CVE-2022-21278
CVSS v2.0
7.5
High
| Vector | AV:N/AC:L/Au:S/C:N/I:P/A:C |
Name of the Vulnerable Software and Affected Versions
MySQL Server versions 8.0.26 and prior
Description
The issue is related to insufficient input validation in the Server: Optimizer component of MySQL Server, allowing a low-privileged attacker with network access via multiple protocols to compromise the server. Successful attacks can result in unauthorized access to update, insert, or delete some of MySQL Server's accessible data, as well as cause a hang or frequently repeatable crash (complete DOS) of MySQL Server.
Recommendations
For versions 8.0.26 and prior, update to a version later than 8.0.26 to resolve the issue.
As a temporary workaround, consider restricting network access to the MySQL Server to minimize the risk of exploitation.
Avoid using the Server: Optimizer component until the issue is resolved.
At the moment, there is no information about additional mitigation measures.
