IMPACT
The vendor has provided the following information regarding the
vulnerabilities:
"This Critical Patch Update contains 8 new security patches for
Oracle Communications Applications. 6 of these vulnerabilities may be
remotely exploitable without authentication, i.e., may be exploited
over a network without requiring user credentials." [1]
CVE-2020-14195
8.1 AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
The supported version that is affected is 8.0.0.4.0. Difficult to
exploit vulnerability allows unauthenticated attacker with network
access via HTTP to compromise Oracle Communications Calendar Server.
Successful attacks of this vulnerability can result in takeover of
Oracle Communications Calendar Server.
Affects:
o Oracle Communications Calendar Server 8.0.0.4.0
o Oracle Communications Contacts Server 8.0.0.5.0
CVE-2019-17566
7.5 AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N
Supported versions that are affected are 6.3.0-6.3.1. Easily
exploitable vulnerability allows unauthenticated attacker with
network access via HTTP to compromise Oracle Communications MetaSolv
Solution. Successful attacks of this vulnerability can result in
unauthorized creation, deletion or modification access to critical
data or all Oracle Communications MetaSolv Solution accessible data.
Affects:
o Oracle Communications MetaSolv Solution 6.3.0-6.3.1
CVE-2020-13871
7.5 AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Supported versions that are affected are 6.0.1 and 12.0.2. Easily
exploitable vulnerability allows unauthenticated attacker with
network access via SQL to compromise Oracle Communications Network
Charging and Control. Successful attacks of this vulnerability can
result in unauthorized ability to cause a hang or frequently
repeatable crash (complete DOS) of Oracle Communications Network
Charging and Control.
Affects:
o Oracle Communications Network Charging and Control 6.0.1,
12.0.2
CVE-2019-10086
7.3 AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L
Supported versions that are affected are 11.3.0.9 and 12.0.0.3.
Easily exploitable vulnerability allows unauthenticated attacker with
network access via TCP/IP to compromise Oracle Communications BRM -
Elastic Charging Engine. Successful attacks of this vulnerability can
result in unauthorized update, insert or delete access to some of
Oracle Communications BRM - Elastic Charging Engine accessible data
as well as unauthorized read access to a subset of Oracle
Communications BRM - Elastic Charging Engine accessible data and
unauthorized ability to cause a partial denial of service (partial
DOS) of Oracle Communications BRM - Elastic Charging Engine.
Affects:
o Oracle Communications BRM - Elastic Charging Engine 11.3.0.9,
12.0.0.3
o Oracle Communications MetaSolv Solution 6.3.0-6.3.1
CVE-2020-5421
6.5 AV:N/AC:H/PR:L/UI:R/S:C/C:L/I:H/A:N
Supported versions that are affected are 11.3.0.9 and 12.0.0.3.
Difficult to exploit vulnerability allows low privileged attacker
with network access via TCP/IP to compromise Oracle Communications
BRM - Elastic Charging Engine. Successful attacks require human
interaction from a person other than the attacker and while the
vulnerability is in Oracle Communications BRM - Elastic Charging
Engine, attacks may significantly impact additional products.
Successful attacks of this vulnerability can result in unauthorized
creation, deletion or modification access to critical data or all
Oracle Communications BRM - Elastic Charging Engine accessible data
as well as unauthorized read access to a subset of Oracle
Communications BRM - Elastic Charging Engine accessible data.
Affects:
o Oracle Communications BRM - Elastic Charging Engine 11.3.0.9,
12.0.0.3
CVE-2020-1945
6.2 AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
The supported version that is affected is 7.3. Easily exploitable
vulnerability allows unauthenticated attacker with logon to the
infrastructure where Oracle Communications ASAP executes to
compromise Oracle Communications ASAP. Successful attacks of this
vulnerability can result in unauthorized access to critical data or
complete access to all Oracle Communications ASAP accessible data.
Affects:
o Oracle Communications ASAP 7.3
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]
