6.8
Medium
| Vector | AV:N/AC:L/Au:S/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
MySQL Server versions 5.7.29 and prior
MySQL Server versions 8.0.19 and prior
Description
The issue is related to the Optimizer component of the MySQL Server, which is affected by a lack of access control. 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 (complete DOS) of the MySQL Server. The vulnerability can be exploited remotely using the MySQL Protocol.
Recommendations
For MySQL Server versions 5.7.29 and prior, update to a version later than 5.7.29 to resolve the issue.
For MySQL Server versions 8.0.19 and prior, update to a version later than 8.0.19 to resolve the issue.
As a temporary workaround, consider restricting network access to the MySQL Server to minimize the risk of exploitation.
