Question

Why might an attacker use the parameter pollution technique with two different values for the same input variable?

a.

b.

To bypass content filtering mechanisms

c.

To improve input validation controls

d.

To trigger a web application firewall

Answer: (b).To bypass content filtering mechanisms Explanation:Attackers use parameter pollution with two different values to obscure the injection attack and bypass content filtering mechanisms.
