OVERVIEW

        Multiple vulnerabilities have been identified in :
         o Primavera P6 Enterprise Project Portfolio Management, versions
           8.4, 15.1, 15.2, 16.1, 16.2, 17.7-17.12, 18.8
         o Primavera Unifier, versions 16.1, 16.2, 17.1-17.12, 18.8
        [1]


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.   All of these
        vulnerabilities may be remotely exploitable without authentication,
        i.e., may be exploited over a network without requiring user
        credentials." [1]
        AppendixPVA
        
        "CVE-2018-9206
        
        9.8
        
        AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
        
        Supported versions that are affected are 16.1, 16.2, 17.1-17.12 and
        18.8. Easily exploitable vulnerability allows unauthenticated
        attacker with network access via HTTP to compromise Primavera
        Unifier.  Successful attacks of this vulnerability can result in
        takeover of Primavera Unifier.
        
        CVE-2018-14718
        
        8.1
        
        AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
        
        Supported versions that are affected are 16.1, 16.2, 17.1-17.12 and
        18.8. Difficult to exploit vulnerability allows unauthenticated
        attacker with network access via HTTP to compromise Primavera
        Unifier.  Successful attacks of this vulnerability can result in
        takeover of Primavera Unifier.
        
        CVE-2018-0732
        
        7.5
        
        AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
        
        Supported versions that are affected are 8.4, 15.1,15.2, 16.1,16.2,
        17.7-17.12 and  18.8. Easily exploitable vulnerability allows
        unauthenticated attacker with network access via HTTPS to compromise
        Primavera P6 Enterprise Project Portfolio Management.  Successful
        attacks of this vulnerability can result in unauthorized ability to
        cause a hang or frequently repeatable crash (complete DOS) of
        Primavera P6 Enterprise Project Portfolio Management.
        
        CVE-2019-2512
        
        4.7
        
        AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:L/A:N
        
        Supported versions that are affected are 8.4, 15.1, 15.2, 16.1, 16.2,
        17.7-17.12 and  18.8. Difficult to exploit vulnerability allows
        unauthenticated attacker with network access via HTTP to compromise
        Primavera P6 Enterprise Project Portfolio Management.  Successful
        attacks require human interaction from a person other than the
        attacker and 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 update, insert or delete access to some of
        Primavera P6 Enterprise Project Portfolio Management accessible data
        as well as  unauthorized read access to a subset of Primavera P6
        Enterprise Project Portfolio Management 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]
