Description

This module exploits a lack of authentication and access control in HP Intelligent Management, specifically in the AccountService RpcServiceServlet from the SOM component, in order to create a SOM account with Account Management permissions. This module has been tested successfully on HP Intelligent Management Center 5.2 E0401 and 5.1 E202 with SOM 5.2 E0401 and SOM 5.1 E0201 over Windows 2003 SP2.
