This vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by sending a crafted HTTP request that contains directory traversal character sequences to an affected system. A successful exploit could allow the attacker to access sensitive files on the affected system."},{"lang":"es","value":"Una vulnerabilidad en la interfaz de administración basada en la web de Cisco Unified Communications Manager (Unified CM), Cisco Unified Communications Manager Session Management Edition (Unified CM SME), Cisco Unified Communications Manager IM & Presence Service (Unified CM IM&P) y Cisco Unity Connection podría permitir a un atacante remoto autenticado acceder a datos confidenciales en un dispositivo afectado. Esta vulnerabilidad es debido a que la interfaz de administración basada en la web no comprueba correctamente las entradas proporcionadas por el usuario. Un atacante podría explotar esta vulnerabilidad mediante el envío de una petición HTTP diseñada que contenga secuencias de caracteres de salto de directorio en un sistema afectado. Una explotación con éxito podría permitir al atacante acceder a archivos confidenciales en el sistema afectado"}],"metrics":{"cvssMetricV31":[{"source":"psirt@cisco.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","baseScore":4.3,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"NONE","availabilityImpact":"NONE"},"exploitabilityScore":2.8,"impactScore":1.4},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","baseScore":4.3,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"NONE","availabilityImpact":"NONE"},"exploitabilityScore":2.8,"impactScore":1.4}],"cvssMetricV2":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"2.0","vectorString":"AV:N/AC:L/Au:S/C:P/I:N/A:N","baseScore":4.0,"accessVector":"NETWORK","accessComplexity":"LOW","authentication":"SINGLE","confidentialityImpact":"PARTIAL","integrityImpact":"NONE","availabilityImpact":"NONE"},"baseSeverity":"MEDIUM","exploitabilityScore":8.0,"impactScore":2.9,"acInsufInfo":false,"obtainAllPrivilege":false,"obtainUserPrivilege":false,"obtainOtherPrivilege":false,"userInteractionRequired":false}]},"weaknesses":[{"source":"psirt@cisco.com","type":"Secondary","description":[{"lang":"en","value":"CWE-22"}]},{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"CWE-22"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:unified_communications_manager:*:*:*:*:*:*:*:*","versionEndExcluding":"14su1","matchCriteriaId":"51C88F69-17A2-4DA3-9831-53BE4690B678"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:unified_communications_manager:*:*:*:*:session_management:*:*:*","versionEndExcluding":"14su1","matchCriteriaId":"C03E4F7D-0C94-46A5-8BC4-359931FCCE16"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:unified_communications_manager_im_and_presence_service:*:*:*:*:*:*:*:*","versionEndExcluding":"14su1","matchCriteriaId":"B9C2976D-CDF4-44C6-9EE7-09A76D56F4A5"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:unity_connection:*:*:*:*:*:*:*:*","versionEndExcluding":"14su1","matchCriteriaId":"249F488B-B26E-437F-A450-D57BA3E18E5E"}]}]}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-cucm-path-trav-dKCvktvO","source":"psirt@cisco.com","tags":["Patch","Vendor Advisory"]},{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-cucm-path-trav-dKCvktvO","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch","Vendor Advisory"]}]}}]}
