IMPACT
The vendor has provided the following information regarding the
vulnerabilities:
"This Critical Patch Update contains 6 new security patches for
Oracle Health Sciences Applications. 3 of these vulnerabilities may
be remotely exploitable without authentication, i.e., may be
exploited over a network without requiring user credentials." [1]
CVE-2019-17195
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 8.1.0. Easily exploitable
vulnerability allows unauthenticated attacker with network access via
HTTP to compromise Oracle Healthcare Data Repository. Successful
attacks of this vulnerability can result in takeover of Oracle
Healthcare Data Repository.
Affects:
o Oracle Healthcare Data Repository 8.1.0
CVE-2021-22118
7.8 AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
The supported version that is affected is 8.1.0. Easily exploitable
vulnerability allows low privileged attacker with logon to the
infrastructure where Oracle Healthcare Data Repository executes to
compromise Oracle Healthcare Data Repository. Successful attacks of
this vulnerability can result in takeover of Oracle Healthcare Data
Repository.
Affects:
o Oracle Healthcare Data Repository 8.1.0
CVE-2020-11022
6.1 AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
Supported versions that are affected are 6.2.0 and 6.3.0. Easily
exploitable vulnerability allows unauthenticated attacker with
network access via HTTP to compromise Oracle Health Sciences Central
Coding. Successful attacks require human interaction from a person
other than the attacker and while the vulnerability is in Oracle
Health Sciences Central Coding, attacks may significantly impact
additional products. Successful attacks of this vulnerability can
result in unauthorized update, insert or delete access to some of
Oracle Health Sciences Central Coding accessible data as well as
unauthorized read access to a subset of Oracle Health Sciences
Central Coding accessible data.
Affects:
o Oracle Health Sciences Central Coding 6.2.0, 6.3.0
CVE-2020-11023
6.1 AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
The supported version that is affected is 6.3.0. Easily exploitable
vulnerability allows unauthenticated attacker with network access via
HTTP to compromise Oracle Health Sciences InForm. Successful attacks
require human interaction from a person other than the attacker and
while the vulnerability is in Oracle Health Sciences InForm, attacks
may significantly impact additional products. Successful attacks of
this vulnerability can result in unauthorized update, insert or
delete access to some of Oracle Health Sciences InForm accessible
data as well as unauthorized read access to a subset of Oracle Health
Sciences InForm accessible data.
Affects:
o Oracle Health Sciences InForm 6.3.0
CVE-2020-17521
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 7.0.2. Easily exploitable
vulnerability allows low privileged attacker with logon to the
infrastructure where Oracle Healthcare Data Repository executes to
compromise Oracle Healthcare Data Repository. Successful attacks of
this vulnerability can result in unauthorized access to critical data
or complete access to all Oracle Healthcare Data Repository
accessible data.
Affects:
o Oracle Healthcare Data Repository 7.0.2
CVE-2021-28657
5.5 AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H
Supported versions that are affected are 7.3, 8.0 and 8.1. Easily
exploitable vulnerability allows unauthenticated attacker with logon
to the infrastructure where Oracle Healthcare Foundation executes to
compromise Oracle Healthcare Foundation. 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 hang or frequently repeatable crash (complete DOS) of Oracle
Healthcare Foundation.
Affects:
o Oracle Healthcare Foundation 7.3, 8.0, 8.1
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]
