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."}],"affected":[{"vendor":"Cisco","product":"Cisco Network Services Orchestrator","versions":[{"version":"4.7.3","status":"affected"}]}],"problemTypes":[{"descriptions":[{"lang":"en","description":"Relative Path Traversal","type":"cwe","cweId":"CWE-23"}]}],"references":[{"url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-nso-path-trvsl-zjBeMkZg","name":"cisco-sa-nso-path-trvsl-zjBeMkZg"}],"metrics":[{"format":"cvssV3_1","cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:H","baseScore":5.5,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"HIGH","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"LOW","availabilityImpact":"HIGH"}}],"exploits":[{"lang":"en","value":"The Cisco PSIRT is not aware of any public announcements or malicious use of the vulnerability that is described in this advisory."}],"source":{"advisory":"cisco-sa-nso-path-trvsl-zjBeMkZg","discovery":"INTERNAL","defects":["CSCwb11065"]}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T08:57:35.576Z"},"title":"CVE Program Container","references":[{"url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-nso-path-trvsl-zjBeMkZg","name":"cisco-sa-nso-path-trvsl-zjBeMkZg","tags":["x_transferred"]}]}]}}
