MSS: (PerformRouterDiscovery) Allow IRDP to detect and configure Default Gateway addresses (could lead to DoS)
Counter Measure:
Configure the MSS: (PerformRouterDiscovery) Allow IRDP to detect and configure Default Gateway addresses (could lead to DoS) entry to a value of Disabled.
The possible values for this registry entry are:
? 0, 1, or 2. The default configuration is 2 (enable only if DHCP sends the Perform Router Discovery option).
In the SCE UI, these options appear as:
? 0 (Disabled)
? 1 (Enabled)
? 2 (enable only if DHCP sends the Perform Router Discovery option)
? Not Defined
Potential Impact:
If you disable this entry, Windows Server 2003 (which supports the IRDP) cannot automatically detect and configure default gateway addresses on the computer.
Fix:
(1) GPO: Computer Configuration\Administrative Templates\MSS (Legacy)\MSS: (PerformRouterDiscovery) Allow IRDP to detect and configure Default Gateway addresses (could lead to DoS)
(2) REG: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters!PerformRouterDiscovery
