Summary

Vulnerability in the Java VM component of Oracle Database Server. Supported versions that are affected are 11.2.0.4, 12.1.0.2, 12.2.0.1 and 18c. Easily exploitable vulnerability allows low privileged attacker having Create Session, Create Procedure privilege with network access via multiple protocols to compromise Java VM. 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 partial denial of service (partial DOS) of Java VM. CVSS 3.0 Base Score 3.5 (Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:L).

descriptionThe remote Oracle Database Server is missing the January 2019 Critical Patch Update (CPU). It is, therefore, affected by multiple vulnerabilities : - An authenticated remote database takeover vulnerability exists in the Oracle RDBMS. An authenticated, remote attacker with the Create Session, Execute Catalog Role privileges can exploit this via the Oracle Net protocol to take over the back-end database, resulting in the disclosure or manipulation of arbitrary data. (CVE-2019-2406) - An authenticated local database takeover vulnerability exists in the Oracle RDBMS. An authenticated, local attacker with the Local Logon privilege can exploit this, by convincing another user to perform an unspecified action, to take over the back-end database, resulting in the disclosure or manipulation of arbitrary data. (CVE-2019-2444) - A denial of service (DoS) vulnerability exists in the Oracle RDBMS. An authenticated, remote attacker with the Create Session, Create Procedure privileges can exploit this issue, via multiple network protocols, by convincing another use to perform an unspecified action, to cause the Java VM to stop responding. (CVE-2019-2547) Note that Nessus has not tested for these issues but has instead relied only on the application
