Summary

Vulnerability in the Core RDBMS component of Oracle Database Server. Supported versions that are affected are 12.1.0.2, 12.2.0.1, 18c and 19c. Easily exploitable vulnerability allows low privileged attacker having Local Logon privilege with logon to the infrastructure where Core RDBMS executes to compromise Core RDBMS. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Core RDBMS accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Core RDBMS. CVSS 3.0 Base Score 3.9 (Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:L/A:L).

descriptionThe remote Oracle Database Server is missing the January 2020 Critical Patch Update (CPU). It is, therefore, affected by multiple vulnerabilities: - A denial of service (DoS) vulnerability exists in the Core RDBMS component of Oracle Database Server. An authenticated, remote attacker can exploit this issue, to cause the application to stop responding. (CVE-2020-2511) - A remote code execution vulnerability exists in the Core RDBMS component of Oracle Database Server. An unauthenticated, remote attacker can exploit this to bypass authentication and execute arbitrary commands. (CVE-2020-2510) - An unspecified vulnerability exists in the JavaVM component of Oracle Database Server. An authenicated, remote attacker can exploit this issue, to affect the confidentiality, integrity and availability of the application. It is also affected by additional vulnerabilities; see the vendor advisory for more information. Note that Nessus has not tested for this issue but has instead relied only on the application
