CVE-2026-23746

Estado: AplazadaCrítica (9.3)—

Entrust Instant Financial Issuance (IFI) On Premise software (formerly referred to as CardWizard) versions 5.x, prior to 6.10.5, and prior to 6.11.1 contain an insecure .NET Remoting exposure in the SmartCardController service (DCG.SmartCardControllerService.exe). The service registers a TCP remoting channel with unsafe formatter/settings that permit untrusted remoting object invocation.

Leer descripción completaMostrar menos

A remote, unauthenticated attacker who can reach the remoting port can invoke exposed remoting objects to read arbitrary files from the server and coerce outbound authentication, and may achieve arbitrary file write and remote code execution via known .NET Remoting exploitation techniques. This can lead to disclosure of sensitive installation and service-account data and compromise of the affected host.

Esto puede llevar a la divulgación de datos sensibles de instalación y de cuentas de servicio y al compromiso del host afectado."
