        [1]


IMPACT

        The vendor has provided the following information regarding
        to the vulnerabilities:
        
        "This Critical Patch Update contains 4 new security fixes for
        Oracle Hyperion.   3 of these vulnerabilities may be
        remotely exploitable without authentication,  i.e.,  may be
        exploited over a network without requiring user credentials."
        [1]
        
        CVE-2017-10310
        
        7.5
        
        AV:N/AC:L/PR:N/UI:N/S:U/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 Oracle Hyperion
        Financial Reporting.  Successful attacks of this
        vulnerability can result in  unauthorized access to critical
        data or complete access to all Oracle Hyperion Financial
        Reporting accessible data.
        
        CVE-2017-10312
        
        7.1
        
        AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:L/A:N
        
        The supported version that is affected is 11.1.2.4. Easily
        exploitable vulnerability allows unauthenticated attacker
        with network access via HTTP to compromise Oracle Hyperion
        BI+.  Successful attacks require human interaction from a
        person other than the attacker. Successful attacks of this
        vulnerability can result in  unauthorized access to critical
        data or complete access to all Oracle Hyperion BI+
        accessible data as well as  unauthorized update, insert or
        delete access to some of Oracle Hyperion BI+ accessible
        data.
        
        CVE-2017-10358
        
        6.4
        
        AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N
        
        The supported version that is affected is 11.1.2. Easily
        exploitable vulnerability allows low privileged attacker
        with network access via HTTP to compromise Oracle Hyperion
        Financial Reporting.  While the vulnerability is in Oracle
        Hyperion Financial Reporting, attacks may significantly
        impact additional products.  Successful attacks of this
        vulnerability can result in  unauthorized update, insert or
        delete access to some of Oracle Hyperion Financial Reporting
        accessible data as well as  unauthorized read access to a
        subset of Oracle Hyperion Financial Reporting accessible
        data.
        
        CVE-2017-10359
        
        5.4
        
        AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N
        
        The supported version that is affected is 11.1.2.4. Easily
        exploitable vulnerability allows unauthenticated attacker
        with network access via HTTP to compromise Oracle 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 Oracle Hyperion BI+ accessible data
        as well as  unauthorized read access to a subset of Oracle
        Hyperion BI+ 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]
