The vulnerability is due to incomplete input validation of path and file names of a DLL file before it is loaded. An attacker could exploit this vulnerability by creating a malicious DLL file and installing it in a specific system directory. A successful exploit could allow the attacker to execute commands on the underlying Microsoft Windows host with privileges equivalent to the SYSTEM account. An attacker would need valid user credentials to exploit this vulnerability."},{"lang":"es","value":"Una vulnerabilidad de ruta de búsqueda no fiable (también conocida como precarga de DLL) en el software Cisco Network Academy Packet podría permitir que un atacante local autenticado ejecute código arbitrario mediante el secuestro de DLL si un usuario local con privilegios administrativos ejecuta el instalador en el directorio de trabajo actual en donde un atacante ha situado un DLL manipulado. La vulnerabilidad se debe a una validación incompleta de los nombres de ruta y archivo de un archivo DLL antes de que se carguen. Un atacante podría explotar esta vulnerabilidad creando un archivo DLL malicioso e instalándolo en un directorio del sistema específico. Un exploit con éxito podría permitir que el atacante ejecute comandos en el host subyacente de Microsoft Windows con privilegios equivalentes a los de una cuenta SYSTEM. Un atacante necesitaría credenciales de usuario válidas para explotar esta vulnerabilidad."}],"metrics":{"cvssMetricV30":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.0","vectorString":"CVSS:3.0/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","baseScore":6.7,"baseSeverity":"MEDIUM","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"HIGH","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":0.8,"impactScore":5.9}],"cvssMetricV2":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"2.0","vectorString":"AV:L/AC:L/Au:N/C:C/I:C/A:C","baseScore":7.2,"accessVector":"LOCAL","accessComplexity":"LOW","authentication":"NONE","confidentialityImpact":"COMPLETE","integrityImpact":"COMPLETE","availabilityImpact":"COMPLETE"},"baseSeverity":"HIGH","exploitabilityScore":3.9,"impactScore":10.0,"acInsufInfo":false,"obtainAllPrivilege":false,"obtainUserPrivilege":false,"obtainOtherPrivilege":false,"userInteractionRequired":false}]},"weaknesses":[{"source":"psirt@cisco.com","type":"Secondary","description":[{"lang":"en","value":"CWE-427"}]},{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"CWE-20"},{"lang":"en","value":"CWE-426"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:packet_tracer:*:*:*:*:*:*:*:*","matchCriteriaId":"BA68F45D-747E-492F-9E48-7F8AFA14B89D"}]}]}],"references":[{"url":"http://www.securityfocus.com/bid/101858","source":"psirt@cisco.com","tags":["Third Party Advisory","VDB Entry"]},{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20171115-cpt","source":"psirt@cisco.com","tags":["Vendor Advisory"]},{"url":"http://www.securityfocus.com/bid/101858","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Third Party Advisory","VDB Entry"]},{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20171115-cpt","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Vendor Advisory"]}]}}]}
