OVERVIEW

        Multiple vulnerabilities have been identified in :
         o Oracle Insurance Data Gateway, version 1.0.2.3
        [1]


IMPACT

        The vendor has provided the following information regarding the
        vulnerabilities:
        
        "This Critical Patch Update contains 1 new security patch for Oracle
        Insurance Applications. This vulnerability is remotely exploitable
        without authentication, i.e., may be exploited over a network without
        requiring user credentials." [1]
        
        CVE-2019-10086
          7.3 AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L
        The supported version that is affected is 1.0.2.3. Easily exploitable
        vulnerability allows unauthenticated attacker with network access via
        HTTP to compromise Oracle Insurance Data Gateway. Successful attacks
        of this vulnerability can result in unauthorized update, insert or
        delete access to some of Oracle Insurance Data Gateway accessible
        data as well as unauthorized read access to a subset of Oracle
        Insurance Data Gateway accessible data and unauthorized ability to
        cause a partial denial of service (partial DOS) of Oracle Insurance
        Data Gateway.
         Affects:
         o Oracle Insurance Data Gateway 1.0.2.3


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]
