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-2024-21920 in the wild and no public exploit code.\n\nAffected product: Rockwell Automation Arena Simulation. 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-2024-21920/ (Markdown: https://insights.sbomify.com/CVE-2024-21920/index.md)","id":"CVE-2024-21920","markdown":"https://insights.sbomify.com/CVE-2024-21920/index.md","name":"CVE-2024-21920","record":{"aliases":["GHSA-xwx2-w5q7-pgf8"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["data_read","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Arena Simulation software","requires_auth":"none","summary":"A buffer overflow in Rockwell Arena Simulation allows attackers to read sensitive memory or crash the application by tricking users into opening malicious files.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Rockwell","cpe":[{"product":"arena","vendor":"rockwellautomation"}],"cvss":{"score":4.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"A memory buffer vulnerability in Rockwell Automation Arena Simulation could potentially let a threat actor read beyond the intended memory boundaries.
