The vulnerability exists due to insufficient validation of certain elements with a Webex recording stored in either the Advanced Recording Format (ARF) or the Webex Recording Format (WRF). An attacker could exploit this vulnerability by sending a user a malicious ARF or WRF file through a link or email attachment and persuading the user to open the file with the affected software on the local system. A successful exploit could allow the attacker to cause the Webex player application to crash when trying to view the malicious file."},{"lang":"es","value":"Una vulnerabilidad en Cisco Webex Network Recording Player y Cisco Webex Player para Microsoft Windows, podría permitir a un atacante  causar un bloqueo del proceso resultando en una condición de Denegación de servicio (DoS) para la aplicación del reproductor en un sistema afectado. La vulnerabilidad se presenta debido a una comprobación insuficiente de determinados elementos con una grabación de Webex almacenada en el Advanced Recording Format (ARF) o en el Webex Recording Format (WRF). Un atacante podría explotar esta vulnerabilidad al enviar a un usuario un archivo ARF o WRF malicioso por medio de un enlace o archivo adjunto de correo electrónico y persuadiendo a un usuario de abrir el archivo con el software afectado en el sistema local. Una explotación con éxito podría permitir a un atacante causar que la aplicación del reproductor Webex se bloquee cuando tratan de visualizar el archivo malicioso."}],"metrics":{"cvssMetricV31":[{"source":"psirt@cisco.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L","baseScore":3.3,"baseSeverity":"LOW","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"REQUIRED","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"LOW"},"exploitabilityScore":1.8,"impactScore":1.4},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L","baseScore":3.3,"baseSeverity":"LOW","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"REQUIRED","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"LOW"},"exploitabilityScore":1.8,"impactScore":1.4}],"cvssMetricV2":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"2.0","vectorString":"AV:N/AC:M/Au:N/C:N/I:N/A:P","baseScore":4.3,"accessVector":"NETWORK","accessComplexity":"MEDIUM","authentication":"NONE","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"PARTIAL"},"baseSeverity":"MEDIUM","exploitabilityScore":8.6,"impactScore":2.9,"acInsufInfo":false,"obtainAllPrivilege":false,"obtainUserPrivilege":false,"obtainOtherPrivilege":false,"userInteractionRequired":true}]},"weaknesses":[{"source":"psirt@cisco.com","type":"Secondary","description":[{"lang":"en","value":"CWE-20"}]},{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"CWE-20"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:webex_player:*:*:*:*:*:windows:*:*","versionEndExcluding":"3.0","matchCriteriaId":"29AD80BF-4BD6-4B63-9DBE-5AAD219CC464"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:webex_player:3.0:-:*:*:*:windows:*:*","matchCriteriaId":"22E8B4CB-4380-4252-94FF-2FA9475E443C"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:webex_player:3.0:maintenance_release1:*:*:*:windows:*:*","matchCriteriaId":"C391D26A-B24C-4771-902A-6A8255ED9B49"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:webex_player:3.0:maintenance_release2:*:*:*:windows:*:*","matchCriteriaId":"0AFAA7F9-A6CE-4670-90D9-49DD60B01C79"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:webex_player:4.0:-:*:*:*:windows:*:*","matchCriteriaId":"173FD058-9353-4346-AEFE-2043FE05A05D"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:webex_player:4.0:maintenance_release1:*:*:*:windows:*:*","matchCriteriaId":"2F3E289B-1887-42BB-A3EE-5FE5BC9117AD"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:webex_player:4.0:maintenance_release2:*:*:*:windows:*:*","matchCriteriaId":"BD5D3C2F-8344-4281-9FC4-BAE8BD687A9A"}]}]},{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:webex_network_recording_player:*:*:*:*:*:*:*:*","versionEndExcluding":"3.0","matchCriteriaId":"3CD2D467-A1BA-41BC-9ABB-52A67961712C"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:webex_network_recording_player:3.0:-:*:*:*:*:*:*","matchCriteriaId":"F802539A-BF0D-4178-AA6F-39186ADA2940"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:webex_network_recording_player:3.0:maintenance_release1:*:*:*:*:*:*","matchCriteriaId":"88A0132D-146E-40D5-AD93-9392878A9703"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:webex_network_recording_player:3.0:maintenance_release2:*:*:*:*:*:*","matchCriteriaId":"5D63BB12-E138-4686-B115-C8935418269C"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:webex_network_recording_player:4.0:-:*:*:*:*:*:*","matchCriteriaId":"9C216B45-3F47-4271-8C86-167CCFE6A67A"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:webex_network_recording_player:4.0:maintenance_release1:*:*:*:*:*:*","matchCriteriaId":"56CB908D-A71E-4CE4-8692-9439585CC7D5"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:webex_network_recording_player:4.0:maintenance_release2:*:*:*:*:*:*","matchCriteriaId":"207BE80A-EFB5-4318-B03D-6CC37633CCED"}]}]}],"references":[{"url":"https://quickview.cloudapps.cisco.com/quickview/bug/CSCvs98259","source":"psirt@cisco.com","tags":["Vendor Advisory"]},{"url":"https://quickview.cloudapps.cisco.com/quickview/bug/CSCvs98259","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Vendor Advisory"]}]}}]}
