To exploit this vulnerability, the attacker would need valid credentials on the system. The vulnerability is due to insufficient validation of directory search paths at run time. An attacker could exploit this vulnerability by placing a malicious DLL file on an affected system. A successful exploit could allow the attacker to execute arbitrary code with SYSTEM privileges."},{"lang":"es","value":"Una vulnerabilidad en el mecanismo de carga de la dynamic link library (DLL) en Cisco Advanced Malware Protection (AMP) para Endpoints Windows Connector, ClamAV para Windows e Immunet, podría permitir a un atacante local autenticado llevar a cabo un ataque de secuestro DLL en un sistema Windows afectado. Para explotar esta vulnerabilidad, el atacante necesitaría credenciales válidas en el sistema. La vulnerabilidad es debido a una comprobación insuficiente de las rutas de búsqueda de directorios en tiempo de ejecución. Un atacante podría explotar esta vulnerabilidad al colocar un archivo DLL malicioso en un sistema afectado. Una explotación con éxito podría permitir al atacante ejecutar código arbitrario con privilegios SYSTEM"}],"metrics":{"cvssMetricV31":[{"source":"psirt@cisco.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","baseScore":7.0,"baseSeverity":"HIGH","attackVector":"LOCAL","attackComplexity":"HIGH","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":1.0,"impactScore":5.9},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","baseScore":7.8,"baseSeverity":"HIGH","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":1.8,"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"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:advanced_malware_protection_for_endpoints:*:*:*:*:*:windows:*:*","versionEndExcluding":"7.3.15","matchCriteriaId":"9DC181C7-11E3-4AA8-8E4B-43F1C0D3F73E"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:clamav:*:*:*:*:*:windows:*:*","versionEndExcluding":"0.103.2","matchCriteriaId":"5BBCAAEA-C3BC-41CB-9395-22309FDF80DE"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:immunet:*:*:*:*:*:windows:*:*","versionEndExcluding":"7.4.0","matchCriteriaId":"F56DFDB8-3196-4BDC-9254-66849E3729E8"}]}]}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-amp-imm-dll-tu79hvkO","source":"psirt@cisco.com","tags":["Vendor Advisory"]},{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-amp-imm-dll-tu79hvkO","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Vendor Advisory"]}]}}]}
