'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).
