IMPACT
The vendor has provided the following information regarding the

network without requiring user credentials." [1]
CVE-2021-2244
9.6 AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H
Supported versions that are affected are 11.1.2.4 and 12.2.1.4.
Easily exploitable vulnerability allows unauthenticated attacker with
network access via HTTP to compromise Hyperion Analytic Provider
Services. Successful attacks require human interaction from a person
other than the attacker and while the vulnerability is in Hyperion
Analytic Provider Services, attacks may significantly impact
additional products. Successful attacks of this vulnerability can
result in takeover of Hyperion Analytic Provider Services.
Affects:
o Hyperion Analytic Provider Services 11.1.2.4, 12.2.1.4
CVE-2021-2158
3.9 AV:N/AC:H/PR:H/UI:R/S:U/C:L/I:L/A:L
The supported version that is affected is 11.1.2.4. Difficult to
exploit vulnerability allows high privileged attacker with network
access via HTTP to compromise Hyperion Financial Management.
Successful attacks require human interaction from a person other than
the attacker. Successful attacks of this vulnerability can result in
unauthorized update, insert or delete access to some of Hyperion
Financial Management accessible data as well as unauthorized read
access to a subset of Hyperion Financial Management accessible data
and unauthorized ability to cause a partial denial of service
(partial DOS) of Hyperion Financial Management.
Affects:
o Hyperion Financial Management 11.1.2.4
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]
