CVE-2018-2939: Vulnerability in the Core RDBMS component of Oracle Database Server.

Vulnerability in the Core RDBMS component of Oracle Database Server. Supported versions that are affected are 11.2.0.4, 12.1.0.2, 12.2.0.1, 18.1 and 18.2. Easily exploitable vulnerability allows low privileged attacker having Local Logon privilege with logon to the infrastructure where Core RDBMS executes to compromise Core RDBMS. While the vulnerability is in Core RDBMS, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Core RDBMS accessible data and unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Core RDBMS. CVSS 3.0 Base Score 8.4 (Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:H/A:H).

Security readout for executives and security teams

CVE-2018-2939 is a serious Oracle Database Core RDBMS flaw. A low-privileged user who can log on locally to the database infrastructure could alter critical data or crash the database. The source bundle does not show data theft impact, but integrity loss and outage risk are high. Exposure is most likely where affected Oracle Database versions run on systems that permit low-privileged local logon. This is not described as remotely exploitable without local infrastructure access. Treat as high priority for Oracle Database environments with local user access. The main business risks are unauthorized alteration of critical data and complete database denial of service, both of which can affect dependent applications and operations. Mitigation focus: Review Oracle's July 2018 Critical Patch Update guidance for CVE-2018-2939.; Apply relevant Oracle Database security patches or vendor-supported upgrades.; Restrict local logon access to database infrastructure to approved administrators..
