OVERVIEW

        Multiple vulnerabilities have been identified in :
         o Oracle Hyperion Infrastructure Technology, version 11.2.16.0.0
         o Oracle Smart View for Office, version 11.2.16.0.0
        [1]



IMPACT

        The vendor has provided the following information regarding the
        vulnerabilities:

        "This Critical Patch Update contains 2 new security patches for
        Oracle Hyperion. Neither of these vulnerabilities may be remotely
        exploitable without authentication, i.e., neither may be exploited
        over a network without requiring user credentials." [1]

        "CVE-2023-6246
         7.8 AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
        The supported version that is affected is 11.2.16.0.000. Easily
        exploitable vulnerability allows low privileged attacker with logon
        to the infrastructure where Oracle Hyperion Infrastructure
        Technology
        executes to compromise Oracle Hyperion Infrastructure Technology.
        Successful attacks of this vulnerability can result in takeover of
        Oracle Hyperion Infrastructure Technology.
         Affects:
         o Oracle Hyperion Infrastructure Technology 11.2.16.0.000

        CVE-2023-29081
         5.5 AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
        The supported version that is affected is 11.2.16.0.000. Easily
        exploitable vulnerability allows low privileged attacker with logon
        to the infrastructure where Oracle Smart View for Office executes
        to
        compromise Oracle Smart View for Office. Successful attacks of this
        vulnerability can result in unauthorized ability to cause a hang or
        frequently repeatable crash (complete DOS) of Oracle Smart View for
        Office.
         Affects:
         o Oracle Smart View for Office 11.2.16.0.000" [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]
