Description: Open redirection is a web application vulnerability that allows an attacker to redirect users to a malicious site. This technique relies on manipulating redirection parameters in an application, where an attacker can modify the destination URL to lead the victim to an unauthorized site. Open redirection occurs when a web application trusts user input to determine the address to which it redirects, without adequately validating that the destination URL is safe. This can result in phishing attacks, where users are tricked into entering sensitive information on a fake site that mimics a legitimate one. The vulnerability is particularly dangerous because it can be difficult for users to detect, as they may not realize they have been redirected to a malicious site. Open redirection is a common issue in web applications that use URL parameters for navigation, and its exploitation can have serious consequences for both users and the reputation of the affected organization.
