OVERVIEW

        A vulnerability has been identified in :
         o Hyperion BI+, version 11.1.2.4
        [1]


IMPACT

        The vendor has provided the following information regarding the
        vulnerability:
        
        "This Critical Patch Update contains 1 new security fix for Oracle
        Hyperion. This vulnerability is not remotely exploitable without
        authentication, i.e., may not be exploited over a network without
        requiring user credentials." [1]
        AppendixHYP
        
        "CVE-2019-2415
        
        4.3
        
        AV:N/AC:L/PR:H/UI:R/S:U/C:L/I:L/A:L
        
        The supported version that is affected is 11.1.2.4. Easily
        exploitable vulnerability allows high privileged attacker with
        network access via HTTP to compromise Hyperion BI+. 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 BI+
        accessible data as well as unauthorized read access to a subset of
        Hyperion BI+ accessible data and unauthorized ability to cause a
        partial denial of service (partial DOS) of Hyperion BI+." [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]
