Official Description
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."
Technical Analysis
CVE-2008-3466 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
From a weakness classification perspective (CWE-287): Authentication bypass vulnerabilities allow attackers to access protected resources without valid credentials.
