# Impact :
***********
Koha Library Software 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.
