|
||||
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 is 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.
