An issue was discovered in DTEX DEC-M (DTEX Forwarder) 6.1.1. The com.dtexsystems.helper service, responsible for handling privileged operations within the macOS DTEX Event Forwarder agent, fails to implement critical client validation during XPC interprocess communication (IPC). Specifically, the service does not verify the code requirements, entitlements, security flags, or version of any client attempting to establish a connection. This lack of proper logic validation allows malicious actors to exploit the service's methods via unauthorized client connections, and escalate privileges to root by abusing the DTConnectionHelperProtocol protocol's submitQuery method over an unauthorized XPC connection.
A particular privilege, role, capability, or right can be used to perform unsafe actions that were not intended, even when it is assigned to the correct entity.
