OVERVIEW
Multiple vulnerabilities have been identified in :
o Oracle Database Server, versions 11.2.0.4, 12.1.0.2,
12.2.0.1, 18c
[1]
IMPACT
The vendor has provided the following information regarding the
vulnerabilities:
"This Critical Patch Update contains 7 new security fixes for the
Oracle Database Server divided as follows:
o 3 new security fixes for the Oracle Database Server.
2 of these vulnerabilities may be remotely exploitable without
authentication, i.e., may be exploited over a network without
requiring user credentials. None of these fixes are applicable to
client-only installations, i.e., installations that do not have the
Oracle Database Server installed.
o 1 new security fix for Oracle Big Data Graph.
This vulnerability is remotely exploitable without authentication,
i.e., may be exploited over a network without requiring user
credentials.
o 3 new security fixes for Oracle GoldenGate.
All of these vulnerabilities may be remotely exploitable without
authentication, i.e., may be exploited over a network without
requiring user credentials. The English text form of this Risk
Matrix can be found here." [1]
"CVE-2018-3259
9.8
AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Easily exploitable vulnerability allows unauthenticated attacker
with network access via multiple protocols to compromise Java VM.
Successful attacks of this vulnerability can result in takeover of
Java VM.
CVE-2018-3299
8.2
AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:L/A:H
Easily exploitable vulnerability allows unauthenticated attacker
with network access via multiple protocols to compromise Oracle
Text. Successful attacks require human interaction from a person
other than the attacker and while the vulnerability is in Oracle
Text, attacks may significantly impact additional products.
Successful attacks of this vulnerability can result in unauthorized
ability to cause a hang or frequently repeatable crash (complete
DOS) of Oracle Text as well as unauthorized update, insert or delete
access to some of Oracle Text accessible data.
CVE-2018-7489
2.3
AV:A/AC:H/PR:L/UI:R/S:U/C:N/I:N/A:L
Difficult to exploit vulnerability allows low privileged attacker
having RHP User privilege with access to the physical communication
segment attached to the hardware where the Rapid Home Provisioning
executes to compromise Rapid Home Provisioning. Successful attacks
require human interaction from a person other than the attacker.
Successful attacks of this vulnerability can result in unauthorized
ability to cause a partial denial of service (partial DOS) of Rapid
Home Provisioning.
CVE-2016-6814
9.6
AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H
Supported versions that are affected are 2.0, 2.1 and 2.2. Easily
exploitable vulnerability allows unauthenticated attacker with
network access via HTTP to compromise Spatial. Successful attacks
require human interaction from a person other than the attacker and
while the vulnerability is in Spatial, attacks may significantly
impact additional products. Successful attacks of this vulnerability
can result in takeover of Spatial.
CVE-2018-2913
10.0.
AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H
Vulnerability in the Oracle GoldenGate component of Oracle
GoldenGate (subcomponent: Monitoring Manager). Supported versions
that are affected are 12.1.2.1.0, 12.2.0.2.0 and 12.3.0.1.0. Easily
exploitable vulnerability allows unauthenticated attacker with
network access via TCP to compromise Oracle GoldenGate. While the
vulnerability is in Oracle GoldenGate, attacks may significantly
impact additional products. Successful attacks of this vulnerability
can result in takeover of Oracle GoldenGate.
Note: For Linux and Windows platforms, the CVSS score is 9.0 with
Access Complexity as High. For all other platforms, the cvss score
is 10.0.
CVE-2018-2912
7.5
AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Supported versions that are affected are 12.1.2.1.0, 12.2.0.2.0 and
12.3.0.1.0. Easily exploitable vulnerability allows unauthenticated
attacker with network access via TCP to compromise Oracle
GoldenGate. Successful attacks of this vulnerability can result in
unauthorized ability to cause a hang or frequently repeatable crash
(complete DOS) of Oracle GoldenGate.
CVE-2018-2914
7.5
AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Supported versions that are affected are 12.1.2.1.0, 12.2.0.2.0 and
12.3.0.1.0. Easily exploitable vulnerability allows unauthenticated
attacker with network access via TCP to compromise Oracle
GoldenGate. Successful attacks of this vulnerability can result in
unauthorized ability to cause a hang or frequently repeatable crash
(complete DOS) of Oracle GoldenGate." [2]
MITIGATION
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]
