Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-17376 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- nova (PyPI): affected all versions; no fix listed\n- nova (PyPI): affected all versions; no fix listed\n- nova (PyPI): affected all versions; fixed in 19.3.1, 20.3.1, 21.1.0\n- nova (PyPI): affected all versions; fixed in 19.3.1\n- nova (PyPI): affected all versions; fixed in 19.3.1\n- nova (PyPI): affected from 20.0.0; fixed in 20.3.1\n- nova (PyPI): affected from 20.0.0; fixed in 20.3.1\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-2020-17376/ (Markdown: https://insights.sbomify.com/CVE-2020-17376/index.md)","id":"CVE-2020-17376","markdown":"https://insights.sbomify.com/CVE-2020-17376/index.md","name":"CVE-2020-17376","record":{"aliases":["DEBIAN-CVE-2020-17376","GHSA-c7w7-9c85-4qxv","PYSEC-2020-243","RHSA-2020:3702","RHSA-2020:3704","RHSA-2020:3706","RHSA-2020:3708","RHSA-2020:3711","UBUNTU-CVE-2020-17376"],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"OpenStack Nova","requires_auth":"low_privilege","summary":"Attackers can access destination host devices via soft reboot after live migration, potentially reading or modifying data on shared paths.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"nova","vendor":"openstack"}],"cvss":{"score":8.3,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:L","version":"3.1"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"An issue was discovered in Guest.migrate in virt/libvirt/guest.py in OpenStack Nova before 19.3.1, 20.x before 20.3.1, and 21.0.0.
