Microsoft Host Integration Server (HIS) 2000, 2004, and 2006 does not limit RPC access to administrative functions, which allows remote attackers to bypass authentication and execute arbitrary programs via a crafted SNA RPC message using opcode 1 or 6 to call the CreateProcess function, aka "HIS Command Execution Vulnerability."
