTMLLayout","id":"CVE-2025-54812"},"packages":[],"prev":{"headline":"Cognex In-Sight Explorer and In-Sight Camera Firmware Authentication Bypass by Capture-replay","id":"CVE-2025-54810"},"products":["OpenPLC_V3"],"published":"2025-10-01","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-10-02","vendors":["OpenPLC_V3"]},"summary":"Remote unauthenticated attackers can crash the OpenPLC runtime by triggering a specific server loop condition, halting automation logic.","url":"https://insights.sbomify.com/CVE-2025-54811/"}
