12.2.1.4.0. Easily exploitable vulnerability allows low privileged
attacker with network access via HTTP to compromise Oracle Business
Intelligence Enterprise Edition. Successful attacks require human
interaction from a person other than the attacker and while the
vulnerability is in Oracle Business Intelligence Enterprise Edition,
attacks may significantly impact additional products. Successful
attacks of this vulnerability can result in unauthorized update,
insert or delete access to some of Oracle Business Intelligence
Enterprise Edition accessible data as well as unauthorized read
access to a subset of Oracle Business Intelligence Enterprise Edition
accessible data.

12.2.1.4.0. Easily exploitable vulnerability allows unauthenticated
attacker with network access via HTTP to compromise Oracle HTTP
Server. Successful attacks require human interaction from a person
other than the attacker. Successful attacks of this vulnerability can
result in unauthorized update, insert or delete access to some of
Oracle HTTP Server accessible data as well as unauthorized read
access to a subset of Oracle HTTP Server accessible data.
Affects:

MITIGATION
Oracle states:
"Due to the threat posed by a successful attack, Oracle strongly
recommends that customers apply CPU fixes as soon as possible. Until
you apply the CPU fixes, it may be possible to reduce the risk of
successful attack by blocking network protocols required by an
attack. For attacks that require certain privileges or access to
certain packages, removing the privileges or the ability to access
the packages from users that do not need the privileges may help
reduce the risk of successful attack. Both approaches may break
application functionality, so Oracle strongly recommends that
customers test changes on non-production systems. Neither approach
should be considered a long-term solution as neither corrects the
underlying problem." [1]
