[1] 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."
