Compass Security discovered a web application security flaw in the OpenAM application which allows an attacker to launch phishing attacks against users by redirecting them to a malicious website. An attacker is able to create a link that, when visited, will redirect the user to a website of the attacker's choosing once the victim attempts to login. This allows, for instance, phishing of user credentials. Since it is the victim who needs to visit the malicious link, this attack is possible for unauthenticated attackers who do not have access to the affected websites. Versions 9.5.5, 10.0.2, 10.1.0-Xpress, 11.0.0 through 11.0.3, and 12.0.0 through 12.0.2 are vulnerable.
