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-2020-8634 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2020-8634/ (Markdown: https://insights.sbomify.com/CVE-2020-8634/index.md)","id":"CVE-2020-8634","markdown":"https://insights.sbomify.com/CVE-2020-8634/index.md","name":"CVE-2020-8634","record":{"aliases":["GHSA-h98j-87f6-38m2"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Wing FTP Server","requires_auth":"low_privilege","summary":"Low-privilege users can escalate to root by editing sensitive system files via the HTTP interface due to insecure file permissions.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"wing_ftp_server","vendor":"wftpserver"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-281","name":"Improper Preservation of Permissions"}],"description":"Wing FTP Server v6.2.3 for Linux, macOS, and Solaris sets insecure permissions on files modified within the HTTP file management interface, resulting in files being saved with world-readable and world-writable permissions.
