OVERVIEW

        Multiple vulnerabilities have been identified in 
         Hyperion BI+, version  11.1.2.4
         Hyperion Data Relationship Management, version
          11.1.2.4.330
         Oracle Hyperion Planning, version  11.1.2.4.007
        [1]


IMPACT

        The vendor has provided the following information regarding
        the vulnerabilities:
        
        "This Critical Patch Update contains 4 new security fixes
        for Oracle Hyperion. 1 of these vulnerabilities may be
        remotely exploitable without authentication,  i.e.,  may be
        exploited over a network without requiring user
        credentials." [1]
        
        
        
        "CVE-2018-2733
        
        7.6
        
        AV:N/AC:H/PR:H/UI:R/S:C/C:H/I:H/A:H
        
        The supported version that is affected is 11.1.2.4.007.
        Difficult to exploit vulnerability allows high privileged
        attacker with network access via HTTP to compromise Oracle
        Hyperion Planning.  Successful attacks require human
        interaction from a person other than the attacker and while
        the vulnerability is in Oracle Hyperion Planning, attacks
        may significantly impact additional products. Successful
        attacks of this vulnerability can result in takeover of
        Oracle Hyperion Planning.
        
        CVE-2018-2610
        
        5.3
        
        AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
        
        The supported version that is affected is 11.1.2.4.330.
        Easily exploitable vulnerability allows unauthenticated
        attacker with network access via HTTP to compromise Hyperion
        Data Relationship Management.  Successful attacks of this
        vulnerability can result in  unauthorized read access to a
        subset of Hyperion Data Relationship Management accessible
        data.
        
        CVE-2018-2594
        
        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+.
        
        CVE-2018-2595
        
        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]
