IMPACT

        The vendor has provided the following information regarding the
        vulnerabilities:
        
        "This Critical Patch Update contains 3 new security patches for
        Oracle Insurance Applications. 1 of these vulnerabilities may be
        remotely exploitable without authentication, i.e., may be exploited
        over a network without requiring user credentials." [1]
        [WARNING] Found details of CVE vary depending upon products
        
        CVE-2020-5421
          6.5 AV:N/AC:H/PR:L/UI:R/S:C/C:L/I:H/A:N
        Supported versions that are affected are 10.2.0, 10.2.4, 11.0.2 and
        11.1.0-11.3.0. Difficult to exploit vulnerability allows low
        privileged attacker with network access via HTTP to compromise Oracle
        Insurance Policy Administration. Successful attacks require human
        interaction from a person other than the attacker and while the
        vulnerability is in Oracle Insurance Policy Administration, attacks
        may significantly impact additional products. Successful attacks of
        this vulnerability can result in unauthorized creation, deletion or
        modification access to critical data or all Oracle Insurance Policy
        Administration accessible data as well as unauthorized read access to
        a subset of Oracle Insurance Policy Administration accessible data.
         Affects:
         o Oracle Insurance Policy Administration 10.2.0, 10.2.4, 11.0.2,
           11.1.0-11.3.0
         o Oracle Insurance Rules Palette 10.2.0, 10.2.4, 11.0.2,
           11.1.0-11.3.0
        
        CVE-2019-11358
          6.1 AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
        Supported versions that are affected are 5.0.0.20 and 5.1.1.03.
        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.
         Affects:
         o Oracle Insurance Insbridge Rating and Underwriting 5.0.0.20,
           5.1.1.03


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]
