The vulnerability is due to incorrect validation of the HTTP header of a request that is sent to the NX-API. An attacker could exploit this vulnerability by sending a crafted HTTP request to the NX-API on an affected device. A successful exploit could allow the attacker to cause a denial of service (DoS) condition in the NX-API service; however, the Cisco NX-OS device itself would still be available and passing network traffic. Note: The NX-API feature is disabled by default."}]}, "problemtype": {"problemtype_data": [{"description": [{"lang": "en", "value": "CWE-20"}]}]}, "data_version": "4.0", "CVE_data_meta": {"ID": "CVE-2020-3170", "ASSIGNER": "psirt@cisco.com"}}, "impact": {"baseMetricV2": {"cvssV2": {"version": "2.0", "baseScore": 4.3, "accessVector": "NETWORK", "vectorString": "AV:N/AC:M/Au:N/C:N/I:N/A:P", "authentication": "NONE", "integrityImpact": "NONE", "accessComplexity": "MEDIUM", "availabilityImpact": "PARTIAL", "confidentialityImpact": "NONE"}, "severity": "MEDIUM", "acInsufInfo": false, "impactScore": 2.9, "obtainAllPrivilege": false, "exploitabilityScore": 8.6, "obtainUserPrivilege": false, "obtainOtherPrivilege": false, "userInteractionRequired": false}, "baseMetricV3": {"cvssV3": {"scope": "UNCHANGED", "version": "3.1", "baseScore": 5.3, "attackVector": "NETWORK", "baseSeverity": "MEDIUM", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L", "integrityImpact": "NONE", "userInteraction": "NONE", "attackComplexity": "LOW", "availabilityImpact": "LOW", "privilegesRequired": "NONE", "confidentialityImpact": "NONE"}, "impactScore": 1.4, "exploitabilityScore": 3.9}}, "publishedDate": "2020-02-26T17:15Z", "configurations": {"nodes": [{"children": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:o:cisco:nx-os:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "8.4\\(1\\)"}]}, {"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:h:cisco:mds_9132t:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:cisco:mds_9148s:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:cisco:mds_9148t:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:cisco:mds_9216:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:cisco:mds_9216a:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:cisco:mds_9216i:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:cisco:mds_9222i:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:cisco:mds_9506:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:cisco:mds_9509:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:cisco:mds_9513:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:cisco:mds_9706:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:cisco:mds_9718:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:cisco:mds_9710:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}]}], "operator": "AND", "cpe_match": []}, {"children": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:o:cisco:nx-os:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "8.2\\(5\\)"}]}, {"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:h:cisco:nexus_7000:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}, {"cpe23Uri": "cpe:2.3:h:cisco:nexus_7700:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}]}], "operator": "AND", "cpe_match": []}], "CVE_data_version": "4.0"}, "lastModifiedDate": "2020-03-03T21:19Z"}
