8.1.3.0, 8.1.3.2 and 8.1.3.4. Easily exploitable vulnerability
allows
low privileged attacker with logon to the infrastructure where
Oracle
Healthcare Data Repository executes to compromise Oracle Healthcare
Data Repository. Successful attacks of this vulnerability can
result
in unauthorized creation, deletion or modification access to
critical
data or all Oracle Healthcare Data Repository accessible data as
well
as unauthorized access to critical data or complete access to all
Oracle Healthcare Data Repository accessible data.
Affects:

8.1.3.0, 8.1.3.2 and 8.1.3.4. Easily exploitable vulnerability
allows
low privileged attacker with network access via HTTP to compromise
Oracle Healthcare Data Repository. Successful attacks of this
vulnerability can result in unauthorized ability to cause a hang or
frequently repeatable crash (complete DOS) of Oracle Healthcare
Data
Repository.
Affects:
o Oracle Healthcare Data Repository 8.1.0.0, 8.1.1.0, 8.1.2.0,
8.1.3.0, 8.1.3.2, 8.1.3.4" [2]
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]
