To exploit this vulnerability, the attacker must be a member of the admin group.\r\n\r 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. \r\n\r 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."}], "lastModified": "2024-01-25T17:15:26.757", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:cisco:network_services_orchestrator:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "C4BE422F-6650-403F-A560-EBA884C15FAF", "versionEndExcluding": "5.4.7", "versionStartIncluding": "3.3"}, {"criteria": "cpe:2.3:a:cisco:network_services_orchestrator:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "DB986CDE-4BCD-4A2D-99DB-BE900BA7F58C", "versionEndExcluding": "5.5.6", "versionStartIncluding": "5.5"}, {"criteria": "cpe:2.3:a:cisco:network_services_orchestrator:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "C5ABFC42-5078-4C13-A912-A83C96E72D05", "versionEndExcluding": "5.6.7", "versionStartIncluding": "5.6"}, {"criteria": "cpe:2.3:a:cisco:network_services_orchestrator:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "93EC0F10-628A-42D7-BC3D-4110FB6F9D53", "versionEndExcluding": "5.7.4", "versionStartIncluding": "5.7"}, {"criteria": "cpe:2.3:a:cisco:network_services_orchestrator:5.8:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "DAF61782-327C-4318-A4D1-DCB18CD835B0"}], "operator": "OR"}]}], "sourceIdentifier": "ykramarz@cisco.com"}
