The attack causes the CPU to spike at 100%. nghttp2 v1.41.0 fixes this vulnerability. There is a workaround to this vulnerability. Implement nghttp2_on_frame_recv_callback callback, and if received frame is SETTINGS frame and the number of settings entries are large (e.g., > 32), then drop the connection."}]}, "problemtype": {"problemtype_data": [{"description": [{"lang": "en", "value": "CWE-707"}]}]}, "data_version": "4.0", "CVE_data_meta": {"ID": "CVE-2020-11080", "ASSIGNER": "security-advisories@github.com"}}, "impact": {"baseMetricV2": {"cvssV2": {"version": "2.0", "baseScore": 5.0, "accessVector": "NETWORK", "vectorString": "AV:N/AC:L/Au:N/C:N/I:N/A:P", "authentication": "NONE", "integrityImpact": "NONE", "accessComplexity": "LOW", "availabilityImpact": "PARTIAL", "confidentialityImpact": "NONE"}, "severity": "MEDIUM", "acInsufInfo": false, "impactScore": 2.9, "obtainAllPrivilege": false, "exploitabilityScore": 10.0, "obtainUserPrivilege": false, "obtainOtherPrivilege": false, "userInteractionRequired": false}, "baseMetricV3": {"cvssV3": {"scope": "UNCHANGED", "version": "3.1", "baseScore": 7.5, "attackVector": "NETWORK", "baseSeverity": "HIGH", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H", "integrityImpact": "NONE", "userInteraction": "NONE", "attackComplexity": "LOW", "availabilityImpact": "HIGH", "privilegesRequired": "NONE", "confidentialityImpact": "NONE"}, "impactScore": 3.6, "exploitabilityScore": 3.9}}, "publishedDate": "2020-06-03T23:15Z", "configurations": {"nodes": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:a:nghttp2:nghttp2:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "1.41.0"}]}, {"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:o:debian:debian_linux:9.0:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:o:debian:debian_linux:10.0:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}]}, {"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:o:opensuse:leap:15.1:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}]}, {"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:o:fedoraproject:fedora:31:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:o:fedoraproject:fedora:33:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}]}, {"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:a:oracle:enterprise_communications_broker:3.1.0:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:a:oracle:graalvm:19.3.2:*:*:*:enterprise:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:a:oracle:graalvm:20.1.0:*:*:*:enterprise:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:a:oracle:mysql:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndIncluding": "8.0.21", "versionStartIncluding": "8.0.0"}, {"cpe23Uri": "cpe:2.3:a:oracle:enterprise_communications_broker:3.2.0:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:a:oracle:mysql:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndIncluding": "7.6.15", "versionStartIncluding": "7.6.0"}, {"cpe23Uri": "cpe:2.3:a:oracle:mysql:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndIncluding": "7.5.19", "versionStartIncluding": "7.5.0"}, {"cpe23Uri": "cpe:2.3:a:oracle:mysql:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndIncluding": "7.4.29", "versionStartIncluding": "7.4.0"}, {"cpe23Uri": "cpe:2.3:a:oracle:mysql:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndIncluding": "7.3.30", "versionStartIncluding": "7.3.0"}, {"cpe23Uri": "cpe:2.3:a:oracle:banking_extensibility_workbench:14.4.0:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:a:oracle:banking_extensibility_workbench:14.3.0:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:a:oracle:blockchain_platform:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "21.1.2"}]}, {"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:a:nodejs:node.js:*:*:*:*:-:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndIncluding": "10.12.0", "versionStartIncluding": "10.0.0"}, {"cpe23Uri": "cpe:2.3:a:nodejs:node.js:*:*:*:*:lts:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "10.21.0", "versionStartIncluding": "10.13.0"}, {"cpe23Uri": "cpe:2.3:a:nodejs:node.js:*:*:*:*:-:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndIncluding": "12.12.0", "versionStartIncluding": "12.0.0"}, {"cpe23Uri": "cpe:2.3:a:nodejs:node.js:*:*:*:*:-:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndIncluding": "14.4.0", "versionStartIncluding": "14.0.0"}, {"cpe23Uri": "cpe:2.3:a:nodejs:node.js:*:*:*:*:lts:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "12.18.0", "versionStartIncluding": "12.13.0"}]}], "CVE_data_version": "4.0"}, "lastModifiedDate": "2022-08-29T20:41Z"}
