Vijay,

The risk will be determined by the threat, and value of the associated
asset (web server and its content) coupled with its vulnerability. Risk
= Threat x Vulnerability (likelihood of threat's success) x Cost(Value
to replace). The vulnerability is only one part and only you know the
other 2 aspects.

You need to answer some questions like:

Is the web server in a DMZ, Honeypot, secured portion of the network?
These items help determine the threat level.

Vulnerability is heavily determined by degree of exposure and its
frequency (Is this always the case?)

Cost is influenced by impact. If the web server is compromised will
business shut down or simply inconvenience everyone. How sensitive is
the data (salaries, trade secrets, or simply inventory.

My suggestion is to gather all these elements to compute the risk and of
course test to validate your findings.
