OVERVIEW

        Oracle Construction and Engineering Suite
        Multiple vulnerabilities have been identified in 
        Primavera Unifier, versions  9.13,  9.14,  10.x,  15.x, 16.x
        [1]


IMPACT

        The vendor has provided the following information regarding
        to the vulnerabilities:
        
        "This Critical Patch Update contains 1 new security fix for
        the Oracle Construction and Engineering Suite.   This
        vulnerability is remotely exploitable without
        authentication,  i.e.,  may be exploited over a network
        without requiring user credentials."
        [1]
        
        "CVE-2016-6814
        
        8.3
        
        AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H
        
        Difficult to exploit vulnerability allows unauthenticated
        attacker with network access via multiple protocols to
        compromise Spatial (Apache Groovy).  Successful attacks
        require human interaction from a person other than the
        attacker and while the vulnerability is in Spatial (Apache
        Groovy), attacks may significantly impact additional
        products. Successful attacks of this vulnerability can
        result in takeover of Spatial (Apache Groovy). Note:
        Component installed optionally. Not in the default
        installation."
        [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]
