# Information About Software :

# Impact :  
***********  
WordPress 4.x.x/5.x.x AND-AntiBounce Plugins 1.0.3 and other versions 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.
