GSD-2020-2517

Vulnerability from gsd - Updated: 2023-12-13 01:21
Details
Vulnerability in the Database Gateway for ODBC component of Oracle Database Server. Supported versions that are affected are 11.2.0.4, 12.1.0.2, 12.2.0.1, 18c, and 19c. Difficult to exploit vulnerability allows high privileged attacker having Create Procedure, Create Database Link privilege with network access via OracleNet to compromise Database Gateway for ODBC. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Database Gateway for ODBC accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Database Gateway for ODBC. CVSS 3.0 Base Score 3.3 (Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:H/UI:N/S:U/C:N/I:L/A:L).
