This vulnerability is due to improper validation of parameters that are sent to a CLI command within the restricted shell. An attacker could exploit this vulnerability by logging in to the device and issuing certain CLI commands. A successful exploit could allow the attacker to identify file directories on the affected device and write arbitrary files to the file system on the affected device. To exploit this vulnerability, the attacker must be an authenticated shell user."},{"lang":"es","value":"Una vulnerabilidad en el shell restringido de Cisco Evolved Programmable Network (EPN) Manager, Cisco Identity Services Engine (ISE) y Cisco Prime Infrastructure, podría permitir a un atacante autenticado local identificar directorios y escribir archivos arbitrarios en el sistema de archivos. Esta vulnerabilidad es debido a una comprobación inapropiada de los parámetros que son enviados hacia un comando de CLI dentro del shell restringido. Un atacante podría explotar esta vulnerabilidad iniciando sesión en el dispositivo y emitiendo determinados comandos de CLI. Una explotación con éxito podría permitir al atacante identificar directorios de archivos en el dispositivo afectado y escribir archivos arbitrarios en el sistema de archivos del dispositivo afectado. Para explotar esta vulnerabilidad, el atacante debe ser un usuario de shell autenticado"}],"metrics":{"cvssMetricV31":[{"source":"psirt@cisco.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","baseScore":4.4,"baseSeverity":"MEDIUM","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"LOW","availabilityImpact":"NONE"},"exploitabilityScore":1.8,"impactScore":2.5},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:N","baseScore":3.4,"baseSeverity":"LOW","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"HIGH","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"LOW","availabilityImpact":"NONE"},"exploitabilityScore":0.8,"impactScore":2.5}],"cvssMetricV2":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"2.0","vectorString":"AV:L/AC:L/Au:N/C:P/I:P/A:N","baseScore":3.6,"accessVector":"LOCAL","accessComplexity":"LOW","authentication":"NONE","confidentialityImpact":"PARTIAL","integrityImpact":"PARTIAL","availabilityImpact":"NONE"},"baseSeverity":"LOW","exploitabilityScore":3.9,"impactScore":4.9,"acInsufInfo":false,"obtainAllPrivilege":false,"obtainUserPrivilege":false,"obtainOtherPrivilege":false,"userInteractionRequired":false}]},"weaknesses":[{"source":"psirt@cisco.com","type":"Secondary","description":[{"lang":"en","value":"CWE-73"}]},{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"CWE-610"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:evolved_programmable_network_manager:*:*:*:*:*:*:*:*","versionEndExcluding":"5.0.1","matchCriteriaId":"A539891B-EEAC-4909-98A9-ECD882FCAC1A"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:identity_services_engine:*:*:*:*:*:*:*:*","versionEndExcluding":"2.7.0","matchCriteriaId":"4D859076-BAB5-41B8-860E-646FE4E37264"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:identity_services_engine:2.7.0:-:*:*:*:*:*:*","matchCriteriaId":"1F22FABF-2831-4895-B0A9-283B98398F43"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:identity_services_engine:2.7.0:patch2:*:*:*:*:*:*","matchCriteriaId":"2887A2C0-BADA-41D3-AA6A-F10BC58AA7F9"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:identity_services_engine:3.0.0:-:*:*:*:*:*:*","matchCriteriaId":"A1063044-BCD7-487F-9880-141C30547E36"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:identity_services_engine:3.0.0:patch1:*:*:*:*:*:*","matchCriteriaId":"DA42E65A-7207-48B8-BE1B-0B352201BC09"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:prime_infrastructure:*:*:*:*:*:*:*:*","versionEndExcluding":"3.8.1","matchCriteriaId":"4D874EC8-DCD1-4140-AB45-6320F87BE37F"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:prime_infrastructure:3.8.1:-:*:*:*:*:*:*","matchCriteriaId":"608240CD-CD6C-42A3-9590-7F37B35EDC53"}]}]}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ade-xcvAQEOZ","source":"psirt@cisco.com","tags":["Vendor Advisory"]},{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ade-xcvAQEOZ","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Vendor Advisory"]}]}}]}
