OVERVIEW

        Multiple vulnerabilities have been identified in 
         Oracle Enterprise Manager Ops Center, versions  12.2.2,
          12.3.2
        [1]


IMPACT

        The vendor has provided the following information regarding
        to the vulnerabilities:
        
        "This Critical Patch Update contains 1 new security fix for
        Oracle Enterprise Manager Grid Control.   This vulnerability
        is remotely exploitable without authentication,  i.e.,  may
        be exploited over a network without requiring user
        credentials.   This fix is not applicable to client-only
        installations,  i.e., installations that do not have Oracle
        Enterprise Manager Grid Control  installed.  The English
        text form of this Risk Matrix can be found here."
        [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]
