[1] "CVE-2020-35169 9.8 AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H The supported version that is affected is 19c. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTPS to compromise Oracle GoldenGate. Successful attacks of this vulnerability can result in takeover of Oracle GoldenGate. Affects: o Oracle GoldenGate 19c CVE-2018-18893 4.3 AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N The supported version that is affected is 19c. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Goldengate. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Oracle Goldengate accessible data. Affects: o Oracle Goldengate 19c" [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."
