4.4.0.0.0, 4.4.0.2.0 and 4.4.0.3.0. Easily exploitable vulnerability
allows unauthenticated attacker with network access via HTTP to
compromise Oracle Utilities Application Framework. Successful attacks
of this vulnerability can result in unauthorized ability to cause a
hang or frequently repeatable crash (complete DOS) of Oracle
Utilities Application Framework.
Affects:
o Oracle Utilities Application Framework 4.3.0.5.0, 4.3.0.6.0,
4.4.0.0.0, 4.4.0.2.0, 4.4.0.3.0

4.5.0.0.1 and 4.5.0.1.0- 4.5.0.1.2. Easily exploitable vulnerability
allows low privileged attacker with network access via HTTP to
compromise Oracle Utilities Application Framework. Successful attacks
require human interaction from a person other than the attacker.
Successful attacks of this vulnerability can result in unauthorized
creation, deletion or modification access to critical data or all
Oracle Utilities Application Framework accessible data as well as
unauthorized read access to a subset of Oracle Utilities Application
Framework accessible data.

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]
