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. Whether this issue poses a vulnerability will be subject to the intended behavior of the application. For example, a search engine might intentionally provide redirects to arbitrary URLs.","Draft","Base","Simple",false,[],{"title":86,"metaDescription":87,"keywords":88,"canonicalUrl":89,"structuredData":90},"What is CVE-2017-11879?
