A remote code execution vulnerability exists in the SNA Remote Procedure Call (RPC) service for Host Integration Server. An attacker could exploit the vulnerability by constructing a specially crafted RPC request. The vulnerability could allow remote code execution. An attacker who successfully exploited this vulnerability could take complete control of an affected system.

To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2008-3466.

Mitigating Factors for HIS Command Execution Vulnerability - CVE- 2008-3466

Mitigation refers to a setting, common configuration, or general best-practice, existing in a default state, that could reduce the severity of exploitation of a vulnerability. The following mitigating factors may be helpful in your situation:

  • An attacker who successfully exploited this vulnerability could gain the same user rights as the SNA service account as specified during the install of Host Integration Server. Customers who follow best practices and configure the SNA RPC service account to have fewer user rights on the system could be less impacted than customers who configure the SNA service account to have administrative user rights.
  • For systems with Microsoft Host Integration Server 2000 Administrator Client or the Microsoft Host Integration Server 2004 Client, the default installation does not create or start the SNA Remote Procedure Call (RPC) service where the vulnerability exists. However; the files are installed by default and can be started therefore we highly recommend that customers apply the update if they have a vulnerable version of the product.

Workarounds for HIS Command Execution Vulnerability - CVE- 2008-3466

Workaround refers to a setting or configuration change that does not correct the underlying vulnerability but would help block known attack vectors before you apply the update. Microsoft has tested the following workarounds and states in the discussion whether a workaround reduces functionality:

  • For Host Integration Server 2004 and Host Integration Server 2006, do not configure the HIS/SNA service to run with an Administrator Account.
    • When first installing Host Integration Server, administrators are prompted for an account to run the SNA RPC service with. Customers should follow best practices and select an account with non-administrative privileges.
    • The SNA service can be configured to use a lower privileged account through the Configuration Tool under the Host Integration Server folder in the Start menu.

    Note This workaround is not available for Host Integration Server 2000.

    Impact of workaround. None. Following best practices, the SNA service should be run with an account with non-administrative privileges.

  • For Host Integration Server 2000, Host Integration Server 2004 and Host Integration Server 2006, disable the SNA RPC Service.
    1. To disable the affected service change the SnaRpcService service to disabled. This service is used to add performance counters and refresh the bindings when adding link services or additional SNA Server services to a server.
    2. Once these configuration tasks are completed, disable the SNA RPC service.

    Impact of workaround. Normal runtime operation and additional configuration changes, such as adding connections, are not dependent on the SNA RPC service. However, if link services or nodes are added while this service is disabled, the associated performance counters will not be added and the SNA MngAgent service will need to be recycled for the configuration changes to be reflected in the SNA Manager. The collection of performance data is not impacted when the SNA RPC service is disabled.

FAQ for HIS Command Execution Vulnerability - CVE- 2008-3466

What is the scope of the vulnerability? 
This is a remote code execution vulnerability. An attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

What causes the vulnerability? 
Specially crafted RPC requests allow remote unauthenticated users to bypass authentication within the SNA RPC service.

What is RPC? 
Remote Procedure Call (RPC) is a protocol that a program can use to request a service from a program located on another computer in a network. RPC helps with interoperability because the program using RPC does not have to understand the network protocols that are supporting communication. In RPC, the requesting program is the client and the service-providing program is the server.

What might an attacker use the vulnerability to do? 
An attacker who successfully exploited this vulnerability could take complete control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

How could an attacker exploit the vulnerability? 
An attacker could try to exploit the vulnerability by creating a specially crafted RPC message and sending the message to an affected system over the RPC TCP/UDP port which is dynamically assigned by Host Integration Server.

What systems are primarily at risk from the vulnerability? 
All systems that have the affected Microsoft Host Integration Server installed are at risk from this vulnerability.

What does the update do? 
This update removes the vulnerability by restricting access to the administrative functions exposed by RPC.

When this security bulletin was issued, had this vulnerability been publicly disclosed? 
No. Microsoft received information about this vulnerability through responsible disclosure. Microsoft had not received any information to indicate that this vulnerability had been publicly disclosed when this security bulletin was originally issued.

When this security bulletin was issued, had Microsoft received any reports that this vulnerability was being exploited? 
No. Microsoft had not received any information to indicate that this vulnerability had been publicly used to attack customers and had not seen any examples of proof of concept code published when this security bulletin was originally issued.
