What is CVE-2020-8143?

An Open Redirect vulnerability exists in Revive Adserver versions prior to 5.0.5, allowing remote attackers to redirect users to malicious sites. If a user is tricked into clicking a specially crafted link, they may be redirected to an unintended destination. This issue arises due to the potential bypass of CSRF protection on the '/www/admin/*-modify.php' endpoint, especially when no meaningful parameters are provided. Although no action is taken, users experience redirection dictated by the 'returnurl' GET parameter, compromising their browsing security.
