        [1]


IMPACT

        The vendor has provided the following information regarding the
        vulnerabilities:
        
        "This Critical Patch Update contains 8 new security fixes for the
        Oracle Construction and Engineering Suite. 7 of these vulnerabilities
        may be remotely exploitable without authentication, i.e., may be
        exploited over a network without requiring user credentials." [1]
        
        "CVE-2016-1000031
          9.8 AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
        Easily exploitable vulnerability allows unauthenticated attacker with
        network access via HTTP to compromise the affected system. Successful
        attacks of this vulnerability can result in takeover of the affected
        system.
         Affects:
         o Primavera P6 Enterprise Project Portfolio Management 8.4, 15.1,
           15.2, 16.1, 16.2, 17.7-17.12, 18.8
         o Primavera Unifier 16.1, 16.2, 17.7-17.12, 18.8
        
        CVE-2018-19362
          9.8 AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
        Easily exploitable vulnerability allows unauthenticated attacker with
        network access via HTTP to compromise the affected system. Successful
        attacks of this vulnerability can result in takeover of the affected
        system.
         Affects:
         o Primavera P6 Enterprise Project Portfolio Management 15.1,
           15.2, 16.1, 16.2, 17.7-17.12, 18.8
         o Primavera Unifier 16.1, 16.2, 17.7-17.12, 18.8
        
        CVE-2018-11763
          7.5 AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
        Easily exploitable vulnerability allows unauthenticated attacker with
        network access via HTTP to compromise the affected system. Successful
        attacks of this vulnerability can result in unauthorized ability to
        cause a hang or frequently repeatable crash (complete DOS) of the
        affected system.
         Affects:
         o Instantis EnterpriseTrack 17.1, 17.2, 17.3
        
        CVE-2018-0734
          5.9 AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N
        Difficult to exploit vulnerability allows unauthenticated attacker
        with network access via TLS to compromise the affected system.
        Successful attacks of this vulnerability can result in unauthorized
        access to critical data or complete access to all the affected
        system's accessible data.
         Affects:
         o Primavera P6 Enterprise Project Portfolio Management 8.4, 15.1,
           15.2, 16.1, 16.2, 17.7-17.12, 18.8
        
        CVE-2018-11784
          4.3 AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N
        Easily exploitable vulnerability allows unauthenticated attacker with
        network access via HTTP to compromise the affected system. Successful
        attacks require human interaction from a person other than the
        attacker. Successful attacks of this vulnerability can result in
        unauthorized update, insert or delete access to some of the affected
        system's accessible data.
         Affects:
         o Instantis EnterpriseTrack 17.1, 17.2, 17.3
        
        CVE-2019-2701
          4.3 AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N
        Easily exploitable vulnerability allows low privileged attacker with
        network access via HTTP to compromise the affected system. Successful
        attacks of this vulnerability can result in unauthorized read access
        to a subset of the affected system's accessible data.
         Affects:
         o Primavera P6 Enterprise Project Portfolio Management 18.8" [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]
