To exploit this vulnerability, the attacker must be a member of the admin group. This vulnerability exists because user-supplied input is not properly validated when NETCONF is used to upload packages to an affected device. An attacker could exploit this vulnerability by uploading a specially crafted package file. A successful exploit could allow the attacker to write crafted files to arbitrary locations on the filesystem or delete arbitrary files from the filesystem of an affected device, resulting in a DoS condition. Note: By default, during install, Cisco NSO will be set up to run as the root user unless the --run-as-user option is used."}]}, "problemtype": {"problemtype_data": [{"description": [{"lang": "en", "value": "CWE-434"}]}]}, "data_version": "4.0", "CVE_data_meta": {"ID": "CVE-2023-20040", "ASSIGNER": "psirt@cisco.com"}}, "impact": {"baseMetricV3": {"cvssV3": {"scope": "UNCHANGED", "version": "3.1", "baseScore": 5.5, "attackVector": "NETWORK", "baseSeverity": "MEDIUM", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:H", "integrityImpact": "LOW", "userInteraction": "NONE", "attackComplexity": "LOW", "availabilityImpact": "HIGH", "privilegesRequired": "HIGH", "confidentialityImpact": "NONE"}, "impactScore": 4.2, "exploitabilityScore": 1.2}}, "publishedDate": "2023-01-20T07:15Z", "configurations": {"nodes": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:a:cisco:network_services_orchestrator:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "5.7.4", "versionStartIncluding": "5.7"}, {"cpe23Uri": "cpe:2.3:a:cisco:network_services_orchestrator:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "5.6.7", "versionStartIncluding": "5.6"}, {"cpe23Uri": "cpe:2.3:a:cisco:network_services_orchestrator:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "5.5.6", "versionStartIncluding": "5.5"}, {"cpe23Uri": "cpe:2.3:a:cisco:network_services_orchestrator:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndExcluding": "5.4.7", "versionStartIncluding": "3.3"}, {"cpe23Uri": "cpe:2.3:a:cisco:network_services_orchestrator:5.8:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true}]}], "CVE_data_version": "4.0"}, "lastModifiedDate": "2023-02-01T02:43Z"}
