IMPACT

        The vendor has provided the following information regarding the
        vulnerabilities:
        
        "This Critical Patch Update contains 4 new security fixes for Oracle
        Insurance Applications. 3 of these vulnerabilities may be remotely
        exploitable without authentication, i.e., may be exploited over a
        network without requiring user credentials." [1]
        
        "CVE-2018-1258
        
        8.8
        
        AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
        
        The supported version that is affected is 10.2. Easily exploitable
        vulnerability allows low privileged attacker with network access via
        HTTP to compromise Oracle Insurance Calculation Engine.  Successful
        attacks of this vulnerability can result in takeover of Oracle
        Insurance Calculation Engine.
        
        CVE-2018-8013
        
        7.3
        
        AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L
        
        Supported versions that are affected are 10.0 and  10.2. Easily
        exploitable vulnerability allows unauthenticated attacker with
        network access via HTTP to compromise Oracle Insurance Policy
        Administration J2EE.  Successful attacks of this vulnerability can
        result in  unauthorized update, insert or delete access to some of
        Oracle Insurance Policy Administration J2EE accessible data as well
        as  unauthorized read access to a subset of Oracle Insurance Policy
        Administration J2EE accessible data and unauthorized ability to cause
        a partial denial of service (partial DOS) of Oracle Insurance Policy
        Administration J2EE.
        
        CVE-2015-9251
        
        6.1
        
        AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
        
        Supported versions that are affected are 5.2, 5.4 and  5.5. Easily
        exploitable vulnerability allows unauthenticated attacker with
        network access via HTTP to compromise Oracle Insurance Insbridge
        Rating and Underwriting. Successful attacks require human
        interaction from a person other than the attacker and while the
        vulnerability is in Oracle Insurance Insbridge Rating and
        Underwriting, attacks may significantly impact additional products.
        Successful attacks of this vulnerability can result in  unauthorized
        update, insert or delete access to some of Oracle Insurance Insbridge
        Rating and Underwriting accessible data as well as  unauthorized read
        access to a subset of Oracle Insurance Insbridge Rating and
        Underwriting accessible data.
        
        CVE-2017-14735
        
        6.1
        
        AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
        
        Supported versions that are affected are 10.0 and  10.2. Easily
        exploitable vulnerability allows unauthenticated attacker with
        network access via HTTP to compromise Oracle Insurance Policy
        Administration J2EE. Successful attacks require human interaction
        from a person other than the attacker and while the vulnerability is
        in Oracle Insurance Policy Administration J2EE, attacks may
        significantly impact additional products. Successful attacks of this
        vulnerability can result in unauthorized update, insert or delete
        access to some of Oracle Insurance Policy Administration J2EE
        accessible data as well as  unauthorized read access to a subset of
        Oracle Insurance Policy Administration J2EE 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]
