"The version of Oracle WebCenter Content running on the remote host is affected by a vulnerability in the Oracle
WebCenter Content component of Oracle Fusion Middleware (subcomponent: Content Server). Supported versions that are
affected are 11.1.1.9.0, 12.2.1.2.0 and 12.2.1.3.0. An easy to exploit vulnerability allows a low privileged attacker
with network access via HTTP to compromise Oracle WebCenter Content. A successful attack requires human interaction from
a person other than the attacker and while the vulnerability is in Oracle WebCenter Content, attacks may significantly
impact additional products. Successful attacks of this vulnerability can result in unauthorized access to critical data
or complete access to all Oracle WebCenter Content accessible data as well as unauthorized update, insert or delete
access to some of Oracle WebCenter Content accessible data and unauthorized ability to cause a partial denial of service
(partial DOS) of Oracle WebCenter Content.");
