IMPACT

        The vendor has provided the following information:
        
        "CVE-2016-5019 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 Oracle Utilities Customer
        Self Service. Successful attacks of this vulnerability can result in
        takeover of Oracle Utilities Customer Self Service.
        
        CVE-2014-0114 8.3 AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:L
        Easily exploitable vulnerability allows unauthenticated attacker 
        with network access via HTTP to compromise Oracle Utilities 
        Framework. While the vulnerability is in Oracle Utilities Framework,
        attacks may significantly impact additional products. Successful 
        attacks of this vulnerability can result in unauthorized update, 
        insert or delete access to some of Oracle Utilities Framework 
        accessible data as well as unauthorized read access to a subset of 
        Oracle Utilities Framework accessible data and unauthorized ability
        to cause a partial denial of service (partial DOS) of Oracle 
        Utilities Framework.
        
        CVE-2016-3092 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 Oracle Utilities 
        components. Successful attacks of this vulnerability can result in 
        unauthorized ability to cause a hang or frequently repeatable crash
        (complete DOS) of Oracle Utilities components.
        
        CVE-2016-3674 7.5 AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
        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 access to critical data or complete access to all 
        Oracle Utilities Framework accessible data.
        
        CVE-2017-3537 6.1 AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
        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.
        
        CVE-2012-5881 6.1 AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
        Easily exploitable vulnerability allows unauthenticated attacker 
        with network access via HTTP to compromise Oracle Utilities 
        Framework. Successful attacks require human interaction from a 
        person other than the attacker and while the vulnerability is in 
        Oracle Utilities Framework, attacks may significantly impact 
        additional products. Successful attacks of this vulnerability can 
        result in unauthorized update, insert or delete access to some of 
        Oracle Utilities Framework accessible data as well as unauthorized 
        read access to a subset of Oracle Utilities Framework 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]
