Improper certificate validation could allow an attacker in a privileged network position to read data from and write data to the encrypted communication channel between the app and a server. The security vulnerability could be exploited by an attacker in a privileged network position which allows intercepting the communication channel between the affected app and a server (such as Man-in-the-Middle). Furthermore, an attacker must be able to generate a certificate that results for the validation algorithm in a checksum identical to a trusted certificate. Successful exploitation requires no user interaction. The vulnerability could allow reading data from and writing data to the encrypted communication channel between the app and a server, impacting the communication's confidentiality and integrity. At the time of advisory publication no public exploitation of this security vulnerability was known. Siemens confirms the security vulnerability and provides mitigations to resolve the security issue."},{"lang":"es","value":"Se ha identificado una vulnerabilidad en Siveillance VMS Video for Android (todas las versiones anteriores a la V12.1a (2018 R1)) y Siveillance VMS Video for iOS (todas las versiones anteriores a la V12.1a (2018 R1)). La validación incorrecta de certificados podría permitir que un atacante en una posición de red privilegiada lea y escriba datos en el canal de comunicaciones cifrado entre la aplicación y un servidor. La vulnerabilidad de seguridad podría ser explotada por un atacante en una posición de red privilegiada, lo que permite que el canal de comunicación entre la aplicación afectada y un servidor se pueda interceptar (como un Man-in-the-Middle). Además, un atacante debe ser capaz de generar un certificado que resulte del algoritmo de validación en una suma de verificación idéntica a la del certificado de confianza. La explotación con éxito no requiere de interacción con el usuario. La vulnerabilidad podría permitir que se lean y escriban datos en el canal de comunicación cifrado entre la aplicación y un servidor, lo que impacta la confidencialidad e integridad de las comunicaciones. En el momento de la publicación del advisory, no se conoce ninguna explotación pública de la vulnerabilidad de seguridad.
