OVERVIEW
Multiple vulnerabilities have been identified in Oracle Sun Systems
Products Suite products:
- Solaris, versions 10, 11
- Solaris Cluster, version 4
- Sun ZFS Storage Appliance Kit (AK), version AK 2013 [1]
IMPACT
The vendor has provided the following information regarding to 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-2017-3632
9.8
AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Supported versions that are affected are 10 and 11. Easily
exploitable vulnerability allows unauthenticated attacker with
network access via TCP to compromise Solaris. Successful attacks of
this vulnerability can result in takeover of Solaris. Note:
CVE-2017-3632 is assigned to the "EASYSTREET" vulnerability.
CVE-2017-10013
8.3
AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H
The supported version that is affected is AK 2013. Difficult to
exploit vulnerability allows unauthenticated attacker with network
access via HTTP to compromise Sun ZFS Storage Appliance Kit (AK).
Successful attacks require human interaction from a person other
than the attacker and while the vulnerability is in Sun ZFS Storage
Appliance Kit (AK), attacks may significantly impact additional
products. Successful attacks of this vulnerability can result in
takeover of Sun ZFS Storage Appliance Kit (AK).
CVE-2017-10042
7.5
AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Supported versions that are affected are 10 and 11. Easily
exploitable vulnerability allows unauthenticated attacker with
network access via IKE to compromise Solaris. Successful attacks of
this vulnerability can result in unauthorized ability to cause a
hang or frequently repeatable crash (complete DOS) of Solaris.
CVE-2017-10036
7.5
AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Supported versions that are affected are 10 and 11. Easily
exploitable vulnerability allows unauthenticated attacker with
network access via NFSv4 to compromise Solaris. Successful attacks
of this vulnerability can result in unauthorized ability to cause a
hang or frequently repeatable crash (complete DOS) of Solaris.
CVE-2017-10016
7.5
AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H
The supported version that is affected is AK 2013. Difficult to
exploit vulnerability allows unauthenticated attacker with network
access via HTTP to compromise Sun ZFS Storage Appliance Kit (AK).
Successful attacks require human interaction from a person other
than the attacker. Successful attacks of this vulnerability can
result in takeover of Sun ZFS Storage Appliance Kit (AK).
CVE-2017-10234
7.3
AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H
The supported version that is affected is 4. Easily exploitable
vulnerability allows low privileged attacker with logon to the
infrastructure where Solaris Cluster executes to compromise Solaris
Cluster. Successful attacks require human interaction from a person
other than the attacker. Successful attacks of this vulnerability
can result in takeover of Solaris Cluster.
CVE-2017-10004
6.7
AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H
Supported versions that are affected are 10 and 11. Easily
exploitable vulnerability allows high privileged attacker with logon
to the infrastructure where Solaris executes to compromise Solaris.
Successful attacks of this vulnerability can result in takeover of
Solaris.
CVE-2017-10062
5.3
AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L
The supported version that is affected is 10. Easily exploitable
vulnerability allows low privileged attacker with logon to the
infrastructure where Solaris executes to compromise Solaris.
Successful attacks of this vulnerability can result in unauthorized
update, insert or delete access to some of Solaris accessible data
as well as unauthorized read access to a subset of Solaris
accessible data and unauthorized ability to cause a partial denial
of service (partial DOS) of Solaris.
CVE-2017-10003
4.5
AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:L
The supported version that is affected is 10. Difficult to exploit
vulnerability allows low privileged attacker with logon to the
infrastructure where Solaris executes to compromise Solaris.
Successful attacks of this vulnerability can result in unauthorized
update, insert or delete access to some of Solaris accessible data
as well as unauthorized read access to a subset of Solaris
accessible data and unauthorized ability to cause a partial denial
of service (partial DOS) of Solaris.

3.3
AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N
The supported version that is affected is 11. Easily exploitable
vulnerability allows unauthenticated attacker with logon to the
infrastructure where Solaris executes to compromise Solaris.
Successful attacks require human interaction from a person other
than the attacker. Successful attacks of this vulnerability can
result in unauthorized update, insert or delete access to some of
Solaris accessible data.
CVE-2017-10122
1.8

Supported versions that are affected are 10 and 11. Difficult to
exploit vulnerability allows high privileged attacker with logon to
the infrastructure where Solaris executes to compromise Solaris.
Successful attacks require human interaction from a person other
than the attacker. Successful attacks of this vulnerability can
result in unauthorized update, insert or delete access to some of
Solaris 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]
