What is Open Redirect vulnerability?

Open redirect vulnerabilities allow the attacker to use a well known website name to redirect the visitor to another website.

As mentioned in Everything is vulnerable ( Q4 in internet wars ). You should pay attention to URLs you visit by inspecting the form of the address carefully to make sure the address represents the website you are visiting.

However, Open redirect vulnerability is a development fault, As it allows the attacker to easily use the system to redirect users to another website without giving the user any clues about being redirected.
