# Impact :
*********
This web application vBulletin vBulletin 4.2.5 Ajax Threads 1.1.3 Lite accepts a user-controlled

input that specifies a link to an external site, and uses that link in a Redirect.

This simplifies phishing attacks. An http parameter may contain a URL value and could cause

the web application to redirect the request to the specified URL. By modifying the URL value

to a malicious site, an attacker may successfully launch a phishing scam and steal user credentials.

Because the server name in the modified link is identical to the original site, phishing attempts

have a more trustworthy appearance.

Open redirect is a failure in that process that makes it possible for attackers to

steer users to malicious websites. This vulnerability is used in phishing attacks to get users

to visit malicious sites without realizing it. Web users often encounter redirection when they

 visit the Web site of a company whose name has been changed or which has been acquired

by another company. Visiting unreal web page user's computer becomes affected by malware

the task of which is to deceive the valid actor and steal his personal data.
