The vulnerability is due to insufficient controls for specific memory operations. An attacker could exploit this vulnerability by sending a malformed Extensible Messaging and Presence Protocol (XMPP) authentication request to an affected system. A successful exploit could allow the attacker to cause an unexpected restart of the authentication service, preventing users from successfully authenticating. Exploitation of this vulnerability does not impact users who were authenticated prior to an attack."},{"lang":"es","value":"Una vulnerabilidad en el servicio de identificación de Cisco Unified Communications Manager IM and Presence (Unified CM IM&P) Service, Cisco TelePresence Video Communication Server (VCS), and Cisco Expressway Series, podría permitir a un atacante remoto no identificado causar una interrupción del servicio para usuarios que intentan autenticarse, lo que resulta en una condición de Denegación de Servicio (DoS). La vulnerabilidad es debido a controles insuficientes para operaciones de memoria específicas. Un atacante podría explotar esta vulnerabilidad mediante el envió de una petición de autorización malformada de tipo Extensible Messaging and Presence Protocol (XMPP) hacia un sistema afectado. Una operación con éxito podría permitir al atacante causar un reinicio inesperado del servicio de autenticación, que evitaría que los usuarios identificarse correctamente. La explotación de esta vulnerabilidad no afecta a los usuarios que se autenticaron anterior a un ataque."}],"metrics":{"cvssMetricV30":[{"source":"psirt@cisco.com","type":"Secondary","cvssData":{"version":"3.0","vectorString":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","baseScore":8.6,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":4.0},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.0","vectorString":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","baseScore":8.6,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":4.0}],"cvssMetricV2":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"2.0","vectorString":"AV:N/AC:L/Au:N/C:N/I:N/A:P","baseScore":5.0,"accessVector":"NETWORK","accessComplexity":"LOW","authentication":"NONE","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"PARTIAL"},"baseSeverity":"MEDIUM","exploitabilityScore":10.0,"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-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:telepresence_video_communication_server:*:*:*:*:*:*:*:*","versionStartIncluding":"x8.1","versionEndIncluding":"x12.5.2","matchCriteriaId":"8B69A77D-61EA-4BEC-ACF8-B8768CFAFB43"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:unified_communications_manager_im_and_presence_service:11.5\\(1\\):*:*:*:*:*:*:*","matchCriteriaId":"34D89C42-AAD9-4B04-9F95-F77681E39553"}]}]}],"references":[{"url":"http://www.securityfocus.com/bid/108615","source":"psirt@cisco.com","tags":["Third Party Advisory","VDB Entry"]},{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190605-cucm-imp-dos","source":"psirt@cisco.com","tags":["Vendor Advisory"]},{"url":"http://www.securityfocus.com/bid/108615","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Third Party Advisory","VDB Entry"]},{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190605-cucm-imp-dos","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Vendor Advisory"]}]}}]}
