Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2013-1838 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- nova (PyPI): affected all versions; fixed in 12.0.0a0\n- nova (PyPI): affected all versions; fixed in 12.0.0a0\n- nova (PyPI): affected all versions; fixed in 12.0.0a0\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-2013-1838/ (Markdown: https://insights.sbomify.com/CVE-2013-1838/index.md)","id":"CVE-2013-1838","markdown":"https://insights.sbomify.com/CVE-2013-1838/index.md","name":"CVE-2013-1838","record":{"aliases":["DEBIAN-CVE-2013-1838","GHSA-63fq-8fp9-vhwq","PYSEC-2013-44"],"analysis":{"component_type":"cloud_service","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenStack Compute","requires_auth":"low_privilege","summary":"Authenticated users can exhaust fixed IP quotas in OpenStack Compute, preventing new instance creation and causing denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"essex","vendor":"openstack"},{"product":"folsom","vendor":"openstack"},{"product":"grizzly","vendor":"openstack"}],"cvss":{"score":4,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:S/C:N/I:N/A:P","version":"2.0"},"cwes":[{"id":"CWE-399","name":null}],"description":"OpenStack Compute (Nova) Grizzly, Folsom (2012.2), and Essex (2012.1) does not properly implement a quota for fixed IPs, which allows remote authenticated users to cause a denial of service (resource exhaustion and failure to spawn new instances) via a large number of calls to the addFixedIp function.","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":"OpenStack Compute (Nova) Denial of service via a large number of calls to the addFixedIp function","id":"CVE-2013-1838","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":"canonical:ubuntu_linux","products":["canonical:ubuntu_linux"],"type":"denial_of_service","year":"2013"},"n_packages":3,"n_references":14,"next":{"headline":"Denial of service in n/a","id":"CVE-2013-1839"},"packages":[{"ecosystem":"PyPI","fixed":["12.0.0a0"],"introduced":["0"],"last_affected":[],"package":"nova","purl":null,"source":"GHSA-63fq-8fp9-vhwq"},{"ecosystem":"PyPI","fixed":["12.0.0a0"],"introduced":["0"],"last_affected":[],"package":"nova","purl":"pkg:pypi/nova","source":"GHSA-63fq-8fp9-vhwq"},{"ecosystem":"PyPI","fixed":["12.0.0a0"],"introduced":["0"],"last_affected":[],"package":"nova","purl":"pkg:pypi/nova","source":"PYSEC-2013-44"}],"prev":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2013-1837"},"products":["n/a"],"published":"2013-03-22","related":[{"cvss_score":9.8,"headline":"SaltStack Salt Authentication Bypass","id":"CVE-2020-11651","kev_date_added":"2021-11-03","published":"2020-04-30"},{"cvss_score":9.8,"headline":"OpenSMTPD Remote Code Execution","id":"CVE-2020-7247","kev_date_added":"2022-03-25","published":"2020-01-29"},{"cvss_score":9.8,"headline":"Exim Out-of-bounds Write","id":"CVE-2019-16928","kev_date_added":"2022-03-03","published":"2019-09-27"},{"cvss_score":9.8,"headline":"Exim Buffer Overflow","id":"CVE-2018-6789","kev_date_added":"2021-11-03","published":"2018-02-08"},{"cvss_score":9.8,"headline":"Oracle Java SE and Java SE Embedded Remote Code Execution","id":"CVE-2015-2590","kev_date_added":"2022-03-03","published":"2015-07-16"},{"cvss_score":9.8,"headline":"Oracle JRE Remote Code Execution","id":"CVE-2013-0422","kev_date_added":"2022-05-25","published":"2013-01-10"},{"cvss_score":9.8,"headline":"Oracle Java SE Runtime Environment (JRE) Arbitrary Code Execution","id":"CVE-2011-3544","kev_date_added":"2022-03-03","published":"2011-10-19"}],"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":"2024-08-06","vendors":["n/a"]},"summary":"Authenticated users can exhaust fixed IP quotas in OpenStack Compute, preventing new instance creation and causing denial of service.","url":"https://insights.sbomify.com/CVE-2013-1838/"}
