        [1]


IMPACT

        The vendor has provided the following information regarding
        the vulnerabilities:
        
        "This Critical Patch Update contains 2 new security fixes
        for Oracle Hyperion.   Both of these vulnerabilities may be
        remotely exploitable without authentication,  i.e.,  may be
        exploited over a network without requiring user
        credentials." [1]
        
        
        
        "CVE-2018-2907
        
        8.6
        
        AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N
        
        The supported version that is affected is 11.1.2. Easily
        exploitable vulnerability allows unauthenticated attacker
        with network access via HTTP to compromise Hyperion
        Financial Reporting.  While the vulnerability is in Hyperion
        Financial Reporting, attacks may significantly impact
        additional products.  Successful attacks of this
        vulnerability can result in  unauthorized access to critical
        data or complete access to all Hyperion Financial Reporting
        accessible data.
        
        CVE-2018-2915
        
        5.8
        
        AV:N/AC:L/PR:N/UI:N/S:C/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 HTTPS to compromise
        Hyperion Data Relationship Management.  While the
        vulnerability is in Hyperion Data Relationship Management,
        attacks may significantly impact additional products.
        Successful attacks of this vulnerability can result in
        unauthorized read access to a subset of Hyperion Data
        Relationship Management accessible data." [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]
