        [1]


IMPACT

        The vendor has provided the following information regarding the
        vulnerabilities:
        
        "This Critical Patch Update contains 7 new security fixes for Oracle
        Insurance Applications. All of these vulnerabilities may be remotely
        exploitable without authentication, i.e., may be exploited over a
        network without requiring user credentials." [1]
        
        "CVE-2016-1000031
          9.8 AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
        Easily exploitable vulnerability allows unauthenticated attacker with
        network access via HTTP to compromise the affected system. Successful
        attacks of this vulnerability can result in takeover of the affected
        system.
         Affects:
         o Oracle Insurance Calculation Engine 9.7, 10.0, 10.1, 10.2
         o Oracle Insurance Policy Administration J2EE 10.0, 10.1, 10.2,
           11.0
         o Oracle Insurance Rules Palette 10.0, 10.1, 10.2, 11.0
        
        CVE-2018-15756
          7.5 AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
        Easily exploitable vulnerability allows unauthenticated attacker with
        network access via HTTP to compromise the affected system. Successful
        attacks of this vulnerability can result in unauthorized ability to
        cause a hang or frequently repeatable crash (complete DOS) of the
        affected system.
         Affects:
         o Oracle Insurance Calculation Engine 9.7, 10.0, 10.1, 10.2
         o Oracle Insurance Policy Administration J2EE 10.0, 10.1, 10.2,
           11.0
         o Oracle Insurance Rules Palette 10.0, 10.1, 10.2, 11.0
        
        CVE-2017-14735
          6.1 AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
        Easily exploitable vulnerability allows unauthenticated attacker with
        network access via HTTP to compromise the affected system. Successful
        attacks require human interaction from a person other than the
        attacker and while the vulnerability is in the affected system,
        attacks may significantly impact additional products. Successful
        attacks of this vulnerability can result in unauthorized update,
        insert or delete access to some of the affected system's accessible
        data as well as unauthorized read access to a subset of the affected
        system's accessible data.
         Affects:
         o Oracle Insurance Calculation Engine 9.7, 10.0, 10.1, 10.2" [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]
