IMPACT

        The vendor has provided the following information regarding
        the vulnerabilities:
        
        "This Critical Patch Update contains 3 new security fixes
        for Oracle JD Edwards Products.   All of these
        vulnerabilities may be remotely exploitable without
        authentication,  i.e.,  may be exploited over a network
        without requiring user credentials." [1]
        
        
        
        "CVE-2017-5645
        
        9.8
        
        AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
        
        The supported version that is affected is 7.3.x. Easily
        exploitable vulnerability allows unauthenticated attacker
        with network access via HTTP to compromise Oracle
        Communications Network Intelligence.  Successful attacks of
        this vulnerability can result in takeover of Oracle
        Communications Network Intelligence.
        
        CVE-2017-15095
        
        8.1
        
        AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
        
        The supported version that is affected is 8.x. Difficult to
        exploit vulnerability allows unauthenticated attacker with
        network access via WCAP to compromise Oracle Communications
        Calendar Server.  Successful attacks of this vulnerability
        can result in takeover of Oracle Communications Calendar
        Server.
        
        CVE-2017-3736
        
        5.9
        
        AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N
        
        Supported versions that are affected are 4.4.1.5.0,
        5.0.0.1.0, 5.0.0.2.0, 5.0.1.0.0 and  5.0.2.0.0. Difficult to
        exploit vulnerability allows unauthenticated attacker with
        network access via TLS to compromise Oracle Communications
        Network Charging and Control.  Successful attacks of this
        vulnerability can result in  unauthorized access to critical
        data or complete access to all Oracle Communications Network
        Charging and Control 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]
