CVE-2018-3187

Name of the Vulnerable Software and Affected Versions Oracle MySQL versions 5.7.23 and prior Oracle MySQL versions 8.0.12 and prior

Description The issue is related to insufficient access control in the Server: Optimizer component of Oracle MySQL, allowing a remote attacker to modify file permissions or cause a denial of service. Successful attacks can result in unauthorized access to update, insert, or delete data, as well as cause a hang or crash of the MySQL Server.

Recommendations For Oracle MySQL versions 5.7.23 and prior, update to a version later than 5.7.23 to resolve the issue. For Oracle MySQL versions 8.0.12 and prior, update to a version later than 8.0.12 to resolve the issue. As a temporary workaround, consider restricting network access to the MySQL Server to minimize the risk of exploitation.
