"CVE-2018-1258
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 3.0. Easily exploitable
vulnerability allows low privileged attacker with network access via
HTTP to compromise Oracle Health Sciences Information Manager.
Successful attacks of this vulnerability can result in takeover of
Oracle Health Sciences Information Manager.
CVE-2018-1258
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 3.0. Easily exploitable
vulnerability allows low privileged attacker with network access via
HTTP to compromise Oracle Health Sciences Information Manager.
Successful attacks of this vulnerability can result in takeover of
Oracle Health Sciences Information Manager.
CVE-2019-2430
6.5
AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
Supported versions that are affected are 8.1 and 8.2. Easily
exploitable vulnerability allows low privileged attacker with network
access via HTTP to compromise Oracle Argus Safety. Successful
attacks of this vulnerability can result in unauthorized access to
critical data or complete access to all Oracle Argus Safety
accessible data.
CVE-2019-2431
6.1
AV:N/AC:H/PR:N/UI:R/S:C/C:N/I:H/A:N
Supported versions that are affected are 8.1 and 8.2. Difficult to
exploit vulnerability allows unauthenticated attacker with network
access via HTTP to compromise Oracle Argus Safety. Successful
attacks require human interaction from a person other than the
attacker and while the vulnerability is in Oracle Argus Safety,
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 Argus
Safety accessible data.
CVE-2015-9251
6.1
AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
Supported versions that are affected are 7.1 and 7.2. Easily
exploitable vulnerability allows unauthenticated attacker with
network access via HTTP to compromise Oracle Healthcare Foundation.
Successful attacks require human interaction from a person other than
the attacker and while the vulnerability is in Oracle Healthcare
Foundation, attacks may significantly impact additional products.
Successful attacks of this vulnerability can result in unauthorized
update, insert or delete access to some of Oracle Healthcare
Foundation accessible data as well as unauthorized read access to a
subset of Oracle Healthcare Foundation accessible data.
CVE-2019-2432
4.9
AV:N/AC:H/PR:L/UI:N/S:C/C:L/I:L/A:N
Supported versions that are affected are 8.1 and 8.2. Difficult to
exploit vulnerability allows low privileged attacker with network
access via HTTP to compromise Oracle Argus Safety. While the
vulnerability is in Oracle Argus Safety, attacks may significantly
impact additional products. Successful attacks of this vulnerability
can result in unauthorized update, insert or delete access to some
of Oracle Argus Safety accessible data as well as unauthorized read
access to a subset of Oracle Argus Safety 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]
