[1] "CVE-2018-1000300 7.5 AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H The supported version that is affected is Prior to 18.3. Difficult to exploit vulnerability allows unauthenticated attacker with network access via HTTP to compromise OSS Support Tools. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in takeover of OSS Support Tools." [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."
