OVERVIEW
Multiple vulnerabilities have been identified in :
o Oracle Banking Platform, versions 2.5.0, 2.6.0,

[1]
IMPACT
The vendor has provided the following information regarding the
vulnerabilities:
"This Critical Patch Update contains 2 new security fixes for Oracle
Financial Services Applications. Both of these vulnerabilities may
be remotely exploitable without authentication, i.e., may be
exploited over a network without requiring user credentials." [1]
"CVE-2018-12023
8.1
AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
Supported versions that are affected are 15.1, 15.2, 16.1, 16.2,
17.1-17.12 and 18.1-18.8. Difficult to exploit vulnerability allows
unauthenticated attacker with network access via HTTP to compromise
Primavera Unifier. Successful attacks of this vulnerability can
result in takeover of Primavera Unifier.
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 15.2, 16.2 and 17.12.
Easily exploitable vulnerability allows unauthenticated attacker with
network access via HTTP to compromise Primavera Gateway. Successful
attacks require human interaction from a person other than the
attacker and while the vulnerability is in Primavera Gateway, attacks
may significantly impact additional products. Successful attacks of
this vulnerability can result in unauthorized update, insert or
delete access to some of Primavera Gateway accessible data as well as
unauthorized read access to a subset of Primavera Gateway 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]
