It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2021-27475 and fix it if it is affected.\n\nWhat it is: CVE-2021-27475 is a high-severity unsafe deserialization vulnerability in Rockwell Automation Connected Components Workbench, published on 23 Mar 2022. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-27475 in the wild and no public exploit code.\n\nAffected product: Rockwell Automation Connected Components Workbench. 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-2021-27475/ (Markdown: https://insights.sbomify.com/CVE-2021-27475/index.md)","id":"CVE-2021-27475","markdown":"https://insights.sbomify.com/CVE-2021-27475/index.md","name":"CVE-2021-27475","record":{"aliases":["GHSA-q489-3x56-hq57"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Industrial Automation Software","requires_auth":"none","summary":"Attackers can achieve remote code execution by tricking users into opening malicious serialized objects in Rockwell Automation Connected Components Workbench.","user_interaction":"required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"connected_components_workbench","vendor":"rockwellautomation"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"Rockwell Automation Connected Components Workbench v12.00.00 and prior does not limit the objects that can be deserialized.
