CVE-2026-63079

Description

RBH Access Technologies Integra32 Security Management System 5.1.11 R5.0 contains an unauthenticated deserialization vulnerability in its deprecated .NET Remoting service, exposed on TCP port 2001 via the AxcvcLt.dll library using BinaryServerFormatterSinkProvider at TypeFilterLevel.Full without requiring authentication. A remote unauthenticated attacker can send a malicious serialized gadget payload (such as a ysoserial.net TypeConfuseDelegate chain) to the IntegraURI object endpoint, or exploit MarshalByRefObject/MarshalByValue unmarshalling for arbitrary file read/write and SMB/NTLMv2 credential coercion, to achieve remote code execution as NT AUTHORITY\SYSTEM and fully compromise the host.
