Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Core RDBMS (jackson-databind). CVSS 3.0 Base Score 5.7 (Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:H).

Security readout for executives and security teams

CVE-2019-2956 can let a low-privileged Oracle Database user crash or hang part of the database service. It does not describe data theft or data modification, but a repeatable denial of service can still disrupt business systems that depend on affected databases. Exposure is most likely where affected Oracle Database versions are still deployed and reachable over database network protocols by accounts with Create Session privilege. Internet exposure is not stated in the sources. Treat as a service-availability risk for business-critical Oracle databases. Prioritize patch verification and exposure reduction where affected databases support production, customer-facing, financial, or operational workflows. Mitigation focus: Review Oracle October 2019 CPU guidance for CVE-2019-2956.; Apply applicable Oracle Database security updates in supported maintenance windows.; Restrict database network access to trusted application and administration paths..
