Média
| Vetor | AV:N/AC:L/Au:S/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
Oracle MySQL versions 5.5.58 and prior
Oracle MySQL versions 5.6.38 and prior
Oracle MySQL versions 5.7.20 and prior
Description
The issue is related to the MySQL Server component, specifically the Server:Optimizer subcomponent, and is associated with inadequate access control management. It allows a low-privileged attacker with network access via multiple protocols to compromise the MySQL Server. Successful attacks can result in the unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of the MySQL Server.
Recommendations
For Oracle MySQL versions 5.5.58 and prior, update to a version later than 5.5.58 to resolve the issue.
For Oracle MySQL versions 5.6.38 and prior, update to a version later than 5.6.38 to resolve the issue.
For Oracle MySQL versions 5.7.20 and prior, update to a version later than 5.7.20 to resolve the issue.
As a temporary workaround, consider restricting network access to the MySQL Server to minimize the risk of exploitation.
