IMPACT
The vendor has provided the following information regarding the
vulnerabilities:
"This Critical Patch Update contains 4 new security patches, plus
additional third party patches noted below, for Oracle Construction
and Engineering. 1 of these vulnerabilities may be remotely
exploitable without authentication, i.e., may be exploited over a
network without requiring user credentials." [1]
"CVE-2022-45688
7.5 AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Supported versions that are affected are 19.12.0-19.12.17,
20.12.0-20.12.12 and 21.12.0-21.12.10. Easily exploitable
vulnerability allows unauthenticated attacker with network access via
HTTP to compromise Primavera Gateway. Successful attacks of this
vulnerability can result in unauthorized ability to cause a hang or
frequently repeatable crash (complete DOS) of Primavera Gateway.
Affects:
o Primavera Gateway 19.12.0-19.12.17, 20.12.0-20.12.12,
21.12.0-21.12.10
CVE-2023-2976

Supported versions that are affected are 19.12.0-19.12.17,
20.12.0-20.12.12 and 21.12.0-21.12.10. Easily exploitable
vulnerability allows low privileged attacker with logon to the
infrastructure where Primavera Gateway executes to compromise
Primavera Gateway. Successful attacks of this vulnerability can
result in unauthorized creation, deletion or modification access to
critical data or all Primavera Gateway accessible data as well as
unauthorized access to critical data or complete access to all
Primavera Gateway accessible data.
Affects:
o Primavera Gateway 19.12.0-19.12.17, 20.12.0-20.12.12,
21.12.0-21.12.10
CVE-2022-31160

Supported versions that are affected are 19.12.0-19.12.16,
20.12.0-20.12.16, 21.12.0-21.12.16 and 22.12.0-22.12.9. Easily
exploitable vulnerability allows low privileged attacker with network
access via HTTP to compromise Primavera Unifier. Successful attacks
require human interaction from a person other than the attacker.
Successful attacks of this vulnerability can result in unauthorized
read access to a subset of Primavera Unifier accessible data.
Affects:
o Primavera Unifier 19.12.0-19.12.16, 20.12.0-20.12.16,
21.12.0-21.12.16, 22.12.0-22.12.9

20.12.0-20.12.16, 21.12.0-21.12.16 and 22.12.0-22.12.9. Easily
exploitable vulnerability allows low privileged attacker with logon
to the infrastructure where Primavera Unifier executes to compromise
Primavera Unifier. Successful attacks of this vulnerability can
result in unauthorized read access to a subset of Primavera Unifier
accessible data.
Affects:
o Primavera Unifier 19.12.0-19.12.16, 20.12.0-20.12.16,
21.12.0-21.12.16, 22.12.0-22.12.9" [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]
