It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-47864 exists.\n\nAffected product: OSAS Traverse Extension. 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-2021-47864/ (Markdown: https://insights.sbomify.com/CVE-2021-47864/index.md)","id":"CVE-2021-47864","markdown":"https://insights.sbomify.com/CVE-2021-47864/index.md","name":"CVE-2021-47864","record":{"aliases":["GHSA-99mq-x342-ppq6"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"OSAS Traverse Extension","requires_auth":"low_privilege","summary":"Attackers can execute malicious code with LocalSystem privileges by exploiting an unquoted service path in OSAS Traverse Extension.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.5,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-428","name":"Unquoted Search Path or Element"}],"description":"OSAS Traverse Extension 11 contains an unquoted service path vulnerability in the TravExtensionHostSvc service running with LocalSystem privileges.
