CVSS v3.1
7.2
High
| Vector | AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
MySQL Server versions 5.7.33 and prior
MySQL Server versions 8.0.23 and prior
Description
The issue is related to insufficient input validation in the MySQL Server component, specifically in the Server: Replication subcomponent. This can be exploited by 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 MySQL Server versions 5.7.33 and prior, update to a version later than 5.7.33 to resolve the issue.
For MySQL Server versions 8.0.23 and prior, update to a version later than 8.0.23 to resolve the issue.
As a temporary workaround, consider restricting network access to the MySQL Server to minimize the risk of exploitation.
