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-2020-27004 in the wild and no public exploit code.\n\nAffected product: Siemens Jt2go. 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-2020-27004/ (Markdown: https://insights.sbomify.com/CVE-2020-27004/index.md)","id":"CVE-2020-27004","markdown":"https://insights.sbomify.com/CVE-2020-27004/index.md","name":"CVE-2020-27004","record":{"aliases":["GHSA-vf7v-wqw9-gv37"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Siemens visualization software","requires_auth":"none","summary":"An attacker can read sensitive memory data by exploiting a buffer over-read vulnerability in JT2Go and Teamcenter Visualization when parsing CGM files.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"jt2go","vendor":"siemens"},{"product":"teamcenter_visualization","vendor":"siemens"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"A vulnerability has been identified in JT2Go (All versions \u003c V13.1.0.1), Teamcenter Visualization (All versions \u003c V13.1.0.1).
