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-2025-13823 in the wild and no public exploit code.\n\nAffected product: Rockwell Automation Micro820®, Micro850®,  Micro870®. 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-2025-13823/ (Markdown: https://insights.sbomify.com/CVE-2025-13823/index.md)","id":"CVE-2025-13823","markdown":"https://insights.sbomify.com/CVE-2025-13823/index.md","name":"CVE-2025-13823","record":{"aliases":["GHSA-wpv9-4fx9-263w"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"PLC controllers","requires_auth":"none","summary":"Attackers can cause Micro8 PLCs to enter a recoverable fault state by sending malformed IPv6 packets, requiring manual fault clearing.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Rockwell","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:A/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-1395","name":"Dependency on Vulnerable Third-Party Component"}],"description":"A security issue was found in the IPv6 stack in the Micro850 and Micro870 controllers when the controllers received multiple malformed packets during fuzzing.
