Instead of sending a JWT token as a \"request\" parameter, the spec also supports specifying a URI from which to retrieve a JWT token from via the \"request_uri\" parameter. CXF was not validating the \"request_uri\" parameter (apart from ensuring it uses \"https) and was making a REST request to the parameter in the request to retrieve a token. This means that CXF was vulnerable to DDos attacks on the authorization server, as specified in section 10.4.1 of the spec. This issue affects Apache CXF versions prior to 3.4.3; Apache CXF versions prior to 3.3.10."}]}, "problemtype": {"problemtype_data": [{"description": [{"lang": "en", "value": "CWE-918"}]}]}, "data_version": "4.0", "CVE_data_meta": {"ID": "CVE-2021-22696", "ASSIGNER": "security@apache.org"}}, "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": "2021-04-02T10:15Z", "configurations": {"nodes": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:a:apache:cxf:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "3.4.3", "versionStartIncluding": "3.4.0"}, {"cpe23Uri": "cpe:2.3:a:apache:cxf:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "3.3.10"}]}, {"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:a:oracle:business_intelligence:12.2.1.3.0:*:*:*:enterprise:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:a:oracle:business_intelligence:12.2.1.4.0:*:*:*:enterprise:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:a:oracle:business_intelligence:5.5.0.0.0:*:*:*:enterprise:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:a:oracle:communications_session_route_manager:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndIncluding": "8.2.4", "versionStartIncluding": "8.0.0"}, {"cpe23Uri": "cpe:2.3:a:oracle:communications_session_report_manager:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndIncluding": "8.2.4.0", "versionStartIncluding": "8.0.0"}, {"cpe23Uri": "cpe:2.3:a:oracle:business_intelligence:5.9.0.0.0:*:*:*:enterprise:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:a:oracle:communications_element_manager:8.2.2:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}, {"cpe23Uri": "cpe:2.3:a:oracle:communications_diameter_intelligence_hub:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndIncluding": "8.1.0", "versionStartIncluding": "8.0.0"}, {"cpe23Uri": "cpe:2.3:a:oracle:communications_diameter_intelligence_hub:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndIncluding": "8.2.3", "versionStartIncluding": "8.2.0"}]}], "CVE_data_version": "4.0"}, "lastModifiedDate": "2022-05-12T14:36Z"}
