SAP Biller Direct allows an unauthenticated attacker to craft a legitimate looking URL. When clicked by an unsuspecting victim, it will use an unsensitized parameter to redirect the victim to a malicious site of the attacker's choosing which can result in disclosure or modification of the victim's information.
The web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a redirect.
