[1] "CVE-2017-12617 8.1 AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H Supported versions that are affected are 17.1 and 17.2. Difficult to exploit vulnerability allows unauthenticated attacker with network access via HTTP to compromise Instantis EnterpriseTrack. Successful attacks of this vulnerability can result in takeover of Instantis EnterpriseTrack. CVE-2017-15095 8.1 AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H The supported version that is affected is 8.x. Difficult to exploit vulnerability allows unauthenticated attacker with network access via WCAP to compromise Oracle Communications Calendar Server. Successful attacks of this vulnerability can result in takeover of Oracle Communications Calendar Server. CVE-2018-2849 7.7 AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N Supported versions that are affected are 16.2 and 17.1 – 17.12. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Primavera P6 Enterprise Project Portfolio Management. While the vulnerability is in Primavera P6 Enterprise Project Portfolio Management, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Primavera P6 Enterprise Project Portfolio Management accessible data. CVE-2017-5662 7.3 AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:N/A:H The supported version that is affected is 6.3.0. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Communications MetaSolv Solution. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Communications MetaSolv Solution accessible data and unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle Communications MetaSolv Solution." [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."
