IMPACT
The vendor has provided the following information regarding the
vulnerabilities:
"This Critical Patch Update contains 11 new security fixes for the
Oracle Sun Systems Products Suite. 5 of these vulnerabilities may
be remotely exploitable without authentication, i.e., may be
exploited over a network without requiring user credentials." [1]
"CVE-2017-5645
9.8
AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
The supported version that is affected is 8.4. Easily exploitable
vulnerability allows unauthenticated attacker with network access via
HTTP to compromise Tape Library ACSLS. Successful attacks of this
vulnerability can result in takeover of Tape Library ACSLS.
CVE-2018-1275
9.8
AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
The supported version that is affected is 8.4. Easily exploitable
vulnerability allows unauthenticated attacker with network access via
HTTP to compromise Tape Library ACSLS. Successful attacks of this
vulnerability can result in takeover of Tape Library ACSLS.
CVE-2016-0635
8.8
AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
The supported version that is affected is 8.4. Easily exploitable
vulnerability allows low privileged attacker with network access via
HTTP to compromise Tape Library ACSLS. Successful attacks of this
vulnerability can result in takeover of Tape Library ACSLS.
CVE-2019-2541
7.5
AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
The supported version that is affected is 10. Difficult to exploit
vulnerability allows unauthenticated attacker with access to the
physical communication segment attached to the hardware where the
Oracle Solaris executes to compromise Oracle Solaris. Successful
attacks of this vulnerability can result in takeover of Oracle
Solaris.
CVE-2019-2437
7.5
AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
The supported version that is affected is 11. Easily exploitable
vulnerability allows unauthenticated attacker with network access via
TCP to compromise Oracle Solaris. Successful attacks of this
vulnerability can result in unauthorized ability to cause a hang or
frequently repeatable crash (complete DOS) of Oracle Solaris.
CVE-2019-2412
6.4
AV:L/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H
The supported version that is affected is prior to 8.8.2. Difficult
to exploit vulnerability allows high privileged attacker with logon
to the infrastructure where Sun ZFS Storage Appliance Kit (AK)
executes to compromise Sun ZFS Storage Appliance Kit (AK).
Successful attacks of this vulnerability can result in takeover of
Sun ZFS Storage Appliance Kit (AK).
CVE-2018-3646
5.6
AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:N/A:N
The supported version that is affected is 11. Difficult to exploit
vulnerability allows low privileged attacker with logon to the
infrastructure where Oracle Solaris executes to compromise Oracle
Solaris. While the vulnerability is in Oracle Solaris, attacks may
significantly impact additional products. Successful attacks of this
vulnerability can result in unauthorized access to critical data or
complete access to all Oracle Solaris accessible data.
CVE-2018-3639
5.5
AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
The supported version that is affected is 11. Easily exploitable
vulnerability allows low privileged attacker with logon to the
infrastructure where Oracle Solaris executes to compromise Oracle
Solaris. Successful attacks of this vulnerability can result in
unauthorized access to critical data or complete access to all Oracle
Solaris accessible data.
CVE-2019-2543
5.3
AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
Supported versions that are affected are 10 and 11. Easily
exploitable vulnerability allows unauthenticated attacker with
network access via KSSL to compromise Oracle Solaris. Successful
attacks of this vulnerability can result in unauthorized read access
to a subset of Oracle Solaris accessible data.
CVE-2019-2544
4.0

4.0
AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L
Supported versions that are affected are 10 and 11. Easily
exploitable vulnerability allows unauthenticated attacker with logon
to the infrastructure where Oracle Solaris executes to compromise
Oracle Solaris. Successful attacks of this vulnerability can result
in unauthorized ability to cause a partial denial of service (partial
DOS) of Oracle Solaris." [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]
