Medium
| Vector | AV:N/AC:L/Au:M/C:N/I:N/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 Memcached subcomponent. It 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, leading to a denial of service.
Recommendations
For Oracle MySQL version 5.6.41 and prior, update to a version later than 5.6.41.
For Oracle MySQL version 5.7.23 and prior, update to a version later than 5.7.23.
For Oracle MySQL version 8.0.12 and prior, update to a version later than 8.0.12.
As a temporary workaround, consider restricting access to the Memcached subcomponent to minimize the risk of exploitation.
Fix
Improper Access Control
