An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2024-36980 exists.\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-2024-36980/ (Markdown: https://insights.sbomify.com/CVE-2024-36980/index.md)","id":"CVE-2024-36980","markdown":"https://insights.sbomify.com/CVE-2024-36980/index.md","name":"CVE-2024-36980","record":{"aliases":["GHSA-g38f-j3m7-3p88"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenPLC Runtime","requires_auth":"none","summary":"An attacker can cause a denial of service in OpenPLC Runtime by sending specially crafted EtherNet/IP requests to the PCCC parser.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"talos","cpe":[{"product":"openplc_v3_firmware","vendor":"openplcproject"}],"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-125","name":"Out-of-bounds Read"}],"description":"An out-of-bounds read vulnerability exists in the OpenPLC Runtime EtherNet/IP PCCC parser functionality of OpenPLC_v3 b4702061dc14d1024856f71b4543298d77007b88.
