| Vector | AV:A/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Oracle MySQL versions 5.6.42 and prior
Oracle MySQL versions 5.7.24 and prior
Oracle MySQL versions 8.0.13 and prior
Description
The issue is related to insufficient access control in the MySQL Server component, specifically in the Server: Connection Handling subcomponent. It allows an attacker with access to the physical communication segment or network access via multiple protocols to compromise the MySQL Server. Successful attacks can result in unauthorized access to critical data, complete access to all MySQL Server accessible data, or the ability to cause a hang or frequently repeatable crash (complete DOS) of the MySQL Server.
Recommendations
For Oracle MySQL versions 5.6.42 and prior, update to a version later than 5.6.42 to resolve the issue.
For Oracle MySQL versions 5.7.24 and prior, update to a version later than 5.7.24 to resolve the issue.
For Oracle MySQL versions 8.0.13 and prior, update to a version later than 8.0.13 to resolve the issue.
As a temporary workaround, consider restricting network access to the MySQL Server to minimize the risk of exploitation.
