An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-39479 in the wild and no public exploit code.\n\nAffected product: Softing Secure Integration Server. 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-2023-39479/ (Markdown: https://insights.sbomify.com/CVE-2023-39479/index.md)","id":"CVE-2023-39479","markdown":"https://insights.sbomify.com/CVE-2023-39479/index.md","name":"CVE-2023-39479","record":{"aliases":["GHSA-xc4w-62f4-xjvv"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_modify","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"OPC UA Gateway","requires_auth":"high_privilege","summary":"Remote attackers can bypass authentication to create directories on the filesystem, potentially leading to root code execution.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"zdi","cpe":[{"product":"secure_integration_server","vendor":"softing"}],"cvss":{"score":6.6,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-552","name":"Files or Directories Accessible to External Parties"}],"description":"Softing Secure Integration Server OPC UA Gateway Directory Creation Vulnerability.
