Apache Tomcat is a servlet container.
It was found that when an application used FORM authentication, along
with another component that calls request.setUserPrincipal() before
the call to FormAuthenticator#authenticate() (such as the
Single-Sign-On valve), it was possible to bypass the security
constraint checks in the FORM authenticator by appending
'/j_security_check' to the end of a URL. A remote attacker with an
authenticated session on an affected application could use this flaw
to circumvent authorization controls, and thereby access resources not
permitted by the roles associated with their authenticated session.
