Descriptions

A vulnerability in the certificate management subsystem of Cisco AnyConnect Network Access Manager and of Cisco AnyConnect Secure Mobility Client for iOS, Mac OS X, Android, Windows, and Linux could allow an unauthenticated, remote attacker to bypass the TLS certificate check when downloading certain configuration files. The vulnerability is due to improper use of Simple Certificate Enrollment Protocol and improper server certificate validation. An attacker could exploit this vulnerability by preparing malicious profile and localization files for Cisco AnyConnect to use. A successful exploit could allow the attacker to remotely change the configuration profile, a certificate, or the localization data used by AnyConnect Secure Mobility Client. Cisco Bug IDs: CSCvh23141.

Una vulnerabilidad en el subsistema de gestión de certificados de Cisco AnyConnect Network Access Manager y Cisco AnyConnect Secure Mobility Client para iOS, Mac OS X, Android, Windows y Linux podría permitir que un atacante remoto no autenticado omita la comprobación de certificados TLS al descargar ciertos archivos de configuración. La vulnerabilidad se deba al uso incorrecto del protocolo Simple Certificate Enrollment y a una validación incorrecta del certificado del servidor. Un atacante podría explotar esta vulnerabilidad preparando archivos maliciosos del perfil y localización para que sean empleados por Cisco AnyConnect. Su explotación con éxito podría permitir que el atacante cambie remotamente el perfil de configuración, un certificado o los datos de localización empleados por AnyConnect Secure Mobility Client. Cisco Bug IDs: CSCvh23141.
