[1] "CVE-2016-1000031 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 the affected system. Successful attacks of this vulnerability can result in takeover of the affected system. Affects: o Primavera P6 Enterprise Project Portfolio Management 8.4, 15.1, 15.2, 16.1, 16.2, 17.7-17.12, 18.8 o Primavera Unifier 16.1, 16.2, 17.7-17.12, 18.8 CVE-2018-19362 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 the affected system. Successful attacks of this vulnerability can result in takeover of the affected system. Affects: o Primavera P6 Enterprise Project Portfolio Management 15.1, 15.2, 16.1, 16.2, 17.7-17.12, 18.8 o Primavera Unifier 16.1, 16.2, 17.7-17.12, 18.8 CVE-2018-11763 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 the affected system. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of the affected system. Affects: o Instantis EnterpriseTrack 17.1, 17.2, 17.3 CVE-2018-0734 5.9 AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N Difficult to exploit vulnerability allows unauthenticated attacker with network access via TLS to compromise the affected system. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all the affected system's accessible data. Affects: o Primavera P6 Enterprise Project Portfolio Management 8.4, 15.1, 15.2, 16.1, 16.2, 17.7-17.12, 18.8 CVE-2018-11784 4.3 AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise the affected system. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of the affected system's accessible data. Affects: o Instantis EnterpriseTrack 17.1, 17.2, 17.3 CVE-2019-2701 4.3 AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise the affected system. Successful attacks of this vulnerability can result in unauthorized read access to a subset of the affected system's accessible data. Affects: o Primavera P6 Enterprise Project Portfolio Management 18.8" [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."
