**Name of the Vulnerable Software and Affected Versions** Oracle Database Server versions 19.3 through 19.26 Oracle Database Server versions 21.3 through 21.17 Oracle Database Server versions 23.4 through 23.7 **Description** The issue is related to the RAS Security component of Oracle Database Server. It allows a low-privileged attacker with network access via Oracle Net to compromise RAS Security, given they have User Account privilege. Successful attacks require human interaction from a person other than the attacker and can result in unauthorized creation, deletion, or modification access to critical data or all RAS Security accessible data, as well as unauthorized access to critical data or complete access to all RAS Security accessible data. **Recommendations** For versions 19.3 through 19.26, update to a version outside of this range to mitigate the risk. For versions 21.3 through 21.17, update to a version outside of this range to mitigate the risk. For versions 23.4 through 23.7, update to a version outside of this range to mitigate the risk. As a temporary workaround, consider restricting access to the RAS Security component until a patch is available.

**Name of the Vulnerable Software and Affected Versions** Oracle Database versions 19c through 21c **Description** The issue is related to insufficient input validation in the Oracle Database RDBMS Security component. It allows a low-privileged attacker with Create Session privilege and network access via Oracle Net to compromise Oracle Database RDBMS Security. Successful attacks require human interaction from a person other than the attacker and can result in unauthorized creation, deletion, or modification access to critical data, as well as unauthorized read access to a subset of Oracle Database RDBMS Security accessible data. **Recommendations** For Oracle Database versions 19c through 21c, consider restricting access to the Oracle Net network service to minimize the risk of exploitation until a patch is available. As a temporary workaround, limit the Create Session privilege to necessary users only. Avoid relying on human interaction that may facilitate successful attacks. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
