					This module exploits a stack buffer overflow in the MaxDB WebDBM
				service. This service is included with many recent versions
				of the MaxDB and SAPDB products. This particular module is
				capable of exploiting Windows systems through the use of an
				SEH frame overwrite. The offset to the SEH frame may change
				depending on where MaxDB has been installed, this module
				assumes a web root path with the same length as:
