'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.
