Improper Input Validation
Multiple open redirect vulnerabilities in TBDev.NET 01-01-08 allow remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via (1) the returnto parameter to login.php or (2) the returnto parameter in a delete action to news.php. NOTE: this can be leveraged for cross-site scripting (XSS) by redirecting to a data: URI.
CWE-20 - Improper Input Validation
