OVERVIEW

        Multiple vulnerabilities have been identified in :
         o Oracle Real-Time Scheduler, versions 2.3.0.1-2.3.0.3
         o Oracle Utilities Framework, versions 4.2.0.2-4.2.0.3,
           4.3.0.1-4.3.0.4

         o Oracle Utilities Work and Asset Management (v1), version
           1.9.1.2
        [1]


IMPACT

        The vendor has provided the following information regarding the
        vulnerabilities:
        
        "This Critical Patch Update contains 4 new security patches for
        Oracle Utilities Applications. All 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
        The supported version that is affected is 1.9.1.2. Easily exploitable
        vulnerability allows unauthenticated attacker with network access via
        HTTP to compromise Oracle Utilities Work and Asset Management (v1).
        Successful attacks of this vulnerability can result in takeover of
        Oracle Utilities Work and Asset Management (v1).
         Affects:
         o Oracle Utilities Work and Asset Management (v1) 1.9.1.2
        
        CVE-2019-11358
          6.1 AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
        Supported versions that are affected are 2.3.0.1-2.3.0.3. Easily
        exploitable vulnerability allows unauthenticated attacker with
        network access via HTTP to compromise Oracle Real-Time Scheduler.
        Successful attacks require human interaction from a person other than
        the attacker and while the vulnerability is in Oracle Real-Time
        Scheduler, attacks may significantly impact additional products.
        Successful attacks of this vulnerability can result in unauthorized
        update, insert or delete access to some of Oracle Real-Time Scheduler
        accessible data as well as unauthorized read access to a subset of
        Oracle Real-Time Scheduler accessible data.
         Affects:
         o Oracle Real-Time Scheduler 2.3.0.1-2.3.0.3
         o Oracle Utilities Mobile Workforce Management 2.3.0.1-2.3.0.3
        
        CVE-2014-3004
          5.3 AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
        Supported versions that are affected are 4.2.0.2-4.2.0.3 and
        4.3.0.1-4.3.0.4. Easily exploitable vulnerability allows
        unauthenticated attacker with network access via HTTP to compromise
        Oracle Utilities Framework. Successful attacks of this vulnerability
        can result in unauthorized read access to a subset of Oracle
        Utilities Framework accessible data.
         Affects:
         o Oracle Utilities Framework 4.2.0.2-4.2.0.3, 4.3.0.1-4.3.0.4


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]
