CVE-2020-14867
CVSS v2.0
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 5.6.49 and prior
MySQL Server versions 5.7.31 and prior
MySQL Server versions 8.0.21 and prior
Description:
The issue is related to insufficient input validation in the MySQL Server component, specifically in the DDL subcomponent. This can be exploited by a remote attacker to cause a denial of service, resulting in the ability to hang or crash the MySQL Server. The attack can be performed via multiple protocols and requires high privileges. The estimated number of potentially affected devices is not specified.
Recommendations:
For MySQL Server versions 5.6.49 and prior, update to a version later than 5.6.49 to resolve the issue.
For MySQL Server versions 5.7.31 and prior, update to a version later than 5.7.31 to resolve the issue.
For MySQL Server versions 8.0.21 and prior, update to a version later than 8.0.21 to resolve the issue.
As a temporary workaround, consider restricting network access to the MySQL Server to minimize the risk of exploitation.
