IMPACT

        The vendor has provided the following information regarding
        the vulnerabilities:
                
        "This Critical Patch Update contains 4 new security fixes
        for the Oracle Construction and Engineering Suite.   2 of
        these vulnerabilities may be remotely exploitable without
        authentication,  i.e.,  may be exploited over a network
        without requiring user credentials." [1]
                
                
                
        "CVE-2017-12617
                
        8.1
                
        AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
                
        Supported versions that are affected are 17.1 and 17.2.
        Difficult to exploit vulnerability allows unauthenticated
        attacker with network access via HTTP to compromise
        Instantis EnterpriseTrack.  Successful attacks of this
        vulnerability can result in takeover of Instantis
        EnterpriseTrack.
                
        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-2018-2849
                
        7.7
                
        AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N
                
        Supported versions that are affected are 16.2 and 17.1 –
        17.12. Easily exploitable vulnerability allows low
        privileged attacker with network access via HTTP to
        compromise Primavera P6 Enterprise Project Portfolio
        Management.  While the vulnerability is in Primavera P6
        Enterprise Project Portfolio Management, attacks may
        significantly impact additional products.  Successful
        attacks of this vulnerability can result in  unauthorized
        access to critical data or complete access to all Primavera
        P6 Enterprise Project Portfolio Management accessible data.
                
        CVE-2017-5662
                
        7.3
                
        AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:N/A:H
                
        The supported version that is affected is 6.3.0. Easily
        exploitable vulnerability allows low privileged attacker
        with network access via HTTP to compromise Oracle
        Communications MetaSolv Solution.  Successful attacks
        require human interaction from a person other than the
        attacker. Successful attacks of this vulnerability can
        result in  unauthorized access to critical data or complete
        access to all Oracle Communications MetaSolv Solution
        accessible data and unauthorized ability to cause a hang or
        frequently repeatable crash (complete DOS) of Oracle
        Communications MetaSolv Solution." [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]
