DESCRIPTION:
A vulnerability has been reported in Oracle Mojarra, which can be
exploited by malicious people to bypass certain security
restrictions.

The vulnerability is caused due to an error when parsing parameters
in a Java Bean, which can lead to certain parameters being evaluated
as an EL (expression language) expression.

Successful exploitation requires that "includeViewParameters" is set
to "true" in the Java Bean.

SOLUTION:
Apply patch.
