A system crash and reboot can be achieved by submitting a long username in excess of 117 characters. The username triggers a buffer overflow in the main process controlling operation of the DVR system, rendering services unavailable during the reboot operation. A repeated attack affects availability as long as the attacker has network access to the device."}]}, "problemtype": {"problemtype_data": [{"description": [{"lang": "en", "value": "CWE-119"}]}]}, "data_version": "4.0", "CVE_data_meta": {"ID": "CVE-2019-12223", "ASSIGNER": "cve@mitre.org"}}, "impact": {"baseMetricV2": {"cvssV2": {"version": "2.0", "baseScore": 7.8, "accessVector": "NETWORK", "vectorString": "AV:N/AC:L/Au:N/C:N/I:N/A:C", "authentication": "NONE", "integrityImpact": "NONE", "accessComplexity": "LOW", "availabilityImpact": "COMPLETE", "confidentialityImpact": "NONE"}, "severity": "HIGH", "acInsufInfo": false, "impactScore": 6.9, "obtainAllPrivilege": false, "exploitabilityScore": 10.0, "obtainUserPrivilege": false, "obtainOtherPrivilege": false, "userInteractionRequired": false}, "baseMetricV3": {"cvssV3": {"scope": "UNCHANGED", "version": "3.0", "baseScore": 7.5, "attackVector": "NETWORK", "baseSeverity": "HIGH", "vectorString": "CVSS:3.0/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": "2019-09-05T15:15Z", "configurations": {"nodes": [{"children": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:o:hanwha-security:srn-472s_firmware:1.07_190502:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}]}, {"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:h:hanwha-security:srn-472s:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}]}], "operator": "AND", "cpe_match": []}, {"children": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:o:hanwha-security:srn-873s_firmware:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "2019-05-03"}]}, {"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:h:hanwha-security:srn-873s:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}]}], "operator": "AND", "cpe_match": []}, {"children": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:o:hanwha-security:srn-1673s_firmware:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "2019-05-03"}]}, {"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:h:hanwha-security:srn-1673s:-:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": false}]}], "operator": "AND", "cpe_match": []}], "CVE_data_version": "4.0"}, "lastModifiedDate": "2019-09-06T17:35Z"}
