An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-21822 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- nvflare (PyPI): affected all versions; fixed in 2.0.16\n- nvflare (PyPI): affected all versions; fixed in 2.0.16\n- nvflare (PyPI): affected all versions; fixed in 2.0.16\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-2022-21822/ (Markdown: https://insights.sbomify.com/CVE-2022-21822/index.md)","id":"CVE-2022-21822","markdown":"https://insights.sbomify.com/CVE-2022-21822/index.md","name":"CVE-2022-21822","record":{"aliases":["GHSA-jx8f-cpx7-fv47","PYSEC-2026-695"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"NVIDIA FLARE library","requires_auth":"none","summary":"An unauthenticated attacker can cause resource exhaustion in the NVIDIA FLARE admin interface, leading to system unavailability.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"nvidia","cpe":[{"product":"federated_learning_application_runtime_environment","vendor":"nvidia"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"NVIDIA FLARE contains a vulnerability in the admin interface, where an un-authorized attacker can cause Allocation of Resources Without Limits or Throttling, which may lead to cause system unavailable.","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Allocation of Resources Without Limits or Throttling in nvflare","id":"CVE-2022-21822","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"denial_of_service","year":"2022"},"n_packages":3,"n_references":1,"next":{"headline":"Information disclosure in Ivanti Workspace Control","id":"CVE-2022-21823"},"packages":[{"ecosystem":"PyPI","fixed":["2.0.16"],"introduced":["0"],"last_affected":[],"package":"nvflare","purl":null,"source":"GHSA-jx8f-cpx7-fv47"},{"ecosystem":"PyPI","fixed":["2.0.16"],"introduced":["0"],"last_affected":[],"package":"nvflare","purl":"pkg:pypi/nvflare","source":"GHSA-jx8f-cpx7-fv47"},{"ecosystem":"PyPI","fixed":["2.0.16"],"introduced":["0"],"last_affected":[],"package":"nvflare","purl":"pkg:pypi/nvflare","source":"PYSEC-2026-695"}],"prev":{"headline":"Integer overflow in NVIDIA CUDA Toolkit","id":"CVE-2022-21821"},"products":["NVIDIA FLARE"],"published":"2022-03-17","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["NVIDIA"]},"summary":"An unauthenticated attacker can cause resource exhaustion in the NVIDIA FLARE admin interface, leading to system unavailability.","url":"https://insights.sbomify.com/CVE-2022-21822/"}
