CVE-2026-23746: Entrust Instant Financial Issuance (IFI) SmartCardController Service .NET Remoting RCE

• Severity: critical (CVSS 9.3 v4.0)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 1.2% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-01-15 · updated 2026-06-17
• Weakness: CWE-306

Description

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. 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.
