-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Oracle GlassFish Application Server and
Oracle Java Application Server. Authentication is not required to
exploit this vulnerability. 

The flaw exists within the Web Administration component which listens by
default on TCP port 4848. When handling a malformed GET request to the
administrative interface, the application does not properly handle an
exception allowing the request to proceed without authentication. A
remote attacker can exploit this vulnerability to execute arbitrary code
under the context of the application.

-- Vendor Response:
Oracle has issued an update to correct this vulnerability. More
