[1] CVE-2020-13956 7.5 AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N The supported version that is affected is Prior to 20.3. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle NoSQL Database. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle NoSQL Database accessible data. Affects: o Oracle NoSQL Database Prior to 20.3 CVE-2020-11612 7.5 AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H The supported version that is affected is Prior to 20.3. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle NoSQL Database. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle NoSQL Database. Affects: o Oracle NoSQL Database Prior to 20.3 CVE-2021-22883 7.5 AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H The supported version that is affected is Prior to 20.3. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle NoSQL Database. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle NoSQL Database. Affects: o Oracle NoSQL Database Prior to 20.3 CVE-2020-8908 3.3 AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N The supported version that is affected is Prior to 20.3. Easily exploitable vulnerability allows low privileged attacker with logon to the infrastructure where Oracle NoSQL Database executes to compromise Oracle NoSQL Database. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Oracle NoSQL Database accessible data. Affects: o Oracle NoSQL Database Prior to 20.3 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."
