Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2017-16239 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- nova (PyPI): affected from 14.0.0; fixed in 14.0.10, 15.0.8, 16.0.3\n- nova (PyPI): affected from 14.0.0; fixed in 14.0.10\n- nova (PyPI): affected from 14.0.0; fixed in 14.0.10\n- nova (PyPI): affected from 15.0.0; fixed in 15.0.8\n- nova (PyPI): affected from 15.0.0; fixed in 15.0.8\n- nova (PyPI): affected from 16.0.0; fixed in 16.0.3\n- nova (PyPI): affected from 16.0.0; fixed in 16.0.3\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-2017-16239/ (Markdown: https://insights.sbomify.com/CVE-2017-16239/index.md)","id":"CVE-2017-16239","markdown":"https://insights.sbomify.com/CVE-2017-16239/index.md","name":"CVE-2017-16239","record":{"aliases":["DEBIAN-CVE-2017-16239","DSA-4056-1","GHSA-w2wf-cgwh-vpqg","PYSEC-2026-694","RHSA-2018:0241","RHSA-2018:0314","RHSA-2018:0369","SUSE-SU-2017:3080-1","UBUNTU-CVE-2017-16239"],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"OpenStack Nova","requires_auth":"low_privilege","summary":"Authenticated users can bypass scheduler filters by rebuilding instances, potentially violating isolation policies in OpenStack Nova deployments.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"nova","vendor":"openstack"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","version":"3.0"},"cwes":[],"description":"In OpenStack Nova through 14.0.9, 15.x through 15.0.7, and 16.x through 16.0.2, by rebuilding an instance, an authenticated user may be able to circumvent the Filter Scheduler bypassing imposed filters (for example, the ImagePropertiesFilter or the IsolatedHostsFilter).
