[1]
IMPACT
The vendor has provided the following information regarding the
vulnerabilities:
"This Critical Patch Update contains 2 new security fixes for Oracle
Utilities Applications. Both of these vulnerabilities may be
remotely exploitable without authentication, i.e., may be exploited
over a network without requiring user credentials." [1]
"CVE-2016-4000
9.8
AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Supported versions that are affected are 1.12.0.3, 2.3.0.0, 2.3.0.1
and 2.3.0.2. Easily exploitable vulnerability allows unauthenticated
attacker with network access via HTTP to compromise Oracle Utilities
Network Management System. Successful attacks of this vulnerability
can result in takeover of Oracle Utilities Network Management System.
CVE-2015-9251
6.1
AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
Supported versions that are affected are 4.3.0.1-4.3.0.4. Easily
exploitable vulnerability allows unauthenticated attacker with
network access via HTTP to compromise Oracle Utilities Framework.
Successful attacks require human interaction from a person other than
the attacker and while the vulnerability is in Oracle Utilities
Framework, attacks may significantly impact additional products.
Successful attacks of this vulnerability can result in unauthorized
update, insert or delete access to some of Oracle Utilities Framework
accessible data as well as unauthorized read access to a subset of
Oracle Utilities Framework accessible data." [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]
