To exploit this vulnerability, the attacker would need to have valid credentials on the device. The vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by sending one or more crafted IPC messages to the AnyConnect process on an affected device. A successful exploit could allow the attacker to stop the AnyConnect process, causing a DoS condition on the device. Note: The process under attack will automatically restart so no action is needed by the user or admin."},{"lang":"es","value":"Una vulnerabilidad en el canal de comunicación entre procesos (IPC) de Cisco AnyConnect Secure Mobility Client podría permitir que un atacante local autenticado causar una condición de denegación de servicio (DoS) en un dispositivo afectado. Para explotar esta vulnerabilidad, el atacante debería tener credenciales válidas en el dispositivo. La vulnerabilidad es debido a una comprobación insuficiente de la entrada suministrada por el usuario. Un atacante podría explotar esta vulnerabilidad mediante el envío de uno o más mensajes IPC diseñados al proceso AnyConnect en un dispositivo afectado. Una explotación con éxito podría permitir al atacante detener el proceso de AnyConnect, causando una condición de DoS en el dispositivo. Nota: El proceso bajo ataque se reiniciará automáticamente, por lo que el usuario o el administrador no deben realizar ninguna acción"}],"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:N/I:N/A:H","baseScore":5.5,"baseSeverity":"MEDIUM","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":1.8,"impactScore":3.6},{"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:N/I:N/A:H","baseScore":5.5,"baseSeverity":"MEDIUM","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":1.8,"impactScore":3.6}],"cvssMetricV2":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"2.0","vectorString":"AV:L/AC:L/Au:N/C:N/I:N/A:C","baseScore":4.9,"accessVector":"LOCAL","accessComplexity":"LOW","authentication":"NONE","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"COMPLETE"},"baseSeverity":"MEDIUM","exploitabilityScore":3.9,"impactScore":6.9,"acInsufInfo":false,"obtainAllPrivilege":false,"obtainUserPrivilege":false,"obtainOtherPrivilege":false,"userInteractionRequired":false}]},"weaknesses":[{"source":"psirt@cisco.com","type":"Secondary","description":[{"lang":"en","value":"CWE-20"}]}],"configurations":[{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:anyconnect_secure_mobility_client:4.9\\(5086\\):*:*:*:*:*:*:*","matchCriteriaId":"5E93E4C4-83B5-45E3-AF08-389494096EFA"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:o:apple:macos:-:*:*:*:*:*:*:*","matchCriteriaId":"387021A0-AF36-463C-A605-32EA7DAC172E"},{"vulnerable":false,"criteria":"cpe:2.3:o:linux:linux_kernel:-:*:*:*:*:*:*:*","matchCriteriaId":"703AF700-7A70-47E2-BC3A-7FD03B3CA9C1"},{"vulnerable":false,"criteria":"cpe:2.3:o:microsoft:windows:-:*:*:*:*:*:*:*","matchCriteriaId":"A2572D17-1DE6-457B-99CC-64AFD54487EA"}]}]}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-anyconnect-dos-55AYyxYr","source":"psirt@cisco.com","tags":["Vendor Advisory"]},{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-anyconnect-dos-55AYyxYr","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Vendor Advisory"]}]}}]}
