|

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 code 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.
