Name of the Vulnerable Software and Affected Versions Oracle Database Server versions 12.1.0.2, 12.2.0.1 and 19c

Description The issue exists due to insufficient input validation in the Oracle Text component of Oracle Database Server. This allows a remote attacker to execute arbitrary code using the Oracle Net protocol. The vulnerability can be easily exploited by a high-privileged attacker with Create Any Procedure, Alter Any Table privilege and network access via Oracle Net, potentially resulting in the takeover of Oracle Text.

Recommendations For version 12.1.0.2, update to a version that includes the fix for this issue. For version 12.2.0.1, update to a version that includes the fix for this issue. For version 19c, update to a version that includes the fix for this issue. As a temporary workaround, consider restricting access to the Oracle Text component until a patch is available.
