IMPACT
The vendor has provided the following information regarding the
vulnerabilities:
"This Critical Patch Update contains 8 new security fixes for Oracle
PeopleSoft Products. 5 of these vulnerabilities may be remotely
exploitable without authentication, i.e., may be exploited over a
network without requiring user credentials." [1]
CVE-2015-0226
7.5 AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
Easily exploitable vulnerability allows unauthenticated attacker with
network access via HTTP to compromise the affected system. Successful
attacks of this vulnerability can result in unauthorized access to
critical data or complete access to all the affected system's
accessible data.
Affects:
o PeopleSoft Enterprise PeopleTools 8.55, 8.56, 8.57
CVE-2019-2748
7.1 AV:N/AC:H/PR:L/UI:N/S:C/C:L/I:H/A:N
Difficult to exploit vulnerability allows low privileged attacker
with network access via HTTP to compromise the affected system. While
the vulnerability is in the affected system, 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 the affected system's
accessible data as well as unauthorized read access to a subset of
the affected system's accessible data.
Affects:
o PeopleSoft Enterprise PT PeopleTools 8.55, 8.56, 8.57
CVE-2019-2599
6.5 AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
Easily exploitable vulnerability allows low privileged attacker with
network access via HTTP to compromise the affected system. Successful
attacks of this vulnerability can result in unauthorized access to
critical data or complete access to all the affected system's
accessible data.
Affects:
o PeopleSoft Enterprise PT PeopleTools 8.55, 8.56, 8.57
CVE-2019-2831
6.4 AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:L/A:L
Easily exploitable vulnerability allows low privileged attacker with
network access via HTTP to compromise the affected system. While the
vulnerability is in the affected system, attacks may significantly
impact additional products. Successful attacks of this vulnerability
can result in unauthorized update, insert or delete access to some of
the affected system's accessible data and unauthorized ability to
cause a partial denial of service (partial DOS) of the affected
system.
Affects:
o PeopleSoft Enterprise FIN Project Costing 9.2
CVE-2019-2772
6.1 AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
Easily exploitable vulnerability allows unauthenticated attacker with
network access via HTTP to compromise the affected system. Successful
attacks require human interaction from a person other than the
attacker and while the vulnerability is in the affected system,
attacks may significantly impact additional products. Successful
attacks of this vulnerability can result in unauthorized update,
insert or delete access to some of the affected system's accessible
data as well as unauthorized read access to a subset of the affected
system's accessible data.
Affects:
o PeopleSoft Enterprise PeopleTools 8.55, 8.56, 8.57
CVE-2019-11358
6.1 AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N

network access via HTTP to compromise the affected system. Successful
attacks require human interaction from a person other than the
attacker and while the vulnerability is in the affected system,
attacks may significantly impact additional products. Successful
attacks of this vulnerability can result in unauthorized update,
insert or delete access to some of the affected system's accessible
data as well as unauthorized read access to a subset of the affected
system's accessible data.
Affects:
o PeopleSoft Enterprise PeopleTools 8.55, 8.56, 8.57
CVE-2018-17960
6.1 AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N

attacker and while the vulnerability is in the affected system,
attacks may significantly impact additional products. Successful
attacks of this vulnerability can result in unauthorized update,
insert or delete access to some of the affected system's accessible
data as well as unauthorized read access to a subset of the affected
system's accessible data.
Affects:
o PeopleSoft Enterprise PeopleTools 8.55, 8.56, 8.57
CVE-2019-1559
5.9 AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N
Difficult to exploit vulnerability allows unauthenticated attacker
with network access via HTTPS to compromise the affected system.
Successful attacks of this vulnerability can result in unauthorized
access to critical data or complete access to all the affected
system's accessible data.
Affects:
o PeopleSoft Enterprise PeopleTools 8.55, 8.56, 8.57
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]
