| Vector | AV:N/AC:L/Au:M/C:N/I:P/A:C |
Name of the Vulnerable Software and Affected Versions
Oracle MySQL versions 5.6.41 and prior
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 MySQL Server component, specifically in the Server: Merge subcomponent. This allows a high-privileged attacker with network access via multiple protocols to compromise the MySQL Server. Successful attacks can result in the ability to cause a hang or frequently repeatable crash of the MySQL Server, as well as unauthorized update, insert, or delete access to some of the MySQL Server's accessible data.
Recommendations
For Oracle MySQL version 5.6.41 and prior, update to a version later than 5.6.41 to resolve the issue.
For Oracle MySQL version 5.7.23 and prior, update to a version later than 5.7.23 to resolve the issue.
For Oracle MySQL version 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.
Fix
