org/apache/catalina/realm/RealmBase.java in Apache Tomcat 6.x before 6.0.36 and 7.x before 7.0.30, when FORM authentication is used, allows remote attackers to bypass security-constraint checks by leveraging a previous setUserPrincipal call and then placing /j_security_check at the end of a URI. When using FORM authentication it was possible to bypass the security constraint checks in the FORM authenticator by appending /j_security_check to the end of the URL if some other component (such as the Single-Sign-On valve) had called request.setUserPrincipal() before the call to FormAuthenticator#authenticate().
